FAQ's about WFP Use

How much of the frame should I clean?How much of the frame should I clean?
It's up to you, but with the top edge of the window, it can be crucial to your finished job knowing what to clean and what to leave. If you start to clean the frame make sure you get it clean, as any dirty water will work its way down onto the glass. There is usually a natural division. Remember, whatever you brush will run down onto your window, so don't take on too much. The first clean will always take longer because more of the frame will need to be done.

Some people warn there clients that there might be the odd run down from the frames the first clean - if you get it right, this shouldn't happen.

You will find that some windows are trickier than others - time will tell which windows play up!


I seem to be spending just as long as I used to - where is the time-saving advantage? I seem to be spending just as long as I used to - where is the time-saving advantage?
You will probably save no time the first month because

a. You are learning as you go

b. You will have to explain the new system to your customers as you go and also every Tom, Dick and Harry who walks past

c. You are having to re-learn every window - it does take time

d. You are having to learn where to run your hoses around the building. Getting this right will save you up to 10 minutes on each job.

It will improve, just be patient. As each day goes by, you will get slightly faster until six months later you will not believe how fast you are!



Some people say it will never do as good a job - is this true?Some people say it will never do as good a job - is this true?
In many cases we find it actually does a better job. Correctly used it will always do a good job. We are still amazed at how perfectly it cleans. A good way of checking the efficiency of your technique is to do you own house and then go and clean the insides. You will learn a lot.



What will the system clean off and what will it not clean off?What will the system clean off and what will it not clean off?
It will clean off the following:

Bird mess - it is essential to pre-soak this with the purified water and leave it to soften. Sometimes you will have to do this several times. You will get used to looking out for it and giving a quick squirt of water when you first arrive. Then you will have to scrub and scrub! It can be very tough!

Snail trails - every window cleaner knows how stubborn these can be, but with the brush it's straightforward. Your first brush down will highlight where they are then just scrub and watch them melt away.

Caterpillar trails - these are usually some of the hardest of things to remove but pure water just melts them. A second scrub will easily remove them.

Fingerprints - your first brush down will highlight them then just concentrate your scrubbing on them.

Putty marks - a pre-soak and scrub will usually remove most putty marks on glass. Allow putty to harden for a few weeks before working on the window.

Fresh plaster and concrete - if it is only a few days old, pure water will usually dissolve even concrete (be careful to rinse brush head off afterward).

It will not clean off the following:

Dried on egg - trick or treat time! This dries like glue and the only thing that will ever remove it completely is a scraper.

Silicone or masonry sealant - scraper time again.

Paint - scraper time again



How do I clean over a flat roof?How do I clean over a flat roof?
We virtually never have to get on a roof to clean the window above. If the pole is long enough, you can usually just reach over either straight on or from either side. Even if you have to do this from either side in two hits, it is quicker than getting your ladder off your vehicle.

What happens when there are railings across the bottom half of doors and windows?What happens when there are railings across the bottom half of doors and windows?

This depends on the railing width. On most railings, you can wiggle your brush head between the railings and clean it a section at a time just as you would with a squeegee. You can also apply this technique to balconies with railings. If they are just too close together, you can clean the top half as normal and just rinse off the bottom half using the end of your brush to rub any stubborn marks off. On some commercial jobs, we have been asked to quote for all windows apart from patio doors with railings. Discuss what you are able to do with the customer first as most are very accommodating.


Many people, including our customers, say that the glass stays cleaner longer - why is this?Many people, including our customers, say that the glass stays cleaner longer - why is this?
Firstly, because over a period of time, the frames gradually get cleaner, leaving no dirt for the rain to wash down onto the glass.

Secondly, because it washes so efficiently with no detergents, it leaves no detergent residue on the glass, which would otherwise attract particles of dirt.©
