Soap scum is a white film that’s a combination of soap, minerals from hard water, and your bodily oils. The unflattering residue makes your bathroom wall, sink, tiles, and glass doors look dirty—especially when it’s deep-seated and built up over the years.
Different from mold, bacteria, and limescale, this layer of dried soap and mineral suds can easily combine with mold and mildew, which becomes hard to remove if left uncleaned. It may also transform in color and smell over months of disregard. But using the right cleaning solutions and steps, you can clean a year’s worth of soap scum from any part of your bathroom.
How to Remove Soap Scum Using Different Cleaners
Removing soap scum can be a challenging task. With these natural ingredients and tools, you can effectively take off these residues and restore the cleanliness of your bathroom surfaces:
Baking Soda and Vinegar
Baking soda is a mildly abrasive substance to scrub away the scum, while white distilled vinegar will help dissolve it as a mild acidic cleaner. You will notice these two ingredients will create a fizz when combined. This helps loosen and dissolve the scum.
- To use, sprinkle baking soda directly on the problem areas.
- Next, spray or pour white vinegar onto the baking soda and let it fizz.
- Let it sit for a few minutes, then scrub the surface using a sponge or a scrub brush.
- Rinse with water to finish.
Vinegar and Dish Detergent,
The combination of white distilled vinegar and dishwashing soap is a powerful combination for a year’s worth of scum.
- In a spray bottle, add equal parts white vinegar and dish detergent.
- Spray on the affected area and let it sit for 15 minutes.
- Scrub the surface and then rinse with water.
