Got bad hardwater spots on exterior glass? tried n true

[Questioner]

finally got around to google and waterspots ...i had a REAL bad waterspot issue...the previous owner i sure would like to question. idk wtf happened to her but dayum hard water spot galore on all my glass. watched a yt vid on cleaners of various chemical makeups and apparently the magical oxalic acid and 0000 wool does the trick. so i venture on down to wal mart and find "bar keepers friend" cleaner in a squirt bottle, some good ol nitrile black disposable gloves and some 0000 steel wool. total $8.58. got home and squirted the windshield up and got ta scrubbin like mad man. and low and behold !!!!! CLEAR GLASS .....well, after the second round lol, but still i have a uniform windshield with no waterspots. just lettin the group know, bkf works.

Good to know. I have a water spot issue on the glass of one of our older cars so I will have to give this a try. Thanks for posting up!

Have been trying to clean my windshield with all kinds of products and cloths. Used an old can of Glass Wax that I had. Best clean windshield I EVER HAD !!

I hada major issue on my tundra years back. Like the previous owner worked ata chemical plant (possible around here).

Ended up picking up a telescope lens polisher which worked amazing

I didn't know Bar Keepers Friend came in a bottle. I learn something new everyday
