How do you remove heavy soap scum?
How do you remove heavy soap scum? Sprinkle a large amount of baking soda on a cloth or sponge, dampen and scrub. For tougher soap scum build up, you can also try making a paste out of baking soda and vinegar. Let the paste sit on the stain and then scrub. The acidity in the vinegar will help break down the scum.
