i run into this issue today , the car is an classic , so the glass composition may be a bit different...? softer easy to itch?
what it seem on the windshield was tree sap super bonded , small dots around 50-100 dots , it catch the towel when i wipe it , i use a blade to level it out and remove the excess , but was still left small dots behind , same place.
looks like is stained?
the towel goes smooth on it but are there ,very visible , like stain spots from a sprayer if i can compered with something.
i try terminator , rubbed on it and let it sit , and not a scratch , that thing is the same...

any ideas? i forgot to try claybar.... i doubt it if will do anything
are any chemicals that can soften the sap without damage the glass?
 
I used in past (with variable success) a paint thinner / lacquer thinner to remove tree sap from the clear coat/paint.
But I don't recommend you do that, you may easily do more damage than good if you are not careful.
 
Use some: "passion behind the towel"...on the tar with:

-A Zippo/Coleman lighter-fluid (Naphtha)-wetted terry towel.
-Barkeeper's Friend on a dampened terry towel
-Meguiar's #4 on terry towel.

i use a metal blade to level it out , that usually removes it, but didn`t remove all of it , and i use treminator with a paper towel and some passion.
but what was left behind look like stained/itch in the glass from that sap, even if wasn`t itch it looks ugly , i can`t leave it like that.
that`s why i need some ideas , next time i see the car to have 3-4 options ready to try.
thank`s guys and keep them coming :xyxthumbs:

i will update what worked , if .....
 
Just try compound(like 105) and an older cutting pad or MF pad. Also, Detailer's Pro Series(AG in-house brand) High Performance Glass Polish works really well at this. Actually just dealt with this on a car that had been parked under pine trees for about a year. Used the Sraprite blade on the paint and glass and also on the glass after a few passes with glass polish.
 
Try a bit if compound. If that doesn't work, then go straight to glass polish and pads. What year is the car? Does it have the original windshield?
 
although i have never tried it on an expensive/rare/classic car, i use 0000 steel wool and AIO polish for all kinds of contaminants on glass. From my year of experience using steel wool on glass with AIO polish as a lubricant, I have not damaged any glass. I actually got the tip from a glass shop guy who did some detailing as well.

Sometimes i use 000, with great success, but then again, i do work for a car lot lol. For my application, it works excellent! And is quicker than a rotary and wool at completely removing stuff like water-spots
 
I believe CarPro has pads specifically for glass. I have never used them, just trying to help out. You could even call them and ask as them questions.
 
Steelwool ---> :props:

Compound? Polish? :confused: Idk... Tree sap is like a honeyed glue, I would be very surprised if compounds and polishes and pads would remove it ... but then, I never had to remove tree sap from the glass... so I just don't know...

Interesting to know how Pros do it.
 
I only use compound or DP's HP glass restorer after getting the bulk of the sap off with a razor blade. If the sap is dry the razor works fine; the sap just pops off. If the sap is tacky then a tar/adhesive remover with paper towel works well. Then polish the glass to remove light etching and any remnants, and deep clean the glass. I haven't used steel wool because I don't lime the risk. I may try it the next time I have the chance on a vehicle that is not gonna be scrutinized for any imperfections in the glass. For a vintage car I wouldn't attempt anything more than a metal razor blade to remove the bulk of the sap and then follow with Ceriglass on a CarPro rayon disk. FG400 and a cutting pad does a great job a removing water spots and imbedded contaminants and is safe than steel wool IMO.
