Why has mold returned after using ProtoxHysan?

ProtoxHysan is a disinfectant – i.e. the product kills the mold and washes the surface. But since ProtoxHysan does not leave any residues of the active substance, the product has no preventive effect.

If there is a risk of the mold coming back, then a preventive treatment should also be carried out ProtoxProtect after cleansing with ProtoxHysan. In addition, the moisture source should be identified and removed before the mold attack is combated.
