Optimum MDR Mineral Deposit Remover - Removes Stubborn Mineral Deposits, Heavy Duty Water Spot Remover for Cars, Trucks, SUVs, Boats, Motorcycles, and RVs (1 Gallon)

Gods quality for detailing

I bought this because I left out of town and forgot to shut off my sprinkles so my car got covered by a bunch hard water and deep water etching. This did not remove the deposits at all and had to resort to wet sanding with high grit sand paper, buff, and a light polish. Keep in mind my car was ceramic coated with multiple coats so this might have made it difficult in removing the mineral deposits or why this product didn’t work. I’ll apply this to my daily driver car and update you all of it works on non-ceramic treated cars. So far I don’t really recommend this product and without a buffing marching you’ll be using a ton of elbow grease for results not up to par like traditional paint correction.This stuff also didn’t work on my windshield.

the the product does not work, it does absolutely nothing!!!, such a bad waste of money and time does not work, it does absolutely nothing

It would not remove ANYTHING from my paint! Not even water stains that weren't even mineral deposits! It's nothing more than thick and useless gel!

Tried to get hardwater stains off my Mustangs PPF and Feinlab heal lite but did not work. Wish there was something that would work without having to buff them out and ruin the very expensive ceramic coating.

Terrible product. Followed directions exactly and even used their ONR as recommended... this product didn’t even make a slight difference. Sent both back for a refund and went with a different product.

Does not work at all. Zephyrs water spot remover is more effective

works well
