Selleys Original Sugar Soap is excellent for cleaning mould and mildew from surfaces both indoors and outdoors before repainting. Whilst Selleys Original Sugar Soap will clean off visible mould, it does not kill the mould spores and therefore if conditions are conducive to mould growth the mould may return.
To help prevent this you can use a bleach or white vinegar solution after cleaning to kill any existing mould spores on the surfaces. We recommend that you apply and then rinse off thoroughly - some safety precautions are required to do this such as wearing disposable gloves and protective eyewear. If repainting an anti-mould additive can be added into your paint to help prevent future mould.
