If you have glass shower doors you know how soap just loves to stick to them. Clean them easily with a sponge dampened in white vinegar. Also pour full strength vinegar into the track that holds the glass panels. Let the vinegar soak in for a few minutes, then rinse to completely to remove mold and soap scum. To keep your shower doors cleaner and to give a new shine to fiberglass doors apply a light coat of acrylic floor finish.
