It’s actually the other way around.. Pre treat with Folex, and use the D101 as the more broad approach cleaner. You’ll quickly get a feel for how they’re both geared to work that way.
-Further explanation: The Folex can sort of, actually it can do what the D101 can do if you felt like using it to clean the entire carpet of a vehicle, however I would strongly advise against using the Folex in the same method as you would use D101, meaning you don’t spray and agitate/scrub Folex, you instead want to spray, then immediately lightly dab the product into the fabric with your fingers,[I recommend wearing HD nitrile gloves] then immediately blot/dab/mop/wipe clean with an absorbent towel. [IMO cotton terry towels work best]
Basically you want to follow the directions with the Folex, and that means no scrubbing, especially with a brush. It sounds crazy, but you’ll have subpar results if you scrub.
-D101 on the other hand can’t really do, or do effectively or in a reasonable manner what the Folex can and sometimes it’s not even close… For example there’s times where you’d have to use D101 at full strength for it to even begin to remove stains and even then there’s no way D101 would be able to do it without scrubbing the way Folex does. Plus it’s a hazard to use D101 undiluted especially on interiors, let alone trying to breathe through the fumes it would create. Not advisable.
