Introduction
This guide shows how to safely remove an old silicone seal that needs replacing from a glass show door. The seal is prone to moisture and may result in mold over time. When mold is present, like in the picture shown, it would create a very disturbing build up of fungi that is extremely harmful in the air and to see in a shower. The visible black spots of mold that can’t be removed through cleaning chemical and it must be replaced due to safety concerns. Most of the tools used here would need to be purchased from a hardware store and are not common household items. Make sure to be very careful with the glass and not damage either the tub or glass with the tools. While using a knife always be cautious and safe, wearing utility gloves may help.
