Silicon caulk is used in the installation of vinyl windows. Silicon is water resistant and prevents the escape of warm or cold air from the home. After a few years, you may find that the caulk is peeling or discolouring due to mould. Removing the silicone gives you a fresh surface to reapply caulk and seal the windows again. Inspection of the caulk around the windows should be done every year before turning on the heater.

Apply caulk remover to the caulk by squeezing it out of the bottle onto the silicone. Allow it to sit on the caulk for the time recommended by the manufacturer.

Score the caulk with a utility knife.

Pull any silicone that does not come away from the window with a pair of needle nose pliers.

Remove the remaining scraps of caulk using the hook on a 5-in-1 painter's tool.

Mix one cup bleach into one gallon of water and rub down the exposed surface with a sponge soaked in the mixture. Wear plastic gloves. This removes any mould from the surface.
