The only way I know is to remove the glass... we've been putting it off for a couple of years now - sigh

This is a job I have been intending to tackle for the last three years, Sbg! I hope that someone comes up with an alternative to removing the glass in the roof - somehow I just don't fancy it.

yes me too. Dont know how to take the roof off safely :o(

I read that a plastic seed label slid along between the glass and frame would work - I haven't tested it out, though!

Worth a try Barbara

So who's going to try it out first?? lol.

Somebody with very loooong arms. I ain't climbing up on the greenhouse roof!

Maybe we could train naughty daughter cat?

SBG, It takes time but with steps inside you can remove most of it with a thin plant label. Vinegar in water will help move the hard bits that are between the glass. No need to take the glass out. Outside big pieces can be brushed off, but it needs to be sunny. A swimmimg pool brush is ideal for outside. Brush downwards from the top.

Sorry Barbara I hadn't read your piece, but it does work I have used it many times.

There are times when I hate my smug hubby.....
he has managed to get most of the stuff off using the hoe on the still frozen outside lumps of moss..... only 2 clips have sprung out.
He now claims a thin hacksaw blade on the inside is within my capabilities ....... cheeky devil.
I hope it will work if not i will try the label between the glass.

thanks for all the suggestions.

I might give it a try in the next few days. fingers crossed.

Our moss is all on the outside and as himself says we are NOT clambering over the GH roof... so ideas???

well as said above hubby scraped at it with the hoe. all frozen stiff and came out really easily. just be careful up a ladder next to the glass.

Hum... nope do not want the glass all smashed.

Use a light long handled brush, Carol. As said a swimming pool brush, but not when it is frozen.

I think I'll let Mr MB try that... then if it does not work he can blame me!

hubby uses the power washer on a low setting to clean the glass. I dont even like doing that. scared i put a pane out. now that would be a pain :o)

I am so lucky to have a greenhouse with glasses in one long piece. It was more expensive but absolutely worth the money. The glass is 4 mm instead of the standard 3 mm.

Just a small advise for upcomming greenhouse-owners.

thats interesting Hanne. How long is your biggest pane? my greenhouse is 20ft by 8ft. It was originally two10ft x 8ft and my big pain [hubby 6ft] {joking I love him really} joined the two together for me. So I have doors at both ends.

Don't worry Carol, we have to blame our wives for everything, it's traditional LOL.

I put in a picture in a blog.

Every New Year I clean between the glass with a plastic plant label. Its a slow job but with the heater and radio on and a glass or two of something festive I can stay in there for ages.It does a good job. Alternatively use a pressure washer later in the year, that can also be effective but watch the pressure, the glass could easily break if not used wisely

darent have a festive drink incase I get 'overcome'. I am very cautious in the greenhouse. seen too many casualty tyoe incidents. ughhhhhhh.
