What I don't understand is what your getting on the glass every four to six weeks that needs a power
washer to remove it.
Is this rural properties that are getting bombarded with snail trails insect poo and bird muck that we are talking
about or something else ?
I actually cleaned a mates 5 bed detached in under 5mins with a one and three quarter litres per minute flow, done it just to see how quick it was possible for me to go if I really wanted to. ( Didn't include unpacking and packing equipment )
Asked his wife and him to check them and did they find them acceptable which they both did, wont lie there was a small
amount of spotting but it wasn't caused by lack of flow.
