Can this product be used on an above ground pool liner?

Our metal pool ladder rusted and has stained the bottom of the pool. I just want to make sure it will not eat through the vinyl liner.

Our guest bathroom had a nasty two foot blue green bathtub stain from a shower drip that took many years to build up without us noticing. Conventional cleaning products did nothing. The directions say soak and rinse a diluted solution in 60 seconds, but it took a full strength soak of over an hour on a paper towel to remove the stain. And it worked! Great stuff, but it may take a lot more time and solvent than indicated on the bottle.

This product did a great job of removing the build up from fixtures around my house. You do have to be careful to unsure that it doesn't sit on natural stone materials as it can etch the surface, so be aware of this prior to using it. Overall it worked great.

The water heater control failed because of the mud and scale that leaked into the water heater. This product dissolved the sediment and I flushed the tank.

I plugged the tub, poured the entire gallon into the tub, and filled the tub with water; in about an hour, the tub looked brand new.

Rated 5 out of 5 by from Product Review This product was purchased as an alternative to CLR. Typically it is used as an additive to a dishwashing cycle to remove calcium and lime buildup on the inside of the dishwasher and also on clear glass. It works every bit as well as CLR.

We have lime in our water and I need it to clean the toilets. I pour about a cup in the toilet bowl and let it sit for an hour, the toilet practically cleans itself!
