Hard water spot help!

I have really bad water spots on this customer car I'm doing. Is there any ways to get this off? I don't have any hard water remover at the moment. Is there any home remidies to remove them? Thanks in advance.

 

CG water spot remover, clay, polishing (least to most aggressive). Unsure if anything else will work.. gl!

 

Car goes out tomorrow. Don't have time to get any water spot remover.

 

what was listed above . . . . you can also try white vinegar to help break the spots up.

 

Do you have nanoskin? It removed most on them on my neighbor's car except for the etched ones. Or else try the vinegar.

 

Ok I'll give vinegar at try. Does it work well on windows. That's the main concern.

 

If the vinegar doesn't work...on a very clean window (other than the spots) use 0000 steel wool and a fine polish like super finish or 85rd. Use light to medium pressure and inspect often to make sure you are not scratching the glass. If that doesn't cut it do you have a polisher?
