3hrs to clean, well if you take the 1hr off from talking then it would have been 2 hrs.
I found the scrubbing pad Ominpole Sell was Top Notch for this job, as it has not been cleaned in 18 years. Once i changed from the brush to the pad I really noticed the change in speed I was cutting through the grim. Thou a scrapper on the end of the pole would have been even faster. Thats my next investment.
Anyway i then went over again with the brush to finnish off and 99% of it was removed, there was some bird stuff that I could not move off the frames.
Overall they seamed very happy and they are going to book me again for next year.
