Soap scum can quickly build and create layers of greasy film on the exterior walls and floor of your bathtub. The old soap holds dirt, oils, hair and other debris that dull the polish of the bathtub. This makes bathing and relaxing in the tub less appealing because the tub doesn't feel clean and water becomes cloudy from the soap residue. Thankfully, you can keep your bathtub fresh and free of soap scum by using the right tools and periodically cleaning your tub and shower to prevent build up from happening.
Turn the shower on at the hottest level and close the door, so humidity can build in the room. Spray the entire bathtub heavily with water and spray it with a tub and tile cleaner to begin loosening the soap scum. Let the chemicals sink into the tub for five or more minutes and then come back in the room.
Scrub the bathtub in circular motions with a cellulose scrub sponge. Rinse with water after scrubbing and touch up spots that you missed. You may need to use a more abrasive cleaner also if the soap scum is old, thick and hard. Rinse the tub out again and prepare to use a different cleaner if the first cleanser doesn't loosen all the soap scum.
Sprinkle baking soda or an abrasive cleanser on the sides and bottom of the bathtub. Spray a mist of water in the shower to create moisture and then turn it off.
Scrub the bathtub again in circular motions with a rough scrub brush. Rinse and repeat to loosen and wash way soap scum. Rinse the tub again until all the baking soda or abrasive cleaner goes down the drain.
Place an eraser scrubber pad under the water to wet it and scrub the eraser in circular motions throughout the tub until all the soap scum dissipates. Continually rinse the tub as you clean to wash away residue.
