Jelmar CLR PRO CL4PROEA Calcium, Lime and Rust Remover, 28 oz Bottle

Great for hard stains due to hard water and the seller was great at working together to make sure order was not only received but kept me updated. Thank you

This is by far the best product for calcium and rust build removal up with regards to plumbing

Good product that helps remove or dissolve calcium, lime and rust. I have used this before and I am going to try it on the heater core of my truck and let it soak overnight, then flush it. I’m hoping it just may have a calcium buildup that I can break down and flush out.

Great on hardwater clean up.

Excelente gracias

We have lots of iron in our water, the CLR dissolves the stains well

I live in Los Angeles, where we have hard water. And the hard water clogs up the "jets" in my toilet bowl, meaning it can take several flushes to get rid of the contents of the bowl. CLR (and an Allen wrench or other tool to dislodge the mineral buildup) is super effective in helping to reduce the blockages and return my toilet to proper functioning. I should probably do a quarterly maintenance treatment to keep it in optimum condition, but I'm also lazy and don't have a great deal of interest in messing with my toilet unless absolutely necessary.

It works. Thank you so much

När en vara försvinner behöver man info och kommunikation. Det enda jag fick till svar efter massvis av eftersökning var "-har kanske kommit bort?" Ingen alls återkoppling.

Doesn’t remove rust
