Hard water stains develop on a number of surfaces, including plastic. When hard water comes into contact with the plastic surface, it dries leaving a cloudy, unattractive film that makes the plastic look unclean. The easiest way to remove the hard water stains is to grab a few items from your cupboard, and begin the stain removal process.

Step 1

Dip the edge of a cleaning cloth into a dish of pure white vinegar. Vinegar will dissolve the marks without damaging the plastic or leaving a residue when dry.

Step 2

Wipe over the hard water stains, using circular buffing motions to get rid of the marks.

Step 3

Dip a toothbrush into the vinegar and scrub hard stains that are not removed with the cloth alone.


Step 4

Soak the plastic overnight in a 50/50 mixture of water and white vinegar for extremely tough stains, if possible.

Step 5

Scrub the plastic with a cloth the following morning, and allow it to air dry.
