...It's only visible from the inside of the car. How d'you get it off?

It's impervious to high pressure water hose, I've tried that several times.

The green colour is visible if you sit in the driver's seat and look at the exterior bottom of the window. It's a bit less than a centimetre high but runs the whole length of the window under the exterior rubber trim on the door at the bottom of the window. Something needs to be inserted between the rubber trim and the glass to clean the window...but what? Plastic knife with some kind of cleaning agent attached - too wide to fit.

The trim won't detach without a trip to the dealer.

Any ideas?

Probably best to post a photo, it'll make it easier to see the problem and work out the solution...

What car is it. The trims usually just push on, but can bend VERY easily when taking them off.

Wind the window right down and push a damp cloth in the gap?

I will as soon as thumbsnap decides to cooperate.

The gap between the window glass and exterior trim at the bottom of the window is far too tight.

W211 E Class M-B. I wouldn't like to try to take the trim off...it looks like I'd have to take a lot more off as well to gain access... .

I don't think this will work because to get at the grime the window will have to be raised, which will push the cloth up. If I've understood correctly?

Thank you all for your help, as soon as thumbsnap is mended I'll post some pics which will illustrate the problem a bit more clearly.smile

Ah - it's on the glass? It's usually on the rubber.

Yeah it's odd. And nigh on impossible to get at.

So the interior door trim sits a little lower than the outside wiper strip for the drop glass, this means you can see the external side of the glass lower strip from inside the car? If I've understood that correctly, you "should" be able to lift off the outside wiper strip and use a scraper to clean the bottom of the glass. I'm sure on those the seal is a rigid rubber type that lifts up and has a plastic clip at the doorframe end (not the mirror end), its only pushed into a "V" shaped channel in the door. Lift it out very carefully as they're easy to kink and then its almost impossible to refit it.

Yes.

This is it: There appears to be no obvious way of lifting it, hence trying to get something between the outside wiper and the bottom of the window.

In an ideal world I would attempt this. However, knowing my luck...
So far this is the best solution, many thanks. I will try to find diagrams of the doorframe and how the trim comes away on the internet before attempting this myself!

Once again thanks to all for your answers.

N.B. thumbsnap still not working but I will post a pic when I can.

If easier, take off the door panel, wind the window down a bit and then get at it with a cloth that way?

It's on the other side of the window so that wouldn't help I'm afraid. Thanks anyway.

The outer scraper lifts off quite easily. Start at the back and do it slowly it will come off a treat.

The trick is to open the door and stand on the inside of the door with the window down, finger tips under the trim/scraper with your palms on the top of the glass and squeeze your fingers to your palms, that way you can't "overshoot" and kink the trim (if that makes sense)

Right I'll give this a go, thanks.

Could possibly trickle some anti-algae liquid down there, available from DIY places. Wet&Forget is one brand. It dissolves it away to nothing.

I'd be a bit careful with the algae destroyers - some of them are just very strong bleach solutions, not sure I'd want something as corrosive as that inside my door skins.
