I recently bought a large 2nd hand greenhouse ...and after good advice here
got all the glass home without a single breakage.
Green house has now been erected ..... but before I refit all the glass, (
100 panes) thinking about best way to clean it.
As it's been in a greenhouse for a few years it's green, cruddy and probably
brittle.
It did get a wash down as each pane was taken out .... but certainly not
clear glass at present.

Suggestions .... ?

I have a pressure washer ... but that may be a tad risky ?

Hot water & Jeyes fluid ?

Wife, bucket & sponge ?
