How to Remove Silicone Sealant from Around a Bath


Silicone sealant is commonly used to create a watertight seal around various fixtures, including bathtubs. Over time, however, this sealant can deteriorate, become discolored, or develop mold and mildew. When this happens, it is important to remove the old sealant and replace it with fresh silicone to maintain the integrity of the bath. In this article, we will guide you through the process of removing silicone sealant from around a bath, providing step-by-step instructions and helpful tips along the way.

Materials and Tools You Will Need:

Before you begin the task of removing silicone sealant from around your bath, gather the following materials and tools:

- Razor blade or scraper

- Silicone sealant remover (commercial product or methylated spirits)

- Soft cloth or sponge

- Bucket of warm water

- Mild detergent

- Rubbing alcohol

- Paper towels

- Safety goggles

- Gloves (optional)

Preparing the Area:

To ensure a smooth and efficient sealing removal process, it is crucial to prepare the area around the bath. Start by thoroughly cleaning the bathtub and its surrounding tiles. Remove any obvious dirt or grime using warm water and mild detergent, and scrub the surface gently. Rinse the area with clean water and dry it completely. This will prevent any leftover debris or residue from interfering with the removal and reapplication of silicone sealant.

Softening and Loosening the Sealant:

Before tackling the old sealant, it's helpful to soften it first, making it easier to remove. There are two primary methods for softening silicone sealant: commercial sealant removers and methylated spirits. If you opt for a commercial product, follow the instructions provided by the manufacturer. Alternatively, dip a clean cloth or sponge into methylated spirits and apply it directly to the sealant. Let it sit for around 20 minutes, allowing the spirit to penetrate and soften the sealant.

Removing the Old Sealant:

Once the sealant has softened, it's time to remove it. Wear safety goggles to protect your eyes, and consider using gloves to shield your hands. Start by using a razor blade or scraper at a 45-degree angle to gently scrape away the softened sealant. Be cautious not to scratch the surface of the bath or surrounding tiles. Continue scraping until the majority of the old sealant has been removed. For stubborn pieces that won't budge, use rubbing alcohol on a cloth to break them down further. Repeat the process until all traces of the old sealant are gone.

Cleaning and Prepping for the New Sealant:

After removing the old sealant, thoroughly clean the area to ensure optimal adhesion for the new silicone. Dampen a cloth or sponge with rubbing alcohol and wipe down the exposed surface, eliminating any remaining residue and grease. Pay attention to hard-to-reach areas, such as corners and edges. Once cleaned, allow the surface to dry completely before applying the fresh silicone sealant. Moisture can hinder the effectiveness of the new sealant, so be patient and double-check that the area is entirely dry.


By following these step-by-step instructions, you can successfully remove silicone sealant from around your bath, preparing it for a fresh application. Regular maintenance and replacement of silicone sealant will ensure a watertight seal, prevent mold growth, and maintain the overall cleanliness of your bathing area. Remember to exercise caution, use the appropriate tools and materials, and take your time during the removal process to achieve the best results.
