Remove mineral deposits from shower heads

Wash away blockages and mineral deposits from removable shower heads by placing them in 1 quart (1 liter) boiling water with 1/2 cup distilled vinegar for 10 minutes (use hot, not boiling, liquid for plastic shower heads). When you remove it from the solution, the obstructions should be gone. If you have a non removable shower head, fill a small plastic bag half full with vinegar and tape it over the fixture. Let it sit for about 1 hour, then remove the bag and wipe off any remaining vinegar from the shower head.
