Need NUCLEAR WASTE!

[StoneyReef]

I need something as strong as nuclear waste to remove the soap scum in my bathtub. I have tried it all, CLR, clean shower, etc etc, Nothing will remove it!!!!! It is kinda gross have a 1/4" thick ring of black crud you can literally scrape!


Anyhow, Give me some ideas. It is a cream colored fiberglass all in one piece tube that has the high sides, what is it called tub around or something, Anyhow give me some ideas on industrial strength chemicals that will remove this stuff, but not harm the tub!

It is called a Tub Surround.
Go to your local Janitorial/ Chemical store, ad tell them the problem, they will hook you up with the Good Stuff. If they don't PM me I will check on the name of it here. We used it at our Store.
