Ayudin Antihongos is a specialized product for combating fungus, mold, and black stains in the home (kitchen, bathroom, showers, walls, tiles, and grout). It combines powerful bleaching, disinfecting, and fungicidal properties, making it one of the most popular products in this category on the Argentine household cleaning market.

How it works: Chemistry vs. microbiology

Mould and mildew are microorganisms (fungal microbes) that reproduce through spores and form branched fungal threads called mycelium that penetrate the structure of surfaces. To effectively eliminate mould, a product must either destroy the cellular structures of these microorganisms or create an environment in which they cannot survive.

Here are the key mechanisms of action of the active components of such products:

1. Oxidation and denaturation of cells

Many antifungal agents (especially those containing chlorine/bleach) act as oxidisers: they destroy the cell walls of fungal spores and denature the proteins that make up the fungus. This process results in the death of the microorganism on the surface.

2. Superficial destruction of spores and reduction of their viability

Chemical components disrupt the integrity of fungal cell membranes, preventing spore division and dissemination. Many commercial antifungal products contain surfactants, which help the chemicals better coat the surface and penetrate microcracks.

3. Limitations of traditional bleaches (chlorine)

Pure household chlorine (such as regular household bleach) effectively kills visible microscopic growths on non-porous surfaces (tiles, glass). However, on porous materials (concrete, wood, drywall), it may not penetrate deeply enough, and the water from the solution may even dampen the surface, creating favourable conditions for regrowth.

This is why modern mould and mildew removal products, such as Ayudin Antihongos, contain combined active ingredients, sometimes in addition to chlorine, including surfactants and fungicidal components.

For comparison: how different methods work

Methods/Means	Kills fungus on the surface	Penetrates into pores	Prevents regrowth	Chemical risk
Ayudin Antihongos	✔	Partially	✔ Average	Average
Chlorine (lavandin)	✔ Good on tiles	✘ Bad	✘ Low	High
Vinegar (natural)	✔ Good	✔ Better than chlorine	✔ Average	✔ Low
Hydrogen peroxide	✔ Yes	✔ Yes	✔ Average	Average
A general purpose cleaner	✘ No	✘ No	✘ No	✔ Low

This table shows a general comparison of important parameters: what works best on different surfaces and with different intensities of fungus.

Practical Recipes: How to Use Ayudin Antihongos and Other Remedies

Recipe #1 - Quick Tile and Shower Treatment

Ingredients:

Ayudin Antihongos
Gloves and safety glasses
Sponge or brush

How to do:

Put on protection.
Spray the product evenly onto the contaminated surface.
Let it sit for 7-10 minutes to allow the ingredients to penetrate the mold.
Rub with a brush and rinse with water.

Repeat weekly for prevention, especially in humid areas.

Recipe #2 – Deep Treatment with Hydrogen Peroxide (if the problem is severe)

Ingredients:

3% hydrogen peroxide
Spray
Brush

How to do:

Spray peroxide on the affected area.
Give it 10-15 minutes to react with the fungus.
Clean with a brush and wipe with a damp cloth.
If necessary, use Ayudin Antohongos afterwards for additional disinfection.

Recipe #3 – Homemade Vinegar Spray (Eco-Friendly, Gentle Option)

Ingredients:

White vinegar
Spray

How to do:

Fill a spray bottle with pure vinegar (undiluted).
Spray onto surface, let soak in for 60 minutes.
Wipe and add another pass if necessary.

Vinegar works well where mould is just starting to appear or on sensitive surfaces.

Safety tips for working with antifungal products

Always wear protective gloves and glasses.
Ensure good ventilation of the area when working with chemicals.
Do not mix different household chemicals (such as bleach with acids) as this may produce toxic gases.
Follow the manufacturer's instructions on the package.

In conclusion, Ayudin Antihongos is a reliable product for the regular fight against fungus and mould on household surfaces thanks to its combined action: it not only removes visible traces, but also reduces the number of live spores and stops their development.

For comprehensive control of the problem, combine it with other methods (vinegar, peroxide), especially if the fungus is deep-seated or on porous surfaces.
