Window frame effectively clean

I've experimented a bit and then I came across a "car cleaning agent", which stood around here with us. You only get it in the dealership and, as far as I know, from a company.

But I think the effect will work for other products with the same ingredient as well. And it is orange oil.

It worked perfectly, I was done in seconds. Spray on, wait 5 seconds and wipe off.

No more tennis arm after all the window plastering :)

Have just taken pictures so you can see that it works really well.

Did it also sprayed a door that was covered with adhesive tape, of course took longer, but the 13-year-old adhesive is down. Without spatula or similar
