I still use dilute jeyes fluid and then power wash it for the rinse part.

Like SBG, I use dilute Jeyes fluid but make sure to use rubber gloves. I clean the glass again at the beginning of the season. Every other year, I empty my glasshouse and use a smoke candle in the springtime.

thanks both and I have Jeyes fluid ... didn't realise you could use that .....

if you have a pressure sprayer that certainly helps if not a hand sprayer is just as good as it gets into all the nooks and crannies.
