Really works

I've had water spots on my car windows for ages and nothing I tried would remove them. This took them right off and with relatively little work. I wore gloves and was careful not to get anywhere but the windows. Very happy with this product and I recommend it.

Scanned online for one of the best for getting those spots of auto glass and it was consistently rated as a top product. And it does what it says. The thickness helps with the cleaning a lot, since you are usually working on glass that is upright on a car.

Worked very well on our glass shower door to remove mineral water spot stains. The stains were very built up so it did take a few rounds to “eat through” all of the layers. I would recommend layering old towels underneath the shower door to prevent the orange from getting on your floor.
