How to Remove Sealant From Glazed Tile That Has Dried
- 1). Put on a pair of heavy work gloves and a face mask. This will protect you from cuts and fumes. If possible, open any windows in the area where you will be working to increase ventilation.
- 2). Scrape away the silicone sealant or caulk from between the tiles or on the surface of the tiles with a painter's scraper. Avoid gouging or scratching the tiles by working slowly.
- 3). Fill a small bowl with oven cleaner or acetone. Use acetone if you want to remove a non-silicone sealant. If you want to remove a silicone sealant, which is much more difficult to remove, fill the bowl with an alkaline-based oven cleaner.
- 4). Wet a small cotton pad with the cleaner and gently dab it on the remaining sealant.
- 5). Wait for up to an hour for the sealant to soften.
- 6). Scrape the rest of the sealant away with the scraper.
- 7). Wash the tiles with mild dish soap, rinse them to make sure that all of the sealant is gone and allow the tiles to air dry.
