that's my considered opinion, there are many people don't rate the job that wfp do; there's a lot of marketing hype and vested interests.
Have to agree mate, but....this wfp thingy is open to many different factors and situations in order for it to work correctly. It does clean most types of glass to an absouloutly brilliant finnish
but only if conditions are good for it to do it. Strong winds will blow dust and all sorts of s hit on to newly cleaned wfp glass, it will dry spotted, but most cleaners will be gone by that time and will never know or realize its not too clean when its dried, if they get complaints they will go into denial mode......they just dont know where they are going wrong. Hydraphobic glass.....where the pure water beads instead of sheeting will also give lots of problems in the form of water spots when dry, especially if the building is close to heavy traffic and all its spray. Guys who keep their pole and brush on the van roof in winter without protection, think of your windscreen in a wet december day...... in less than 2 minutes after scooshing the windscreen, well you have to do it again or you simply cant see right, some cleaners just dont realise that their brush head is absouloutly filthy when they arrive at a job, then they go and clean the windows with the mingin brush, still it is pure water so itl be ok, :
.look I could go on and on, but my point is it really does come down to experience with wfp. Traditional is safe in the sense that you can see what is not right if anything after cleaning, wfp is wing on a prayer even to the most experienced.....fact. PS I am 85% wfp 15% trad and 21 years in buissness.
