Project Overview

You can freshen up your whole bathroom just by removing silicone that’s discoloured, stained or untidy. We show you how to cut and scrape out the old silicone. Plus, how to take off any residue so the surface is clean and ready for resealing.
Continue to step-by-step instructions

Step by Step Instructions

1 Cut along where the silicone joins the wall
2 Scrape inside the gap
3 Wipe the surfaces clean
  • Step 1. Cut along where the silicone joins the wall

    Use a sharp knife and cut along the silicone, running the metal blade along the wall. Then gently run a flat-blade chisel against the tiles so the silicone pops out.
  • Step 2. Scrape inside the gap

    Use a flexible plastic or metal blade to scrape out the deeper silicone. Push and pull the blade backwards and forwards between the gap. The silicone will grip the surface of the blade and start to come loose. 
  • Step 3. Wipe the surfaces clean

    Once you have removed most of the silicone, wipe the remnants off using a cloth. You can make the job a bit eaiser by soaking the cloth in methylated spirits. The methylated spirits act as a solvent, breaking down the last of the silicone, making it less sticky and easier to wipe up.
