What Removes Caulk?

Caulk needs to be removed and replaced every few years to ensure a quality seal and avoid mold accumulation.

Caulk can become moldy or begin to lose its sealant properties as it ages. In the case that the caulk can not be cleaned or bleached, it will need to be removed and replaced. Removing caulk is a fairly simple procedure, but needs to be done thoroughly and completely in order for the next application of caulk to bond correctly.

Caulk Remover

A chemical caulk remover should be applied to the surface first. Caulk removers come from a variety of manufacturers and can be applied straight from the bottle or using a brush or rag. This chemical will help to soften the caulk for easier removal.

Slicing

Use a painter's five-in-one tool to hook an edge into the line of caulk, and try to pull up and remove it in a solid strip. A razor can also be used to split the line of caulk, allowing you to get a better grip on each side. Pulling the caulk up in large continuous strips will save time and effort in the long run.

Needlenose Pliers

Excess caulk that remains along the edges can be pulled up using needlenose pliers. Care must be taken not to damage tiles or the surrounding surfaces.

Warning

Do not use cleaners containing ammonia to remove trace amounts of caulk. Ammonia gives off poisonous gases when mixed with the chemicals in a new line of caulk or trace amounts of the old caulk.
