New cleaning method?

[mbryan]

Has anyone ever seen this? It looks like they just sprayed chem and left without washing it off.

Washing the chemical off cost extra.

We have inadvertently done exactly that. Once we chem-saturated hugh buildup on impossible fan impellers which had resisted high heat & high pressure, allowed to dwell, then forgot to p/w off. Next visit 3 months later the fan impellers were completely clean - didn't even need the p/w. Go figure.

Definetly looks like some caustic was left in the duct. Have to be careful with that kind of stuff,just a tad dripping into somebodys lunch could cause major problems. Rinse and repeat.

Maybe they forgot to add the foam .

No thats the Oh I forgot to put gas in the machine, lets go get some, and now I don't feel like going back because the bar is right here next to the gas station cleaning method.
Am I right?
