Any ideas on removing soa stains from shower door?

I have had pretty good luck with Bar Keeper's Friend in liquid form and a green scrub pad. Good luck!

I have had good luck using kaboom. Once the stains are removes use rain X to prevent the return

Hello. I make a paste with baking soda and vinegar and scrub it on. I let it sit for 5-10 minutes then rinse and repeat if necessary. I hope this works for you!

Have you tried a product called Sno Bowl? It's to clean toilet bowls and works great on mineral build up. It's caustic so take care.

Thanks muc!
