That is the same problem I had with my new foamer on Tuesday. I was so disappointed to fall back on my 5 gallon foamer. Tommorrow, I have 2 daytime jobs, so I will close my chemical valve, then open it 1/2 turn untill I get chemical.
I will also try my KC anti-chemical sleeves and my new purple gloves.
Maybe I'll even use cold water again.
Last Sunday I used my really expensive magnetic scraper, worked great on a never cleaned duct. I need to get a longer handle though.
