last job today was gutter wash Inc conservatory roof. To do this i suck tap water out of 200 litre barrels. The green on the roof spars was well stubborn so I put me suck up pipe in the demin barrel & gave it a blast. A tad better: then I thought while this is set up, I'll blast the windows. Never cleaned this house before so shall be interesting to see how they turn out (took 8 mins for house & con! Mind you I didn't bother scrubbing )
It's just a shame the hose is so damn heavy, or could be on a winner here. Maybe useful for schools withvdecent windows?
