Rubbish, you cant scratch glass with a SS scraper nor will any water fed pole with aluminium fittings on them, the only way glass can be scratched is with a contaminated cloth or brush head.
I have had this before and demonstrated in court with a piece of glass and a stainless steel scraper in front of the judge, he could clearly see that the blade could not scratch the glass.
Hence the case being dismissed.
This happens often on builders cleans and the architects or site project manager generally blame the window cleaner , 9 time out of 10 the glass was already scratched.
an example, architects used to recc the old Over the Top 6" ss scraper to remove debri from glass prior to cleaning, in one particular event the project manager try to blame the scraper, i said call your architect over, which he did and he said to me and the manager only a ss scraper should be used and he mentioned the one i had, he said no way can you scratch glass with one of them , I said you mean one of these, Yes he said , well thats what I used, so he inspected a further 20 glass panels before we touched them and found that 12 were badly scratched, the project manager was sacked. so don't let the big boys blame you, stand up and be counted.
