Hard water stains occur when household water has a high mineral content. As water dries on surfaces, it leaves behind minerals that appear white on a surface. Because these mineral stains are unsightly, most people prefer to remove them when they occur. Remove hard water stains from a plastic shower surface with basic household ingredients. This removal process keeps your bathroom surfaces clean and shiny.
Fill the spray bottle with full-strength white vinegar.
Spray the hard water stains on the plastic shower surfaces with the white vinegar to saturate them completely.
Rub the plastic surface with the nylon scrubber to remove the hard water stains.
Assess the plastic surface. If the stains persist, proceed to the next step.
Pour approximately ¼ cup of baking soda into the shallow bowl.
Spray the remaining stains again with the white vinegar.
Dip the nylon scrubber into the baking soda, and apply the baking soda to the vinegar-moistened plastic surface.
Rub the plastic surface with the nylon scrubber to work the baking soda into the vinegar. Continue rubbing until you remove every remaining hard water stain.
Rinse the plastic surface with clear water.
Dry the plastic surface with a towel to finish the cleaning process.
