Dexal Oxy Blu Stain Remover by Eurospin: Review of the Low-Cost "Percarbonate" That Saves Your Laundry

Percarbonate (or rather: active oxygen) is one of those products that, once you learn how to use it well, really changes the way you manage your laundry. Eurospin's Dexal Smacchiatore Oxy Blu promises just that: a powder additive designed for white and colored garments, useful both in the washing machine and by soaking, with a formula based on oxygen-based bleaches.

If you've ever wondered if "it really works" or if it's just a cheap way of saying sodium percarbonateHere you'll find a complete review: how to use it, which stains it works best on, what mistakes to avoid, and how to achieve visible results without ruining fabrics.

Dexal Oxy Blu Stain Remover by Eurospin: Review of the Low-Cost "Percarbonate" That Saves Your Laundry

There is a category of products that in laundries and in cleaning in property It makes more of a difference than the detergent itself: the additives. And of all the cleaners, those based on active oxygen are often the most underrated and at the same time the most effective. They're not perfumes, they're not fabric softeners, they're not 30-second magic: they're simple (and useful) chemistry that works when the temperature, time, and dosage are right.

Dexal Smacchiatore Oxy Blu, sold by Eurospin in 1 kg packs, was created specifically for this purpose: to provide tangible relief when garments appear "clean but dull," when stains remain as grayish shadows, when towels and sheets lose their shine, or when colored fabrics tend to darken and retain odors. Eurospin describes it as a stain remover for white and colored fabrics; various sources place it in the family of powder additives with a high percentage of oxygen-based bleaches.

Dexal Bianco Più and Dexal Oxy Blu: the differences that really matter

Within the Dexal laundry line, Eurospin offers more than one variant based on active oxygen, and it's easy to get confused between the different names and colors of the packages. In addition to the Oxy Blu Stain Remover, we also find Dexal White Plus, often recognizable by its red packaging. Both belong to the same "family" of active oxygen-based stain removers, but are designed for slightly different needs.

The main difference is not so much in the overall effectiveness – which remains high in both cases – but rather in the approach to the formulaOxy Blu is conceived as a more transversal stain remover, also suitable for coloured and technical fabrics, while Bianco Più is more decisively oriented towards brightness of white garments and maintaining whiteness over time.

What is Dexal Smacchiatore Oxy Blu (and why many call it “percarbonate”)

Dexal Oxy Blu Stain Remover is a powdered stain remover additive for laundry. The promise is typical of the "oxy": to help remove stains, revive and sanitize thanks to the release of active oxygen in water (especially warm/hot).

When we say "percarbonate" in Italy, we often mean generically "powder that releases active oxygen." In reality, pure percarbonate is a specific ingredient, while a commercial product like Oxy Blu may also include:

• anti-caking agents,
• “support” salts,
• adjuvants that aid dissolution or stability,
• sometimes small amounts of surfactants.

In practice, however, for home use, what matters is this: if it is an oxy powder with a high percentage of oxygen-based bleaches, it works like a “family” percarbonate and works best on oxidizable stains (wine, fruit, sweat, yellowing, streaks).

How active oxygen works on laundry

The principle is simple: in water, oxygen-based bleaches release active oxygen that:

• oxidizes (i.e. “breaks”) many molecules responsible for stains and yellowing,
• helps reduce the gray and dull effect of whites,
• helps with odors retained by thick fibers (towels, dishcloths).

This action is different from chlorine bleach: Active oxygen is generally more manageable and suitable for many resistant colors (always with common sense), while chlorine is more aggressive and selective.

The key point: active oxygen = time + temperature + sufficient waterIf you throw it in the washing machine at 20°C and run a very quick cycle, it often can't work miracles. If, however, you combine it with 40–60°C or a soak, everything changes.

Active oxygen and enzymes: why Oxy Blu works even at low temperatures

An element that deserves further investigation is the presence, in the version Oxy Blue, enzymes which work synergistically with active oxygen. This detail explains why many users notice good results even at medium-low temperatures.

Enzymes are particularly effective against:

• food residues
• protein stains (sweat, milk, eggs)
• dirt "stuck" in the fibres of technical or sports fabrics

In practice, while the active oxygen works by oxidizing and sanitizing, the enzymes help break down the stain's structure. This makes Oxy Blu an attractive choice for those who frequently wash at 30–40°C and need extra support without resorting to harsh treatments.

At what temperature does it really perform at its best?

We've already made it clear in our article that active oxygen loves heat, but here it's worth being even more precise. Dexal Oxy Blu starts to work already at 30°C, thanks to the enhanced formula, but expresses its maximum potential among the 50 to 60 °C.

This means that:

• at low temperatures it helps especially with fresh stains and odors
• at medium-high temperatures it works deeply on yellowing, greyness and “tired” laundry

It's the classic product that gives progressive results: used consistently in the right washes, it visibly improves the appearance of fabrics over time.

Who I recommend it to (and who I don't)

Dexal Oxy Blu makes sense if:

You're on the "whites who need to get bright again" team.
Sheets, pillowcases, white t-shirts, underwear, towels: here, active oxygen is often the best ally because it works on the "accumulated grayness".

You have recurring organic stains and halos
Sweat, deodorant, tea/coffee, fruit, light sauce, grass: these are stains that respond well to active oxygen + soaking or adequate washing.

Want a cheap wildcard additive?
The 1 kg package and its discount positioning make it a product to “keep at home” without thinking too much about it.

Instead, you may want to avoid it (or use it with great caution) if:

You often have delicate clothes
Wool, silk, delicate viscose, items with fragile elastic, unusual embroidery: it's best not to improvise.

You almost always wash in cold water and on rapid cycles
Not because it's "useless," but because it's less effective. In that case, it's best to look at other types of stain removers or use targeted soaking.

How to use it in the washing machine: the most effective strategy

When you use it as an additive, the goal is to make it dissolve well and let it work long enough.

1) Where to put it

Typically, powdered additives like these can be put:

• in the tray together with the detergent,
• or directly into the basket (often a more effective solution if you want to make sure it enters the water immediately and doesn't remain in the tank).

If you wash at low temperatures and happen to have residues left, the drum tends to reduce that risk, because the water hits it immediately.

2) Temperature: the real “trick”

If you can choose, 40°C is often the smart threshold: already enough to activate the active oxygen well, without being as aggressive as 60°C on some colored hair.

For “tough” whites (towels, sheets) the 60°C It is the level that often makes the most visible difference, especially on yellowing and greyness.

3) Cycle: not too short

Active oxygen works over time. If you want results, avoid flash cycles when your goal is stain removal/whitening.

Soaking: the method that makes the product seem “much more powerful”

If there's one thing that makes oxy-foods so popular, it's soaking. Why? Because you're giving chemistry its favorite ingredient: il tempo.

Soaking for dull or yellowed whites

• warm/hot water (not boiling)
• well-dissolved product
• completely immersed garments
• time: 30 minutes to a few hours, depending on the fabric

Soaking on specific stains

On sweat stains, fruit or tea stains:

• pre-treat by wetting the area
• then a short soak
• then washing machine

Washing the clothes in the washing machine after soaking helps eliminate residues and complete the cleaning.

“Smart” pretreatment: when the stain is localized

For specific stains (collar, armpits, cuffs), it often works best like this:

1. moisten the area,
2. make a soft paste (powder + very little water),
3. apply,
4. let it work for a while (without letting it dry completely),
5. wash.

It's a simple technique, but it's the one that often makes you say, "Okay, now I understand what this really does."

On which stains does it work best?

Active oxygen stain removers are particularly effective on:

• sweat and yellowing
• fruit stains (raspberries, strawberries, citrus fruits…)
• tea and coffee
• grass
• greyish accumulation halos
• “trapped” odors in sponge and thick cotton

The more “organic” the stain, the more likely the active oxygen is to do a good job.

There are stains that often do not go away with active oxygen alone:

• pure fat (oil, butter): you need a good surfactant/degreaser there
• very silicone-based foundation or “stubborn” pigments: specific pre-treatment is often required
• rust: requires dedicated products
• old stains baked in by the dryer: they may lighten but not disappear

The smartest way to use Oxy Blu is to consider it a transversal ally, not the only soldier.

Fabrics and colors: how to avoid damage and fading

Eurospin indicates it for whites and colors, but common sense is: always test if you have any doubts.

Colourful: yes, but with discretion

• OK on resistant colors (cotton, some stable synthetics)
• be more careful with very dark colors, new items that fade, delicate prints

Delicate: be careful

I'd avoid it on wool and silk. On viscose/acetate and "precious" garments, I'd test them or choose gentler alternatives.

Safety and incompatibility: two rules that save you

1. Do not mix with acids (such as vinegar or limescale remover) in the same container: active oxygen is an oxidant, and “mixing randomly” is never a good idea.
2. Do not mix with chlorine bleach: Not only is it useless, it can be risky. It's better to choose one approach or the other.

In normal use (washing machine/separate soaking) there is nothing "scary", just follow the basic instructions for the detergent product.

The smell: what to really expect

One thing that many people notice with oxy powders is that they don't make the laundry smell goodAnd that's a good thing if you hate overpowering scents. The perceived effect is often more "clean neutral" than "floral laundry."

If you want scent, it needs to come from detergent/fabric softener (or laundry fragrance), not from activated oxygen.

Value for money: why it's interesting

Dexal Oxy Blu is sold in 1 kg packs, so it was created as a “stock” product.
The advantage of cheap oxys, when they work well, is that they allow you to:

• reduce the amount of more expensive whiteners,
• avoid repeated washing (which consumes water, energy and fabrics),
• manage whites and sponges better without aggressive treatments.

If you use it only when needed (whites/sponges/sheets + specific stains), it often lasts a long time.

A more conscious choice for those who also care about the environment

Another aspect that is worth highlighting is the environmental profile of these products. Sodium percarbonate-based additives differ from traditional bleaches because, once dissolved in water, they decompose into substances considered to have a low environmental impact.

The absence of:

• optical brighteners
• chlorine
• invasive fragrances

This makes them particularly attractive for those seeking effective laundry that's both gentle on fibers and the environment. It's also one of the reasons why many prefer them to traditional bleach, especially for frequent use.

Which one to choose between Bianco Più and Oxy Blu?

If we had to summarize in a practical way:

• Dexal White Plus
  Ideal for those looking for a simple, white-focused formula without any additives. Perfect for sheets, towels, cotton, and household laundry.
• Dexal Oxy Blue Stain Remover
  More versatile, more suitable for resistant colored garments, sportswear and modern fabrics, thanks to the enzymatic support that also works at lower temperatures.

In both cases we are talking about products from extremely competitive quality-price ratio, which allow you to obtain visible results without resorting to expensive or aggressive solutions.

Comparison: Dexal Oxy Blue vs. pure percarbonate

Pure percarbonate is, so to speak, the "naked and raw ingredient." A commercial product like Oxy Blu may instead include adjuvants that:

• improve smoothness,
• reduce packing,
• They help with washing machine management.

In domestic practice, the biggest difference you make is with:

• temperature,
• soaking,
• consistency (don't wait for the whites to turn gray "forever").

If you're a DIY enthusiast and want total control, pure percarbonate makes sense. If you want convenience and immediate availability, Oxy Blu is more "ready to use."

Comparison: Active oxygen vs. bicarbonate

Baking soda is excellent as a deodorant and as a gentle support, but it's not a real whitenerActive oxygen, on the other hand, works specifically on lightening and oxidizable stains. If your priority is "brighter whites," oxy almost always wins.

Why these products have become "never without"

The success of additives like Dexal Oxy Blu is no coincidence. They respond to a very specific need: get really clean, bright and sanitized laundry without complicating your routineThey don't require any special care, they can be easily integrated with your regular detergent, and if used wisely, they can really make a difference in the long run.

These are products that don't make a splash, but which – once understood – end up becoming a permanent fixture in the laundry room pantry.

My final thoughts

If you are looking for a simple, economical and useful product for visibly improve whites, sponges and everyday garments, Dexal Smacchiatore Oxy Blu has all the right characteristics to become a “never without”: it is designed for whites and colors, it clearly belongs to the family of active oxygen additives and, as often happens with these products, It's at its best when you use it right.: 40–60°C when you can, soaking when necessary, and a little patience with stains.

I consider it particularly suitable for:

• towels and sheets that have lost their shine
• white t-shirts with light halo
• “family” laundry where stains are inevitable
• who wants an effective additive without spending a lot

If, however, you always wash in cold water and want immediate results in 15 minutes, you risk being disappointed: not because the product is poor, but because active oxygen needs favorable conditions.

Conclusion

In a world where we often look for a "miracle" product, I like Dexal Oxy Blu precisely because it's the opposite: it's a concrete additive that works well when you treat it like a technical ally. It doesn't tell you fairy tales, it doesn't promise boutique perfumes, it doesn't replace a good detergent... but It can really improve the overall performance of your washes, especially on whites and sponges, and can make a difference on many everyday stains that otherwise remain as halos.

If you want to get the most out of it, I'll leave you with the golden rule that applies to all oxy products (and which, when applied, makes the product seem "superior level"): do not rushA cycle that's not too short, an appropriate temperature when possible, and, when the situation calls for it, a thorough soak. This is where active oxygen truly comes into its own.
