Remove Silicone Caulk From Glass Remove Silicone Caulk From Glass
The use of silicone caulk as a sealant can result in traces of the substance accidentally coming into contact with the glass and remaining there to harden. Follow the steps below to easily remove the caulk and return the glass to its original state.
Step 1 – Inspection
Examine the entire pane or sheet of glass to locate every point from which silicone caulk needs to be removed. If necessary, stick a small piece of masking tape next to each instance so that you do not lose track of it. This inspection will also help you to determine how much work will be required to complete the job.
Step 2 – Remove Excess
Depending on how firmly the silicone caulk is fixed in place, you may be able to remove most of it with either a scraper or a razor blade. If you have both, begin by using the scraper as it will be safer and easier to use. Position the center of the blade against the base of the caulk where it meets the glass. Attempt to cut the caulk away by firmly applying some pressure while holding the scraper at a 45-degree angle. If this does not work or only removes the excess, carefully make use of a razor in the same way as the scraper. To enable it to be gripped properly and safely, it should have a casing on one edge.
Step 3 – Apply Heat
If the silicone caulk proves difficult to remove and you are concerned about the risk of scraping the glass, make the job easier by first applying some heat. Though a hot air gun can be rented from a tool hire company, a hairdryer may prove just as useful for the task. Set on high heat then point the nozzle of the hairdryer onto the caulk for a few moments before using a scraper to test whether it has softened. If the substance gives easily, continue with the scraping process to remove it.
Step 4 – Remove Traces
Whether there were remnants from previous caulk on the glass or some of the material remains after the excess has been removed, you may find it necessary to undertake further cleaning work to remove it. Begin by applying some heat and scraping away as much of the caulk as possible, thereafter dampen a sponge with some rubbing alcohol or mineral spirit and wipe the affected section of the glass. This will help to melt the caulk so that you can make the remainder easier to scrape away. If the glass remains cloudy, use a cloth dampened with alcohol to rub the glass with to clean it.
Finish the task of cleaning the glass with some household soap dissolved in water and a clean cloth. Rinse the glass with clean water before drying it thoroughly.
