Very dirty windows with WFP?

I am interested in getting into a wfp with a job that I have coming up. The building has about 250 windows split equally between the first and second story. The problem is that they havent been cleaned for over 5 years so they are very dirty. So my question is whether this is a good job for a wfp or should I use the traditional scrubber and squeegee? Also, is the starter kit that window cleaning resource offers up to the task of such a large building? The water here isnt real hard but I havent checked it with a TDS so I dont know the exact ppm.

Yes, you can wfp that job. Try it first with just pure water, and if that dont look good, grab an extention pole, and have someone go in front of you to scrub them with the scrubber…then go and use the wfp to scrub and rinse again. You will still go faster this way. On the bottom floor, do the same thing, but instead of using the wfp, disconnect it and rinse with pure water.
Getting that pole will be a great investment for you in the long run anyway.

Alright, thanks for the help.

yes to wfp but with tap water !! what your tds ?? tap water will have spots when it drys !! itis one of each or both. you’ll use a lots of pure water and time. do it in the shade. work real slow on the tap water and rince and rince !! also winds should be 10 mph or less !! earlly moring amd late evening with nobody around to trip on hoses and etc. you’ll save 60-70 time with wfp. get the bottom ledge extra as it will weep. wfp with tap then strip andthen pure water wfp. price it a little high. get them on a twice a year at a lower price. not as much work!!! hope this helps,stan

No offense intended…why tap water? Not sure why you need to work in the shade, the sun should help to dry it much faster, and unless winds are kicking up dust on the glass it should be fine. I really dont see why he should use tap water tho.:confused:

If the windows are just dirty and not stained or etched, the wfp will work fine , assuming that the frames are in decent shape
When faced with a particularly dirty job that for whatever reason I would rather not squeegee, I just hook the wfp up to tap water and wash the heck out of everything first, Then go back and wfp with pure water, This saves your di system and if there’s a lot of outside outlets a bit easier, also if you watch the way the tap water runs off the glass , after a while you will learn to spot( pun intended)which ones are going to be a problem

Hmmm…okay. I understand.

Rather then doing that…

to answer on tap water its cheap !! some x you could start farming on the sill !! then you can see what you’ve got to work with !! as far working in the shade the spots don’t dry as fast. and it easyer on me !! two and three story buld you have 25 to 35 ft of pole in the air. lose control and who pays ?? get the client to do the 2 x a yearthing. talk to them after you clean !! reduce the price a little. works for me every x !!!people just don’'t know how diry there windows are !! one side of the builing will be dirty than other side. dependss on what driveing rain was from !! stan

I do an awful lot of beachfront properties that have the saltwater and sand
caked on. (Southern Calif.) I do a regular water wash with the WPF and then use the D.I. to polish them off. Comes out perfect every time. Also on a different note, I bought a couple Corba 2-way radio’s ($39.00) what a life saver!! I can let my helper know from the inside which windows are spotless
(from 3 to 4 floors up) and which one’s need another scrubbing. These radios are also great on large homes, commercial properties, etc., best investment I every made.
