I picked up a car from Florida and is it ever loaded with brown spots on the windows! It must be from the very hard water there. Any tried and true ideas on how to remove them?

try I think it was called bon ami, my dad used to use it on his glass all the time. Of course that is if it's not the glue in between the layers discolored or delaminating.

Might try white distilled vinegar to see if it cuts it.

Be very careful using anything that has an abrasive, or can scratch the glass. I am assuming it is side glass, which is tempered. Usually it takes a special abrasive that is used with a high speed bonnet to remove the spots. I would check with a local auto glass show to see if they can do it for you. If you break the glass, it will cost you a lot more.
Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

I've tried the vinegar trick and it usually works well except it can take a lot of rubbing. The vinegar takes some time to dissolve the residues.
Eastwood sells a glass polishing kit which uses cerium oxide (the brown powder) mixed with water. It works wonders and will even take out small scratches. I've used cerium oxide to polish scratches out of glass windows on photomultiplier tubes that were sent into outer space so I am familiar with the results.
Do a little research and you might be able to buy it in bulk rather than stepping up to Eastwood's kit.

There's this stuff called CLR that disolves Calcium, Lime and Rust. You can buy it at home depot

It does a fantastic job of disolving hard water marks.

I would not use CLR on any part of the car. It eats aluminum, and is not to be used on any painted surface (from CLR's website)

. I used to work in a mirror manufacturing factory , all the glass was rubbed down with cerium oxide before silvering , also was used for polishing out scratchs , glass edges and bevels , we had buckets of it , but that was 30 years ago
