Lime scale is a white, alkaline residue formed from the minerals in hard water that can build up on shower doors, tubs and fixtures. This substance can be wiped off surfaces when it is broken down with an acid. Many bathroom cleaners have acid in their formulas, but they release harmful fumes that may cause some people respiratory distress, especially those with lung ailments. All-natural white vinegar has no dangerous fumes and contains acetic acid, which cuts through the lime scale for easy cleaning.
Pour white vinegar into an empty spray bottle.
Set the nozzle to the spray setting so that it will emit a mist.
Step inside the shower and close the doors so that the both sections are accessible. Thoroughly spray the doors so they are soaked with the vinegar. Also spray the metal parts of the doors and in between the framework and the glass.
Place paper towels on the wet shower doors so that they stick to the doors, if there is a lot of build-up. Cover the shower doors completely with the paper towels. Let the vinegar soak in for 30 minutes.
Remove the paper towels and wipe the shower doors down with a clean, dry cloth. Repeat this process if necessary for especially stubborn stains.
Cleaning shower doors with white vinegar once a week will keep lime scale from building up and becoming thick and noticeable. Let shower doors soak for 1 hour if the stains are especially thick. Lime scale makes bathroom fixtures appear dingy and cloudy. Soak the fixtures with white vinegar, let it soak in, and then wipe them down so that they are shiny again.
