Window Cleaning - Water Spots and Fog Film?

jswiss said:

After a week or so I get a foggy film on the inside of my window can I prevent this?

Since we are talking about windows...how can I remove water spots with out scratching the window?

RainX makes in interior fog resistance application, you can try that.

As for the outside water spots, try a clay bar.

outside windows - you can also try vinegar soaked on a rag and let it sit for a bit. if its really bad (like it gets in my water up here) then glass polish and an orbital works quick. i've never had luck claying a window

Outside Water Spot Removal:
Water and sponge with either "Bartenders Friend" or "Bon-Ami".
These wont scratch the glass like comet and it will completly clean the surface of tar, bug gut leftovers and water marks.
Then treat with Rain-x to get the glass to Bead water again.
Inside Ive been using invisible glass per the suggestion af a few users here.

i use Bon Ami on the inside - found it does nothing to the watermarks outside.

Thats what they mean by "Hard Water"!

invisible glass works for me. And when I am washing my car I try to keep the whole car wet till I am completely done then use a squeege to get all water off the windows and car then follow that up with a micro fibre towel for the left overs...

the foggy film inside may be environmental stuff. do you smoke or do a lot of stuff outdoors. the rain-x anti-fog seems to help for moisture fogging.

as far as exterior, i use Dirtex. it's a spray cleaner that cuts through touch stuff pretty quickly and i've never had a problem with water spots.

+1 for Invisible Glass

It works very well

+2, Tried Invisible Glass yesterday after I washed the truck, it worked very well, I cleaned both inside/outside with Invisible Glass cleaner after I washed the entire truck, I did not see that foggy film on my front windshield this morning. Thanks to those who suggested to use the Invisible Glass product for the foggy film issue on this thread. As I've tried many different products with no lucks, thanks again for this helpful thread.

Isn't fogging on the inside of the glass cause by the plastic "gassing" from the interior? Especially bad on hot days when the interior heats up.

fine steel wool gets the job done on water spots

ready for this? try newspaper balled up in your hand and dab a bit of water. i promise it works and VERY well. no streaking what so ever!

On both the inside and outside, use a solution of a quart of water and a few drops of Dawn. NO SUDS!! Take a window wash tool, soak it, wring it out and wash window. Use a squeegie to get the solution of the window. It will last on the inside about 3 months without anything else. On the outside, treat with Rain-X every couple of weeks. I do not like the Rain-X for inside use. It tends to leave an unclear film on the window. I use this method for all windwos on the house and truck. It works great.

Only 2 things I will ever use on windows. White vinegar or 0000 steel wool. The steel wool is amazing on glass and chrome, but creates a bit of a mess when it starts deteriorating. I thought my chrome on my 68 Mustang was clean until I tried the steel wool. It is a great detailer's secret .

I worked in pro detail shop 30 years ago - only thing we used on windows was 0000 steel wool dipped in water, towel dry - no residue and dirt cheap. Try outside air setting on HVAC, not recirculate. Recirculate allows humidity to build up inside - or, leaking heater core if fog is slimy like antifreeze.

I never thought about dipping the steel wool in water. Does that keep it together well?

I've had luck with Armor All Glass Wipes....no scratching, no linty residue from a towel.

+3. I worked in a detail shop when i was in high school. We used 000 steel wool and Sprayway - the foam kind. 2 lint free rags that were washed in mild soap with no dryer sheet or fabric softener. Spray, steel wool, wipe with 1 rag, wipe till dry with the other. Perfect inside and out everytime. Dont clean your windows in direct sunlight either.
