Do you think that one of the carpet cleaners would be too strong?
FWIW, if using Resolve Carpet cleaner elsewhere, try your best to keep overspray to an absolute minimum. I have some white residue, like salt stains, on the interior plastic. Unable to simply wipe it off.
I have a light exhaust soot dusting in mine and haven'e decided to do anything except put the vacuum nozzle near some of the worst of it.
