Just been reading Lee's post about going WFP and didnt want to hijack it so hence the reason for this post.
I will be changing my round over to wfp within the next 1 or 2 cleans and have been getting ready by doing the following.
Making sure all the tops of the frames are mint - plus the sides and the sills
Using pure water in my bucket with a weak mix of ettoire squeegee off
Doing conny windows with p/f trolley so customers can have see how clean they come up
Would you give them a letter explaining how WFP works / explaining the benefits or dont bother and just get on with it.
Anything else I can be doing now
