I have these spots that are not removed by simple wipe of damp towel. I use rain-x stuff on the windshield, so I tried them too but it didn't remove them. When I use my finger nail, they seem to get off, but I have not tried on all of them. Any idea what they are and how I got them? It's not from hard water.

 

could be paint overspray by nearby construction workers. who knows. clay bar time. see if that works.

 

Ha! Claybar is solution to all my problem in this forum.

 

While we are at it........any tips on cleaning the insides of windows?
After 6 months, I am getting that foggy build up.
I use Glass Plus.....spray it on a cotton rag.
But I need to go over it several time to eliminate streaks and fog.

 

I picked up some kind of windshield/glass cleaning microfiber cloth. To my surprise works really well.

Normally works good enough just the dry cloth. Or, I use one cloth damp with water, than finish with dry cloth. No solvents or cleaning solutions have been needed.

 

Yep just use a microfiber. Nothing needed on it. Can spritz on some glass cleaner I suppose. But for tinted windows I wouldn't since you may dull the film.

Don't forget to remove the brake light and clean the glass behind it!

 

I remember a recent thread on the brake light removal, with pics.
But, can you review here. It just pops out?

 

How do you guys wash microfiber towels? I threw them in washer and then dryer. I feel like there are small particles that left on the windows when I wipe over it dry.

 

Yeah I usually wash them in the washer and dryer, but sometimes they get little pieces of lint stuck to them, even when I use a dryer sheet. If that's what you are experiencing, just make sure and wipe off the small particles when the car is totally dry.

 

 

Yup Chemical Guys have great instructions on the microfiber towels. When you wash them you're supposed to wash them with other microfiber towels and only use detergent and nothing else. They say never dry them in the dryer. If you put them in the dryer you're supposed to just use the "air fluff" (no heat) option or hang them somewhere to dry (this prevents the fibers from burning up). I follow this and my microfiber towels have stayed brand new pretty much.

 

 

Lol that article is the one I had read A LONG time ago clearly I didn't remember what I had read. Thanks for sharing!

 

 

yes, use a microfibre towel, squeegee and soapy water. for cleaning the outside of the windows have a look at the wfp poles that all the window cleaners use. I got one for my house, but also use it to do the car as well. just don't use a lot of pressure with the brush on the car paint as the bristles are quite stiff. I haven't had any scratches yet though. good tool to have.
