window water spots impossible to remove

I'm trying to remove very hard water spots on some old windows. I've used Ammonia, vinegar and a steel wool pad on a 1-inch section to see if that at least works. So do I need some like Acid eating product or something?!!?!?!?

Once you have the window clean, put a coat of automotive wax on it and the stain won't come back as easily.

You may want to stay away from the steel wool even fine on windows it may scratch. You may want to try a CLR product diluted at the reccomended levels on the bottle. Try a microfiber towel when using it make sure you wear chemical resistant gloves when trying. I wouldnt leave the product on long and make sure there is nothing it is going to splash on or drip on that it may damage.

I did some checking most CLR products can be used on glasses/windows so just read the back of the label to make sure.

You can find these products at your local home improvement store or online.

Acid rain tends to etch windows. This damage is permanent.

The windows have overhead and I don't think acid rain can get to it the rain would have to be coming almost sideways. My friend who owns the house tells me it's from the sprinkler system and I think he said it's chloride or something, but I thought the sprinkler system used plain water. I'm going to try the Zaino glass cleaner + polish (Z12 if I can remember) thier wax (actually chemical polymers are the best in the world) they say they havn't found a stain that Z12 couldn't tackle.

Anyways I will try the CLR which he has at his house. This will be my last atempt and maybe I will try Aceton while I'm at it
