I have tried pressure washing glass before at 3000 psi. I have never seen a 3000 psi pressure washer clean windows like this. It's never as spotless as traditional squeegee Are you using a reverse osmosis DI filter? Can this clean off silicone residue, stickers, cement splatter, bird droppings and caked on dirt? Please show us before and after shots of really dirty window. Is this more effective than agitating dirt with boars hair brush with watered pole or traditional squeegee?
It definitely can’t clean, there will be no before or after pictures, because then it would make pointless this video. Just try to Clean with pressure washer any dirty glass, try with car windshield, you can even apply non contact cleaning detergents, and then pressure wash again. What can I tell you, hands are given to you by God, try traditional cleaning and then compare 😊
I am sorry to criticize but 30 years experience in window cleaning and pressure washing tell me this will only clean .....clean glass. And in doing that, it still wouldn't do a satisfactory job. I would love to be proved wrong.
