CLR PRO Commercial Drain Maintainer and Grease Trap Treatment, Preventative Maintenance Bio Enzyme Formula, Reduces Odor and Breaks Down Grease, 1 Gallon Bottle

This is a very good product for keeping drain pipes in your bathroom and kitchen clear. I use no more than 8 ounces in each drain monthly and achieve very good results. This product is cost competitive with other more expensive brands that have aggressive and appealing marketing. One gallon lasts me for 2 1/2 to 3 months for my house that is three bedrooms and 2 bathrooms.

The product works good and we don't have to clean grease traps as often, however, beware of price. I ordered this in June 2016 and it was $51 and now is $85. Its not worth $85 when you can get it cheaper elsewhere. Watch the prices of what you are purchasing!

Haven't used yet, but it is what our maintenence staff use to unclog our in sink disposal

This CLR maintainer works great on grime, causes drain to flow better. Super at controlling odor. It saved me plumbing cost. I recommend this product.

Didn't work on hair or what I purchased it for the odor coming from the drains in the bathroom and kitchen.

This product breaks up the grease, and been 2 years, no sump pump clogs or over flows.

Just what I wanted

Used this as an additive to a grease trap. Seemed to work very well, but a little pricey.
