Learn About Hard Water
Learn About Rust & Iron
A map of the US shows water hardness levels by region, ranging from slightly hard to extremely hard, using different shades of green and white—valuable for choosing the right cleaning products.

Where Hard Water Hits Hardest

Hard water is water with high mineral content—especially calcium and magnesium—and its prevalence varies across the U.S., as shown in this heat map.
The harder your water, the more likely it is to leave behind mineral deposits on surfaces like faucets, shower doors, and tile. Over time, this buildup can lead to stubborn limescale stains and reduce the efficiency of appliances that use water.

Mapping the Source of Rust Stains

This heat map highlights regions with higher iron content in the soil, which often translates to higher iron levels in groundwater.
When iron-rich water is used in your home, it can leave reddish-brown rust stains on sinks, tubs, toilets, and even exterior surfaces. Homes in areas with high soil iron may see more frequent or severe staining, especially around water fixtures and outdoor irrigation.

Clean without compromise

Strong on the toughest cleaning jobs, gentle on your surfaces, your family, and the planet.

How to Clean a Kitchen Sink

CLR Mold & Mildew Stain Remover. Outstanding product. Used it on my bathroom ceiling and it totally took out the mold, with very little effort on my part. I also used it on my
kitchen & vinyl floor (which was a basket case). The floor now looks like it is brand new. The key is to follow the instructions and leave it sit for 10 minutes before wiping. I could not be happier. I will recommend this product to all my friends. Keep up the great work.

Just purchased your CLR Brilliant Bath and couldn’t be happier with my shiny
clean bathroom. I’m new to CLR products, but you now have a convert! Plan to share the good news with all my friends cuz who doesn’t want shiny clean with half the work? YAY! Also delighted to see that the company is women owned! Total win-win. Thanks

1949

Manny Gutterman founds Manny Gutterman & Associates Inc.

as a national sales representative organization, dedicated to selling all types of proprietary products to chain drug, variety, hardware and department stores and also establishing an ethical and reliable channel for "close-out" merchandise.

1960s

Jelmar, LLC, CLR Brands’ parent company, is founded

A friend in advertising asked Manny to sell a warehouse full of cleaning product in barter from a bankrupt client. Of course he accepted the challenge. Manny – along with sons Steven and Arthur – reformulated and repackaged the abandoned product and sold it as Tarn-X® Tarnish Remover.

1980s

Calcium, Lime, and Rust Remover is developed

Manny, Arthur and Steven were meeting with business partner Al Eicoff to develop a product that could serve as a complement to Tarn-X. A powerful lime and rust remover was developed. And after some struggles to find a name for the product, Calcium, Lime & Rust Remover was born.
