Great advice guys I did spend a while doing all the small gaps between glass above frames etc I actually thought I over killed it as it was a first clean going back tomorrow to sort but fore armed n all that,, so I will give it another good going over going forward and a good rinse on way back so in affect it will have had 3 good goings over surely that should be suffice,,, just poopting it a bit lol just need to keep the faith,, I supose folks, helps the manager is on board with me after explaing not using ladders etc, and pinged him over method and risk a a explanation that it might take 2 to 3 cleans to get it rocking,,, so will hope fully meet with him and show him round van etc how thing's work and he seems to totally get it but it's sweaty collar time for me gulp, 🙄
Oh just out of curiosity I had my flow at 40
