Jelmar CL-4 CLR 128-oz. Calcium, Lime & Rust Remover

Removes lime scale perfectly

Good product, Good speed of service.

This product can be used in water pipe???

Rarely rarely and hardly never write a review. I've lived in my home, everything pristine and new into an area with incredibly hard water. Tried various chemicals over the last 25 years and nothing seemed adequate in even touching the rust stains in the shower. Yes I do have a water softener and shortly use the rust out salt in it. This stuff diluted 50/50 with water worked so good. I sprayed it on, waited not even a minute and used a body scrubbing rag just lightly rubbing it in and then rinsed off. I've included some pictures to show the after and so sorry I didn't take any of the before. But you couldn't see thru the glass at all and the walls were so rusty stepped out was so embarrassing for anyone to see. So judge for yourself and write with any questions and I'll try to respond to anyone. Thank you CLR for an amazing product.

Perfekt reinigt Kalk und andere Ablagerungen schnell und dauerhaft

Works great. My toilet had hard water stains calcium lime and rust. Made it look new again. My sink too. Great product 5 stars. Great seller fast shipping

Le pire produit, je ne comprend pas dutout les commentaires positifs, ce produit m'a coûté 88 euros, so efficacité est moins que celle du vinaigre, si vous avez du calcaire passez votre chemin, c est une pure arnaque

Years of toilet trouble: slow drain or no flush. Got to point only fluid would go down. Tried everything and a plumber said calcium and lime; brown stain that looked like toilet wasn't glazed. Plumber said leave it in over night but we didn't want to do that and did it for two hours 2x. Amazing !!! This stuff saved us hundreds of dollars.
