    Hard Water Spots on Window Glass

    My car came to me with all of the outside windows completely covered in these water spots, so badly that it can actually be hard to see out of them at night. They give a rough texture to the glass, and I have tried everything I can think of to remove them. I have even used metal-wire cleaning pads, and yesterday I tried lime-away - to no effect. Vinegar also did nothing - I used newspaper to polish it. Does anyone else have this problem? I would love to have clear windows on this car. Thanks!

    Possibly overkill, but have you tried that glass-polishing window restorer stuff? Doesn't sound encouraging if #0000 steel wool won't touch it ....

      I just had a breakthrough with this problem! I have discovered that Glass Cooktop Cleaner does the trick! It's white goopy stuff, and when using a slightly abrasive pad to polish it, it comes right off! It take a bit of elbow grease to polish it off, but it works! I had been trying for months to get these spots off, you all should try this. Thank you 1987CP, you made me think of the glass cooktop polish stuff. Wonderful!

        Oh, interesting info. Is this stuff kind of like Easy-Off or something?

          No. It's a special cleaner made for those stoves that don't have burners on them, they just have flat glass cooktops. It's white and creamy.

            Wonder what the chemical composition of that stuff is. Got a brand so I can look up the MSDS? I know oven cleaner's active ingredient is sodium hydroxide, which is a horribly caustic nasty substance that eats anything in it's path, including skin. I hope the glass top cleaner isn't so nasty, otherwise it will eat on the trim and paint if any overspray landed there.

                As crazy as this sounds .. I actually tried using the glass cooktop cleaner to get rid of water spots on the paint, and it worked! A non-abrasive pad and a polishing motion did the trick. I then washed, dried, and applied a fresh coat of wax and the finish looks brand new. I will need to get pictures of this up soon.

                  Well, if this MSDS is accurate, its primarily made of calcium carbonate (limestone) and aluminum oxide in a water and alcohol solution. Its an abrasive cream, but it doesn't seem to have anything in it that will permanantly destroy paint. Probably does a nice job hazing it up tho. You can get similar results out of swirl remover or a polishing compound I'd bet, and those are actually designed for paint use.

                    I thought it caused a bit of hazing, but as soon as I washed and polished it with wax, it looks good as new.

                      Hard water spots is easy....Fill a bucket up with half water and some vinager and a lil bit of dish washing soap and your good to go. And as for the water spots on the paint I just recently tried meguiars Ultimate Compund...This stuff is amazing. it removed all my oxidation and water spots. And the stuff dosn't scratch paint..

                        I'd start with a clay bar and then move into the abrasives. 3m swirl mark remover would be a good start.

                          I tried water / vinegar / soap, and so many other things. I think my water spots were particularly bad. I also tried clay barring the car, and all that did was make the water spots feel smoother to the touch.

                            Maybe try looking at Eastwood's catalog, IIRC they have a glass restoring kit. I'm sure it has some sort of abrasive but whether its bad enough to warrant something like that is up to you. I try to use RainX on a regular basis and don't see any spots. Sometimes I use this glass cleaner called Eimann Fabrik Clear Vision II Glass Cleaner. If I do have any spots Windex or Ammonia doesn't get, that always does.

                              Gotcha, they probably were really bad. it took me forever to get mine off the back window. But as for your paint try out the meguiars stuff, i thought it was some awesome shit. just don't forget to wax after your done.
