Essential oils: Wipe scum-covered glass doors or shower curtains with a few drops of lemon oil twice a month. It will protect them from grime buildup.
Vinegar: To combat mineral deposits on showerheads, pour vinegar into a plastic grocery bag and knot the handles over the neck of the showerhead, securing with rubber bands. Let soak overnight. Rinse with water in the morning.
