How do I get "yellowing" off of a mobile home bathtub?

I tried krud kutter(?) On an old blue tub that was abandoned. New!

Step 1

Fill a spray bottle with 3-percent hydrogen peroxide, which is found in drugstores or convenience stores for a minimal price.

Step 2

Move the shower curtain and any fabric items such as bath mats, towels and washcloths, into a safe location. Hydrogen peroxide whitens your tub, and it will also bleach fabric.

Step 3

Remove any bathing or showering supplies such as shampoo, soap and shower caddies from your bathtub area.

Step 4

Rinse the inside of the tub to get rid of any particles, hair or dirt. If there is any visible soap scum, scrub using a non-abrasive sponge with a standard soap scum remover formulated for plastic surfaces. Follow the instructions carefully.

Step 5

Rinse the inside of the tub to remove any cleaner, if necessary. Spray the entire inside of the tub with the hydrogen peroxide. Let the solution soak for 10 to 15 minutes.

Step 6

Wipe the inside of the tub with a wet, clean non-abrasive sponge. If more whitening is needed, repeat Steps 5 and 6 until the yellowing is completely removed.

Hi Sonja,

My name is Linda. You can also use hydrogen peroxide and cream of tartar if it's fiberglass. Those will bleach the yellow coloring. Here's an article that explains how to use them. Wishing you the best.

Sonja, Fiberglass is a material that chemically turns yellow with age. I've never found anything that will whiten it. If you CAN clean it that would be the easiest way to go. If the cleaning fails, follow the directions this guy has given in his popular video. You don't need to rent a paint sprayer with his method, and he also shows you the things that can go wrong.

Use Krud Kutter, it will work very well on ours.
