I’ve gotta be honest, I was a carpet cleaner for almost 13 years and of all the methods I’ve done (chem dry bonnet cleaning, chem dry hot water extraction, steam cleaning, encap) the method you’re using seems to be bottom of the barrel. (no offense please, thats not what I intend)
Encap is easy. There is no extraction, no need for heavy equipment, yes you have to fill a tank (I would be using a cornelius keg, but you could use pump sprayers) but thats easy enough, no need to worry about protecting adjacent areas just watch where you spray and wipe up excess solution.
Strange reflections.
My son is learning WC. He has returned from 4+ months in the Philippines to work his seasonal job at Fairbanks, which is 600 miles away. In his spare time he will be finding clients for us and cleaning windows. I will be going to Fairbanks every month for working vacations.
Not sure why there is squeaking. The glass was real wet and the rubber was Moerman soft. Maybe because of new rubber or because the cold temp was in the mid teens or maybe the 25% windshield washer fluid that was mixed with Waxie Liquid Squeegee?
A couple of observations if that’s OK. Most of the squeaking at the start is rubber tip against rubber seal. I get this quite a lot over here. I can minimise it by making sure that when soaping up the glass I also run slip over the seal so rubber against rubber also glides. The danger with this however is that if you overdo it you can get seal bleed. Towards the bottom the squeaking is definitely on the glass. Wet AND slippery is the key to your solution. When I first started out with Wagtail a few years ago my solution was GG4 which I’d used primarily with straight pulls using an Unger 0° on a pole. Transitioning to Wagtail I found GG4 simply didn’t have enough slip. Current solution is ECover/IPA (Isopropyl) mixed at 70/30 and applied from a squeeze bottle directly to the wet scrubber…
I’m guessing that the windshield washer impacted the good glide of the Waxie Liquid Squeegee.
My guess was that the windshield washer fluid was at 25% but it is probably higher. My first mix was 20% was freezing so I added more without measuring and it is probably around 40%.
First, good video. Your son has good fanning motion. Good grip too, looks like fingertips.
You know what may be the cause- 2 things.
Channel size. Try a smaller channel than you think you need.
Travel Stroke. 0:01, 0:07, 0:11
As one travels up, what is happening to the rubber? Drying off.
Great for standard squeegee.
But what does the LQ like? Wet wet wet.
Try this: Instead of traveling up ALONG the soap, travel up THROUGH the soap. Wets the rubber as you travel.
