How to Remove Old Bath Sealant
Softening the old sealant makes it easier to remove. (bathroom image by Vonora from

Bath sealant, also known as caulking, is used to seal areas around tubs or sinks. Normally the sealant is applied next to the wall and the bath fixture so moisture does not seep through and develop mould. After several years, the sealant dries and tends to crack and shrivel. The old caulking must be removed and replaced. Removing the sealant is not hard once you know the proper procedure.

  1. 1

    Place warm, wet rags over the caulk to soften it. Allow the rags to remain on the sealant for five minutes.

  2. 2

    Remove the rags and slice under one end of the sealant with a utility knife. Stick your finger under the pried-up area and begin to pull the sealant away from the wall.

  3. 3

    Pull the sealant slowly and gently. Keep placing a finger under the sealant as you pull it away from the surface. This helps keep the sealant from breaking as you pull.

  4. 4

    Remove any leftover spots of sealant with needle-nose pliers. Grasp the specks of sealant with the pliers and pull gently.

  5. 5

    Wipe the area with a clean rag to remove any sealant residue still clinging to the surface.

Tips and warnings

  • Replace the sealant as soon as possible to keep moisture from settling behind the bath fixture.
  • You may also use a caulk remover to aid in removing old bath sealant.
