Hi Bazzy - I accidently deleted my letter but I can show the salient points
Hi Everyone at (place/street name)
Just to let you know I am now using the wfp system and not ladders.
Main reasons are it is very effective for cleaning all of the frames and glass by washing them with purified water
It takes a couple of cleans to get all of the dirt and any chemical residue off, and there may, at first, be some 'spotting' where small marks remain. These will disappear after a couple of cleans
For me, it means being much safer because I remain on the ground.
For yourselves, it enhances your privacy, as well as providing excellent results.
If you have any questions, give me a call.
hope this helps
