tips to remove saltwater stains on glass

soak it for a while? i dunno if the vinigar didnt work then your screwer

For mine we just used A spray bottle of vinegar and while wet razored it off... Sorry man..

Last resort CLR.

I think I would just use CLR and wash it really well after.

You can use a car wax cutting polish which works by removing a thin surface layer (in your case, glass). I am sure your local car auto specialist will be able to recommend a strong one.

Whoa, some of this sounds serious! Me? If the vinegar doesn't work (first option) I would use a paint scraper w/ lots of new, clean blades (blades are oiled to prevent rust) and a bottle of water with a drop of biodegradable soap (to reduce surface tention (try camping soap)). Scrape it with an up and to the side motion with the blade at about 30 degrees or less. No scratches and the calcium should come right off.

If that doesn't work, try the blade dry, but in an area that can't be seen. Be sure that it isn't scratching the glass before moving elsewhere. Remember, wet deposits are harder to get off then wet ones so the idea is not to soak the deposit, just use the water as a blade lubricant (spray, immediate scrape). This is oposite to the vinegar idea, which is to soak and disolve.
