Does this work in bathroom tubs and toliets ?

Absolutely. It works great on bathtub rust stains, toilets, calcium deposits, sprinkler rust stains on the sides of house or sidewalk etc. Spray on and give it a moment to work. The stain should be gone before you rinse it away. Wiping or scrubbing is usually not required unless the rust is super thick. This is marine strength formula and not watered down.

will this work on a fiberglass inground pool?

It should work on a fiberglass pool liner. I used it on plastic, outdoor chairs and a plastic boat (HDPE). I also used it on concrete. It’s best to spray the rusted area and wait - give the product time to work. Don’t touch it for at least five minutes. If the stain is not gone, it shouldn’t take more than a gentle rub with BLUE Scotchbrite (cousin of Starbrite!) -do not use the green, it will scratch.

Is this product good to use?

Yes, this product is good to use per the directions on the label. Since 1973, Star brite has guaranteed satisfaction with all of our products. Call the toll-free number on the label to speak with our live support team if you have any product questions whatsoever.

Will this work on vinyl boat cushions

It will work on vinyl seat cushions. I have a boat cover that I made using marine vinyl. While cutting metal that was on my trailer, some of the metal dust/fragments landed on the boat cover; I didn’t see them until they left little rust spots. The Star Brite removed all traces of the rust and didn’t discolor the material at all.
