Did customer today.
He installed and services our boiler.
Never works out monthly as he's always decorating or adding more bathrooms in his house.
Haven't been for 4 months.
Did all outside windows and some inside.
Did outside and inside of bathroom windows.
Noticed a diagonal faint scratch about 5 inches long on outside of one of the bathroom windows.
And then on the inside of another bathroom window there was a cluster of fine scratches about 3 inches long, vertical scratches.
These are new windows, I used waffle clothes and a trigger spray bottle with pure and gg3 inside, windows had plaster dust on the inside. (no razors used by me).
Outside windows I used a gardeners super lite brush soft flocked one, pure water wfp with a touch of gg3.
I scrub window up down then rinse side to side.
Couldn't see how I could have been responsible for scratches either side of glass.
Am I wrong?
Customer was ok but stated windows were only a few months old.
Just felt awkward.
