Dave,
I'm no fan of the Freedom Trolley, because I think it's big, bulky, overpriced and has been mis-sold to users who it's not suitable for.
Anyway, what're you doing?
Tops only or 100% WFP?
If you're using it as a trolley system I'd recommend 'tops only', but if you're using it as a van-mounted system, then do 100% with it.
That apart, you've got to go over the top on first cleans, especially when you don't know what you're really doing.
If you do the following; you'll get good results:
1. Wash the frames REALLY well.
2. Rinse the frames.
3. Work on the glass; you don't have to go overboard; just wash it twice quickly.
4. Move onto the next window repeating the process untill all the windows are cleaned.
5. Return to your first window and rinse the GLASS only.
The thinking behind this is:
It's very easy to clean glass, especially the 'sheeting' sort with a WFP (the beading sort cleans well too mind), it's the top frame that generally lets you down and drips dirty water over your windows.
So by cleaning all the frames and windows first, then returning to the first window you've cleaned to rinse the GLASS only, you've bypassed all the drips.
It is a pain, I know, but this will produce good results and subsequent cleans will be much easier; less fannying about.
I hope this helps, but ANYONE, correct me if you know a better method. I've only been using a WFP for a year; doing tops only mostly; so I'm no 'WFP Guru'.
I'm quite happy to be 'taught' by those who're more skilled than myself.
