Distilled White Vinegar
Distilled white vinegar is mildly acidic, which makes it an excellent all-natural soap scum remover. The acids in distilled white vinegar dissolve the mineral and soap buildup that create soap scum so that the film is easily wiped away. To use distilled white vinegar as a soap scum remover, either apply it directly to the soap scum or mix equal parts distilled white vinegar and water in a squirt bottle. Spray the vinegar or vinegar solution onto the soap scum from the bottle. Wipe away the film using a cleaning cloth or paper towels.
If you find the scent of white vinegar unappealing, try using lemon juice on your soap scum problem instead. Lemon juice is just as acidic as distilled white vinegar and works just as well for removing soap scum. The difference is that lemon juice has a citrus smell that some find more pleasant than vinegar. Another difference is cost; lemon juice is more expensive than white vinegar. Use lemon juice in the same way you would use vinegar, by spraying directly onto soap scum or by mixing equal parts lemon juice and water and spraying that onto soap scum. (Diluting the lemon juice with water will help with the more expensive cost of the juice as you will use less juice to clean this way.)
Rubbing alcohol, also known as isopropyl alcohol, is used in many commercial cleaning solutions. This alcohol is useful for cleaning soap scum from glass as well as tile surfaces. Try combining 1 cup of rubbing alcohol with 1 cup water and 1 tbsp. white vinegar in a spray bottle. Spray this mixture onto any surface affected by soap scum, then wipe with a cleaning cloth or paper towels. Using alcohol removes soap scum and gives you the peace of mind knowing that no harmful chemicals were used to clean your bathroom.
