## Overview

Jelmar CLR PRO CL4PROEA is a powerful 28 oz calcium, lime, and rust remover designed to dissolve the toughest mineral buildup on a wide range of surfaces including glassware, tiles, coffee pots, tubs, toilets, and sinks. Its safe, phosphate-free formula protects all plumbing types while effectively blasting rust stains from metal, porcelain, and brick. Highly rated and trusted, it’s the go-to solution for maintaining pristine, clog-free fixtures in hard water areas.

## Description

Powerful multi-use cleaner dissolves even the hardest buildup. Blasts deposits from stainless steel, glassware, tile, glass and fiberglass, tea and coffee pots, humidifiers, tubs, toilets and sinks. Zaps rust stains from stucco, brick, porcelain, chrome and metal. Descaling formula contains no alcohol, ammonia, bleach or phosphates.

Review: Effective and (unfortunately) necessary - 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.
Review: Good Stuff - Worked like a charm

## Questions & Answers

**Q: Will clr hurt you?**
A: We have used CLR for several years and have had no reaction on or hands or rags we have used to get rid of surplus or build up of lime deposit in our sinks, bath, and shower. We have had it on our hands but washed them as soon as we were through cleaning. We are still using it.

**Q: Can I use this on rusty tools?**
A: I think you can use it on rusty tools.  I would think you need to soak the tools in it.  I guess it depends on how bad the rust is.  I think it's worth trying.

**Q: How to clean efflorescence from brick**
A: try muriatic acid. be sure you use the directions before.

**Q: But what is it? Ingredients?**
A: This should work on shower heads.
