How do you get hard water stains off of tub sinks and outside?

product is called CLR...removes Calcium, Lime and Rust...hence CLR...stinks bad so have ventillation

toothpaste.

I make a spray cleaner out of equal parts of cheap bottled lemon juice and vinegar. I add a few squirts of dishwashing liquid, It works great on just about everything, as long as it is wiped off or rinsed. If your the stains are old, put it in a kitchen scrubby handle dispenser, and wipe all over the tub. Let sit a few minutes and rinse with hot water.

If you prefer to buy a ready made cleaner, Scrubbing Bubbles aerosol cleaner is great, even on concrete.

Use CLR . Or soak paper towels in vinegar and let sit overnite. Just rinse and wipe next day. Don't use on grout, it will dissolve.

Toothpaste has worked for me too! Good luck!

Scum Bum by The Clean Team! Green and it works like nothing else I've ever used. Not for use on stone. If you have fiberglass, they have a fiberglass cleaner that takes off everything, so easily. Highly recommended. It has changed my life!
