1. Use bubble wrap to prevent toilet-tank condensation
If your toilet tank sweats in warm, humid weather, bubble wrap could be just the right antiperspirant. Lining the inside of the tank with bubble wrap will keep the outside of the tank from getting cold and causing condensation when it comes in contact with warm, moist air. To line the tank, shut off the supply valve under the tank and flush to drain the tank. Then wipe the inside walls clean and dry. Use silicone sealant to glue appropriate-sized pieces of bubble wrap to the major flat surfaces.
