Don't use resin,my tapwater comes out at just over 30ppm and
problem windows I just squeegee dry.

Which part dont you believe,i dont use resin or i dry windows with
a squeegee and to add up to 2nd floor aswell.
Are you telling us 030ppm does a good job? Rubbish! And as for blading pure, sheesh.
Right let me educate you,i have been cleaning this way for nearly eighteen months
now and yes 30ppm can give decent results for example on new build properties
i clean its never a problem,i squeegee dry the down stairs as a precaution,its
only a very quick drying as its only water and this time of year its a doddle.
I clean an awful lot of old properties with leaded lights and never have a
problem with these either with 30ppm
Older style semis can be a problem so i generally dry all windows
after cleaning upstairs using a unger pole couple of straight pulls its
done.
Windows with the pretend leaded strips are the worst so i tend to avoid
these properties and only have a few on my round.
Must order a reach around from gardiners,i used just use a optilock for
wfp was easy just to pop brush off and plonk a blade on,but since
ive bought the clx it has slowed me down a little.
Anyways believe what you like,i even include the drying of the glass
in my pricing so even though im a little slower than straight wfp it
balances itself out and with the drying of the glass the customer thinks
they are getting something extra for there money compared to other
splash and dashers in the area.
