50 Customer Reviews on “Does CLR Really Work?

  1. I bought CLR to clean stubborn grey strains off the toilet bowl and clean the shower’s stubborn calcium deposits. Nothing. It didn’t work at all. It was expensive too – $15 for basically water. Tried it on other recommended items – nothing.

  2. Bit the bullet and tried this product, tv ads looked to be the product I required turned out to be a waste of money and effort. Rubbish product and product should be removed from shelves. False advertising at the best.

  3. Aces! I highly recommend Original CLR for cleaning your shower / bath. I used CLR for the first time to clean a neglected stand up shower at an elderly relatives home as the hard water, soap and even some mold were at a level requiring an hour or more of hard scrubbing had I used my old faithful powdered cleanser. I am very glad I chose CLR. I poured it directly onto a yellow/green scrubby and it easily removed much with a pressured wiping, and removed the tough deposits with a regular strength scrubbing. Very easy & effective compared to what I used to use, I finished the job in about 1/2 the time a regular weekly or bi-weekly shower scrub would have taken. I now use this to clean our home bathrooms exclusively. Be sure and wear appropriate gloves, I use the thin inexpensive nitrile type.

  4. I moved into a house that is on a well. The rust ring started building up right away in my toilets. I bought a jug of CLR after seeing the convincing results on the TV commercials. After an application per the instructions, the rust ring was still there. I tried more CLR and a scrub brush. Some of the rust came off but not enough to make it not visible as the commercials seemed to make it. After quite a few applications and letting it soak in for some time, the rust rings persist. I read the instructions again thinking maybe I didn’t buy the right formula, but the print on the jug says it will remove rust rings. Maybe my rust rings aren’t the kind of rust they are implying.
    I sprayed a little CLR on a dust cloth and it seems to remove dust off my furniture with no problem. Perhaps that’s what their commercials are implying.

  5. I tried it and it acted like I was just using water. This is one of those scam products that doesn’t work but they still make money because of the churning population. We are each victims at $8 or $10 so we go on with our lives, but a law firm could file a class action lawsuit and put a stop to this nonsense from Jelmar

  6. Save your money. No this product does not work. I am attempting to remove iron stains from a brand new toilet that are showing up after a few months. The stains are not even that bad. CLR not working at all.

  7. If you are thinking of buying CLR, let me offer a suggestion. Put 50 cc’s of dishwasher detergent in a one litre container, add 50 cc’s of household ammonia, add 900 cc’s of water. You will have a far better cleaner at 1/10th the price.

  8. I had a bad odor coming from my dish washer, tried numerous special cleaners for dish washers, to no
    avail. I even thought of replacing my hot water heater due to this smell on my dishes and pans!
    I spent a small fortune on these cleaners, waist of money. As a last resort, I tried clr in my dishwasher cups, ran it through the regular cycle, and to my amaze odor gone completely!!! It’s been 3 mo.s since the treatment and still no smell!!!
