CLR Brands Clog Preventer Monthly Build Up Remover, 42 oz. Bottle, Drain Cleaner

I was so glad to find this CLR Clog Preventer. I've been concerned about the drain pipes from the kitchen sink. As hard as you try to stop it, there is always stuff going down the drain. Keeping the pipes treated will really help solve slow draining as well. Glad I found it on Walmart.com when doing my grocery shopping.

Good product, fast delivery

Wanted a product that would be easy on our 50 year old cast iron sewer main. Safe to say this stuff works, and results are impressive! Left it in the kitchen, shower, and bathroom sink drains overnight and the next morning, the drain flow was noticeably faster! Very impressed and not a waste to do once or twice a month.

a little pricy. but does the job !

Just started using this product but so far so good. I was able to clear a drain clog in the sink! I have used another product for several years (much more expensive) and doing this does work.

Slow bathtub drain cleared up overnight with this stuff! We're now going to use it regularly in all our drains to prevent the build-up. Walmart has a very good price on this, too. So happy I found this product.

I thought that it would not work 🙄The first time trying it. 😶 But turn out that it did! 😅 I really glad that it did work! More faster that I thought 🤔 using only 2 oz as it says in instructions. Know the water is not stuck anymore on the sink and shower! Thanks!! 😊 Just is case wait for 5 minutes o more. before draining out with water again. 🤔 I really would buy it again. Is ready good. And I used only 2oz on every sink and bathroom shower and that is great instead of using all the container Of other products that could not get the Job done.

This worked perfectly for my slow drain in bath sink works as described to remove tooth paste and soap scum. After putting it in drain and let it sit to work then closed stopper added water and opened and closed stopper rapidly and the black scum fell off. Now use once a month. If used by directions it works will continue to buy this product as now my sink drains like new.

I had a slow sink, after washing hands the basin was half full of water. I've tried many products with not a lot of success but I tried this one. It took maybe a few days longer than I was hoping but it truly worked! I will definitely keep this on hand.

Unfortunately it didn't work.
