Not that I do a lot of work that needs scrims now due to WFP, a couple of large microfibres and a couple of scrims last me well over a week.
But when I was full on traditional, 3 scrim (didn't use microfibre then, wish I did though
) would last me all day, with ease.
My belt had two pouches, one for my dry scrim, one for wet.
On the wet side was also the BOAB.
To begin with both scrims are dry (of course) as the one scrim got wet it would stay in the 'wet' pouch and be used for frames, sills and so on. If it got really wet and dirty I would wash & rinse in a fresh bucket of water and then wring it to within an inch of its life
.
The only time I changed the dry one over would be if it got too damp (or dirty).
If I needed to dry a scrim out I would put it on the dashboard, tuck it tight into the gap where windscreen meets dashboard and between accounts put the heater on full blast.
Or use it as an excuse to sit in the car to warm my hands up while I dried the scrims
Now I know scrims obviously get dirty, but you can still get a lot of mileage out of them if you are only detailing.
If you are using them to buff clean small panes then you need to change to a clean scrim regularly.
How many of you window cleaners of SEVERAL YEARS EXPERIENCE find you only need to use a couple of scrims a day?
When you start out you go through scrims like there is no tomorrow, and can't believe its possible to only need one or two a day.
But as you become more skillful, the amount of detailing you need to do drops a long way, and you don't need to keep changing scrims just for sills and so on.
