Clean sinks and bathtubs

Put the shine back in your porcelain sinks and bathtubs by giving them a good scrubbing with full-strength white vinegar, followed by a rinse of clean cold water. To remove hard-water stains from your tub, pour in 3 cups white vinegar under running hot tap water. Let the tub fill up over the stains and allow it to soak for four hours. When the water drains out, you should be able to easily scrub off the stains.
