Safe for use on a wide range of surfaces including glassware, tile, metal, and all plumbing types, it features a non-toxic, alcohol and bleach-free formula. Highly rated with 4.6 stars from nearly 3,000 reviews, it’s the go-to solution for maintaining spotless, clog-free fixtures in homes and commercial spaces alike.

## 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.

## 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.
