30 Down-and-Dirty Tricks for Big DIY Savings

Dissolve mineral deposits plugging up your showerhead rather than replacing the fixture. Remove the head, soak it overnight in a 50-50 vinegar-and-water solution, flush it out, then reinstall it to improve water flow. If the showerhead is too hard to remove, fill a plastic bag with solution and secure it around the head with rubber bands.

Cost: $2 for white vinegar.

Savings: $20 or more for a new showerhead.

Bonus: This also works on clogged sink aerators.
