I don't get this - sorry
With our job you can't actually see the dirt coming off the glass unless it's a baked on poo. So how do you know it's cleaning 25% faster? You can't. Is the water running down the glass 25% faster - doubt it. Are your arms going 25% faster?
I think the claims are well over the top.
Rinsing on the glass saves time but you won't get those kind of gains.
Johnny has been pretty honest so far and hasn't claimed vast improvements from his own product just that it can help sheeting on some glass and seems to add a shine.
It is a funny thing Dave, and really hard to explain, but for every positive comment on here though I've had about 5 emails from people experiencing the same thing so it's definitely not a placebo effect or just coincidence.
It's one of those things that you feel more than you can explain.
For me as well as the cleaning power, I really notice the saving in speed on the final rinse. Wheras before I was rinsing with the brush off the glass in a zig zag motion to flush the water off, now I can just do a very quick rinse of about the top third and then it all just rinses down.
It's not a very technical explanation, lol but it's the best way to explain it without seeing it in person.
