Silicone King recommend cleaning of the silicone at least as frequently as once a week using a damp cloth and a cream cleaner such as “CIF” using a light rubbing action and then rinse off. Avoid the use of spray cleaners as these contain chemicals that may have a detrimental effect on the anti mould properties of the silicone sealant and may even discolour the sealant – if this was the case Silicone King would have no liability.
