When I moved in there is bathtub fitted cover modular plastic piece which has yellow buildup in certain spots. I have tried soaking in bleach, baking soda, vinegar, lime and rust products, bathroom cleaning products, and scrubbing. Nothing works. Perhaps someone who had one of these installed new in their home an recommend a product the installers suggested to use to prevent this from happening. Many thanks.

Contact bath fitters....they have a compound that they can apply for you.
If your tub has been done by a very very popular company, then you have a warranty for LIFE! I’ve had one bathroom tub done by a fantastic company and I can call them to come in if there are any problems. They don’t charge for the visit.
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 Karen,
My name is Linda and I'm wondering if you've tried hydrogen peroxide and cream of tartar? That combination is recommended for removing the yellow for fiberglass so maybe it will work with what you have. I hope this helps you. Wishing you success.

It is very likely not yellowing but instead Rusting. Likely due to metals in the water which became embedded in the Tub over years. It looks yellow rather than brown because of the materials and environment.
Some people get fashionable green stains...
Although you can sometimes scrub out rust, rarely does this scrubbing Get rid of all the Residues and Stains that rust leaves behind.
So, scrubbing your arm off is futile.
I can only imagine how it was. It is likely at the best State it has been in years, possibly decades, and the best state it will be, until you fix it Right.
To fix that Right you need something like:
Rustoleum Tub and Tile Repair Kit
which is available mostly anywhere Rustoleum is Sold including Home Depot and Lowe's.
Since you have used anti-rust products and had no luck. You could use Krud Kutter, it worked on our tub/shower.
