Directions

To Clean Tubs, Toilet Bowls, Sinks, Porcelain, Cement, Stucco and Brick: Mix equal amounts of CLR and warm water. Apply directly to calcium, lime or rust with brush, cloth or sponge.

Run one additional full cycle (wash and rinse) with water only to rinse machine fully. Shower heads: Mix equal amounts of CLR and hot water. Submerge shower head and soak for 2 minutes. Rinse thoroughly with cold clean water. Repeat process if necessary. Wear household rubber gloves. Always stand on a non-slip surface for all cleaning jobs. Do not use CLR on natural stone, marble, terrazzo, colored grout, painted or metallic glazed surfaces, plastic laminates, Formica, aluminum, copper, brass, steam irons, refinished tubs or any damaged or cracked surface. May etch older sinks, tubs and tiles. CLR may return older cement to its original white appearance. Avoid contact with wood, clothing, wallpaper and carpeting.

Bought for the shower, found a miracle for my dishwasher

Bought for the shower, found a miracle for my dishwasher
I’ve used this for awhile for my sinks and toilets and works well.I was looking up where to buy this the cheapest, and found a review that talked about using it for the dishwasher. Now, I live in an old apartment so I have no control over the pipes and old dishwasher. All the dishes have a lovely hard water film over them. I bought the Lemi-Shine dishwasher boost, the dishwasher cleaners, and different detergents all with minimal results. I thought it was hopeless, and chalked it up to hard water and old pipes. Decided to give this a go. After the first cycle, looked like there was still residue so ran again. When I went in, there was a powder on the heating coil so took a towel and wholly cow so much orange residue came off. Wiped down the whole inside with CLR to make sure that like the spraying holes and all were cleaned. Then ran a empty cycle to rinse it out.I was shocked after the first set of dishes came out. I didn’t tell my boyfriend, so he said brought one of the glasses to me when he was unloading because he was shocked and confused. It worked sooooo well!! You can see in the picture on the left is one that hadn’t been run yet, and the right is after running. This is with no extra additives or special detergents either. I thought there was no hope, but this stuff is amazing!!!!!

Reviewed in the United States on March 11, 2022
I used this on a dirty sink at my dads house. He swore nothing would come off. Not only did it get the gunk off but it took care of the deep staining. I’m gonna try again in a few days to see if I can get more off. All I did was let some soak and then scrub it with a scrub brush. It also said that it could have a high chemical smell. But I had the fan on in the bathroom and the smell was not bad at all
