While 30 Seconds Cleaner should not remove a sealant on a deck, it could potentially remove a stain. Per the product label, you should always test an inconspicuous area first to check for any potential bleaching or other discoloration. If you are needing to clean and seal a deck, then we recommend using the cleaner first to remove and stains, mildew, etc. before applying a sealant.
