With the amount of work that is undertaken during a bathroom renovation, it can sometimes be necessary to remove silicone caulk that has inadvertently been left on your tiles. Following a few steps to remove the deposits will ensure that your tiles remain clear.

Step 1 - Inspect

Whether silicone caulk has been used to seal the bathroom tiles or some excess remains after renovation work, you should begin by examining the entire area so that you are aware of the full extent that needs to be removed. This examination will also help you to determine the amount of work that is required.

Step 2 - Prepare

Prepare the surface for the task by cleaning the space surrounding the silicone caulk with a cloth dampened with rubbing alcohol. After this, thoroughly dry the surface with a cloth. Depending on the position of the caulk to be removed, you may require a glove for your non-dominant hand to provide some friction to keep yourself stable.

Step 3 - Cut Caulk

Using a carpet knife or a razor blade, you will need to cut the silicone caulk away from the wall – the former will be safer to use than the latter. If possible, keep your non-dominant hand out of the way to prevent an accident in case the knife slips. Carefully run the blade along the edges of the caulk where it meets the tile, taking care not to scratch the surface. For irregular shaped deposits, try to follow the shape of the circumference as best as possible and for straight edges, steadily run the blade along the line. Large volumes of caulk may also require you to score a vertical line through the middle of it to enable it to be removed more easily.

Step 4 - Remove Caulk

Where the silicone caulk failed to fall away easily after being cut, work the tip of a putty knife into the freshly cut gap at the edge to pry it away from the wall. If the size permits, grip the loosened edge of the caulk and use the putty knife to continue levering the substance away until you can remove it completely. Undertake this process gradually to ensure that you remove as much of the substance as possible, without causing damage to the tiles beneath.

Step 5 - Clear Traces

The nature of caulk means that it is a hardy one that will not give way easily. As a result, you may find that traces remaining on the tiles after you have removed the excess. Rather than risk scraping the tiles with a knife or razor, begin by using a scraper and laying the blade at a 45-degree angle on the tile and smoothly scraping the surface. Follow this by scrubbing the surface with a cloth that has been dampened with alcohol. If this fails to remove all traces completely, scrape the surface again and continue to alternate until all the caulk has disappeared.
