Thanks Gus
Yeah something like that , we used a product called Spiritus = (Alkohol 94% (Ethanol) ) and newspaper in not direct sunlight .... since decades from Granny to Mother to Son

.... , wish i had that yesterday eve
That is the stuff also to place into a fondue burner on new years eve or so , had always trouble to get it in Ireland cause only in Pharmacies in small doses available .... (guess one could destill it to something drinkable

. Here i get it for 2 Euro a litre
Missed a few spots cleaning the glass a lot of surfaces now in that sandwi(t)ch window now .
In one corner i have a small under 1mm gap of the new inserted double-glassing unit , but i think i should not glue ore silicon that into the timber for the time being
