Customer Reviews for CLR 1 Gal. Calcium, Lime and Rust Remover

This product is good for clearing and cleaning the drains for the dishwasher, kitchen and bathroom sinks and even the toilet. We've been using it for a long time and are pleased with the results.

Used this just to pour into the toilet bowl for a few hours and it flushes a lot better.

CLR Is always the right cleaner for heavy lime build up around the sink and toilet. It really works!

Have used this for several years. Works well to soak shower heads and dissolve deposits from the well water.

DON'T WASTE YOUR MONEY. This didn't work at all. I had a smaller container that was a year old that worked great but I needed more so I bought the bigger jug and it was like water it didn't work at all. I don't know if they are watering it down, maybe they changed the formula or it was a defective batch but it was a waste of $25 I'm very disappointed with the product.

Great product use it alot for calcium and lime build up

The product is great!! BUT, the sprayers were shipped WITH the large containers with NO protective packing. TWO of the three sprayer nozzles were damaged beyond repair. Attention to detail is a necessity especially in shipping dissimilar containers.

Product did an excellent job.

I submerged my shower head (22 hrs ) in a bucket with the full container to dissolve the calcium. I believe it’s the calcium causing a wissol in the shower head. Your product didn’t work so I’ll be replacing the shower head ?my unit is 15 yrs old

This product not only cleans our older toilet, but seems to keep the line to the septic tank clear! We hardly ever have a plugged toilet since we started using CLR.

Works excellent on a variety of items.

Great product. Used it to clean a large indoor waterfall clogged from hard water residue. Worked very well.

CLR ... Calcium, Lime and Rust Remover does a great job.

Great stuff, does what it says it does. I use this to clean automotive heater cores with a recirculation pump while they are in the car. Why? because CLR unclogs them, increases heat output by 30%-60%, and that’s a lot easier than removing the whole dash to replace the core. No product is perfect, but this one is very good.

It didn’t get the rust off
