KaBi White Mold Soft Removal Spray Mold Remover [Wood, Tatami, Slats, Mattress, Curtains] (300ml)

Main highlights

● Follow the same procedure to remove mold from tatami straw mats and white lace curtains ※Do not use on colored or patterned items as it may cause discoloration For wood, tatami mats, and other materials, as a precaution, perform a patch test by leaving it on for at least 30 minutes in an inconspicuous area to check for any discoloration Furthermore, if you work several times a day or spray a large amount of paint at once, this may cause discoloration, so please make sure that the object is not discolored and if it becomes slightly white, please dry it for several days before resuming
Drying time varies depending on the environment and usage amount, but it generally takes about the same amount of time as it takes for water to dry During that time, please avoid approaching the areas that were worked on and, if possible, move to another room If you direct a fan at it, the drying time can be shortened If the chlorine odor is gone and it dries smoothly, it becomes harmless to humans and animals
Conventional mold removers require rinsing, so they couldn't be used indoors. However, since Mold White Soft Remover evaporates to a harmless level when dried, it can easily remove mold indoors This professional-grade mold remover, used in commercial (pro-spec) settings, is effective against black mold, blue mold, red mold, green mold, and white mold The degree of danger while working and the strength of chlorine smell is less than that of commercial mold removers
About the actual mold removal method: Spray evenly over wood mold No pre-wetting or wiping required Spray the agent directly to prevent mold spores from spreading and causing mold growth in other areas Applying too much can make the chlorine odor harder to remove, so lightly dampening it is sufficient for effective results After spraying, please leave it for 30 minutes If there are still mold residues, spray the affected area again and let it sit for 30 minutes Even for mold from 30 years ago, repeating this process 2 to 4 times will gradually remove it After the mold is gone, wipe it roughly with water and let it dry
