Fine scratches on door glass

Hello.

Is there any product you guys recommend to help mask scratches on door glass.
It’s been caused by dirt/grit on the rubber and the window sliding up/down against it.
I want to try and make it look better if at all possible even if it leaves fine lines.

Perhaps some sort of filler product might work?

Advise and suggestions would be appreciated.

Thanks
 
Sorry to jump on this thread but I'd be also interested in this, having researched, this seems to be a common issue and polishing them out is either not possible or very difficult/time consuming depending on who you ask.

I've considered replacing the glass itself but worried it would just happen again or its a big job to DIY (anyone have any ideas?)

Thanks
 
Cerium Oxide is the only product that works on glass, which is like a paste you put on and then polish.

Note that the cause of the scratches is the rubber where the glass is pushed up and down, so you would have to really clean that to avoid it happening in a very short period again.
 
Agree, I think if you were going to the effort of replacing the glass you'd also replace the those rubber weather strips too (assuming they are not NLA).

I noticed those rubber strips are almost brittle like around the rear edge of the door window. Although that is not the area where the fine scratches are on the glass. I am going to try and clean any gunk off the rubber strips and see what I can do to mask the fine scratches on the glass.

You also need to use a machine polisher for the cerium oxide.

If the scratches are at the bottom of the glass at the trim then the window will probably need taken out to polish correctly.
 
Replace the glass and never drive/ take it outside again.
As putting outside will always attract dirt and as one surface moves over another the dirt particles will scratch it.
 
I’ve had multiple older cars with this issue. No easy cure as far as I’ve found. Windscreens replaced, door glass replaced in all my instances.
 
You can't remove glass scratches without deforming the glass but you can improve the appearance.

First, drop the window and use anti-bacterial wipes (like multi-surface kitchen wipes) to clean the lower window seals - force the 2 rubber strips apart and repeatedly drag the wipes along the inside edges to remove the built up green muck and grit. Keep doing this until the wipes don't pick up anything.

Then treat the rubber seals with a silicone lubricant to stop them drying out - don't use loads otherwise it will smear on the glass.

Clean the glass well - normal glass cleaner first inside and out. Then use a glass polish that has some mild abrasives - I use Autoglym Glass polish first, failing that I go to Glaco Glass compound. You can use Cerium Oxide (jewellers polish) and a polisher machine but it will take a layer of the glass off which then changes the path of light through it causing visual changes. Not too much of an issue for side window glass but I wouldn't do it on a windscreen. This can also cause a low spot in the glass that the wipers now wouldn't contact as well. You can also risk cracking the glass due to heat build up.

The main reason you notice glass scratches is because a fine layer of dirt sits in it that doesn't get removed when the glass goes up/down or with a light car wash. The key is to do the above process and then use a polish that has some fillers - like Autoglym Super resin polish - or a clear wax - and then use a hydrophibic product - like Glaco DX - which means water runs straight off so the window is less likely to get dirty in the first place.
