How can Pure Wall be more effective than Ayudín?

1. Deep penetration into porous surfaces (root destruction): The sodium hypochlorite in Ayudín has high surface tension, preventing it from penetrating deeply into plaster, gypsum, or brick walls. When applied, it only removes the visible stain, but the water-based solution penetrates the pores and feeds the deep roots of fungi ( hyphae ). Pure Wall contains penetrating surfactants that reach wet plaster layers without artificially whitening.

2. Residual effect and prevention: The chlorine in Ayudín works through immediate oxidation and evaporates quickly, leaving the surface vulnerable to new mold spores within a few days. Pure Wall contains a fungistatic agent that remains in the material and inhibits mold recurrence for a long time.

3. Protecting paint and interior finishes: Using bleach or Ayudín on latex-painted walls often results in white haloes, stains, or peeling paint. Pure Wall is specifically designed for cleaning living areas (bedrooms, living rooms) without damaging existing finishes.

When is it better to choose Ayudín Antihongos?

• Non-porous surfaces and fast disinfection in the bathroom: Ayudín's oxidizing power is unmatched on tiles, glass partitions, silicone sealants, and plumbing fixtures. It removes black pigment in minutes and kills 99.9% of bacteria.

• Cost-effective for regular maintenance: Thanks to its low price, Ayudín remains an excellent budget-friendly choice for weekly or bi-weekly cleaning of wet areas.

Conclusion and professional recommendations

There is no universal remedy for all occasions:

• Choose Pure Wall if you need to eliminate mold on painted walls, ceilings, drywall, or interior plaster . Although more expensive, it will save you from having to repaint your walls and prevent mold from growing back from the inside.

• Choose Ayudín Antihongos for direct cleaning of bathrooms, tiles, grout, and fixtures where you need instant stain removal and cost-effective disinfection.
