Remove Shower Door Stains
Over time, glass shower doors can become filthy. Soap scum and other bathroom goods like body wash and shampoo can be difficult to get rid of. Hard water deposits are infamous for being difficult to remove.

Once again, WD-40 comes to the rescue! Its water-displacing characteristics make it ideal for cleaning those hard-to-reach shower doors. Simply open the shower door and lightly treat the entire surface with WD-40. Allow for a few minutes for the product to dry before wiping it away with a clean cloth. Depending on how much buildup is on your shower door, you may need to repeat this step a few times.
