Purchase my first used greenhouse from 1970s bought from my friend. It is in a good condition but the glass I am very afraid to break it when to cleaning the moulds and green algae is on the glass it is not easy to remove as what I thought. Is there any removal chemical on Amazon make easy to remove without crack or breaking?
Thanks

    I find the kitchen sponges and the washing up liquid work well

    I agree with nut - also the side of an old credit card works really well for the stubborn bits

    Cleaning on a rainy day helps or when you’ve had rain, algae is softer then.  I use pressure washer.

    We had a bit of mould in the bathroom and the supermarket brands of mould remover were pretty useless. However HG Mould remover worked fantastically. You might want to try in the greenhouse if you’re determined to remove all traces of mould.

    I use Armillatox to clean algae, banned for on the garden use but for cleaning glasshouse,s and paths patios etc I find very good.

    Cheap supermarket bleach washed on and left overnight will kill the mould- then hose off. :)

    All good recommendations from fellow gardeners above but can I suggest an Old Toothbrush for in between the panes of glass works a treat to get out all the yucky green algae along with just Water/washing up liquid solution, works a treat flyingpostman.

    I bought a sponge from the car parts place that is basically a huge version of a kitchen sponge with a nice rough side to it. Makes short work of any green stuff on glass so I hate to think what it would do to car paintwork. The best part is that it's got a deep slot cut into the soft side so you can wrap it around a rake or brush head and use it to clean the roof glass from the ground.

    Given the choice though I'd use the pressure washer as the lazy (and much messier) option.
