I got a guzzler several months ago and forgot about it as I have my reliable real shammy and a cool soft rubber scraper thing for water removal on flat spots.
When I came across the guzzler last month and took it out and used it, I was very impressed!
The guzzler is far better than a shammy.
The guzzler easily picked up water and left no streaks as the shammy does.
However, I used the guzzler once on a very clean and polished car and I hung the guzzler to dry.
When I used the same now dry guzzler again on the same car, it did not seem to absorb water as efficiently as the first time I used it.
I have not washed the guzzler with MF cleaner and no dryer heat yet and maybe it needs to be washed to regain its full absorbency.
But on my standard MF towels, the first use of a MF towel is the best use and a washed MF towel, washed correctly, is not as good as a new one.
Clean your windows with a brand new MF and then clean another window with a properly washed MF towel and the washed towel will not absorb as well and will leave more product on the windows to air dry.
I do plan to use the guzzler instead of a shammy going forward as even a used guzzler seemed to work better and with a lighter touch than a shammy.
Shammy, who would have guessed that is a real animal!
