Your greenhouse should be thoroughly washed inside and out at least twice a year - Spring & Autumn - to kill off any lingering bugs and to maximise light transmission. Cleaning Systems will make easy work of a hard job, making even the most inaccessible places easy to reach. Also useful attachments for  general cleaning of windows, doors and even car cleaning.  Here we also have garden refuse sacks, dustbin liners, wheelie bin liners, rubble sacks and heavy duty garden refuse sacks.
