Removing decorators caulk is an important skill that every DIYer and tradesperson should know how to do, it is arguably equally as important as knowing how to correctly apply caulk. Below we have listed some key steps and tips to ensure the caulk is removed effectively every single time.

Caulk should be replaced once any signs of wear and tear or damage start to appear, as it will only degrade further and eventually just be ineffective. Prior to applying a new, replacement caulk you’ll need to thoroughly remove any existing caulk and its residue.

Preparing the Surface

Before removing the caulk it is important to clean the area with warm soapy water and then dry thoroughly.

Softening the Caulk

Before cutting away at the caulk, you should try to soften it as much as possible, as this will make it easier to remove. You can either use a commercial caulk remover/a vinegar based solution/ or some rubbing alcohol. Your chosen product should be applied to the caulk surface and left to sit for several hours. You can also use a hairdryer in bursts of around 30-40 seconds to heat and soften the caulk.

Removing the Caulk

Using a utility knife, run the blade along the edge of the caulk line, getting under the old caulk and levering it up. The larger sections of the caulk should then begin to peel away.

Once you have removed as much as possible using the utility knife, you should then wash the area again with warm soapy water and thoroughly dry. Then take either your commercial caulk remover or rubbing alcohol on a cloth and apply to the remaining residue, which can then be wiped away. If there are still any remaining pieces of caulk, you should then take some pliers to peel those pieces away. 

Cleaning the Area

Rinse the area thoroughly with warm soapy water and dry thoroughly. You can now apply new caulk to the surface, however it must be completely dry prior to application.
