Default Cleaning salt water stains off windshield

The 1995 boat I just bought has some very hard-to-clean spots on the glass windshield that cloud my vision from the helm. I can Windex it all I want, but those spots are not going away.

Is there a simple, cheap solution out there to clear up this problem? It would be nice to be able to see through the windshield and not have to stand on my tippy-toes to see over it.

baking soda works great for removing bugs from front of car and windshield. probably would work for this too. slightly abrasive, but i've never noticed any scratches on my windshield and i use almost evertime i wash the truck or car during summer. i just use a wet cloth with a small amout on the cloth.

check out the line of products from meguiars at west marine or at their website. They make some awesome stuff I started using about 10 days ago that is basically a rain x type of thing for acrylic. Not only does it remove them, but it prevents their return and makes the windshield shine up nice...

Stay away from Bar Keepers friend because it will make very tiny scratches. Use a cleaner designed for plastics such as the Meguiars mentioned above or the equivalent Starbrite products (get the "cleaner" not the polish). Wipe it on with a soft cloth and the stains will be gone in a flash. Rain-X does a great job, though it doesn't last too long. Be sure that the glass is totally clean before applying the Rain-X or you will seal in the dirt.

He said glass, so barkeepers friend should be OK. You can try vinegar as well.

To nuetralize and dissolve salt, you can use a mild acid, such as vinegar and warm water.

Rain-x makes a glass cleaning "compound" of sorts that cleans glass fairly well (water spots, etc.), you might want to try it and then follow-up with regular Rain-x and you should be good for awhile. As others have said, make sure glass is good and clean prior to using regular Rain-X.

I have successfully used Bon Ami cleanser, and they say right on the can: will never scratch anything!

Bad_Andy,

I wouldn't use Barkeepers Friend on plexiglass or glass. It contains oxalyic acid and etches surfaces it is placed on. A lot of painters use oxalyic acid to etch and prepare surfaces prior to exterior painting.
Go to a super Wal-Mart and go to the RV section. They have a 8 oz. (or so) spray bottle that serves as a cleaner, polish for plexiglass, and gel coat that works very well on plexiglass windshields. It cleans the bugs off of mine and does not damage the glass at all. It's really more of a polish.

Just had the same problem. I used rubbing compound with steel wool. Came up real nice.

I don't think that acid reacts with glass.

Any kind of wax and some elbow grease of a polisher/buffer.

The only acid I know that can etch glass is hydroflouric acid. Oxalic acid is pretty low on the acidity.
