I have an idea'er...
with a razor "surgically" slice off as much as you can without slicing fiber
Use mineral spirits to keep the blade clean and wet/lubed with mineral spirits
Once you've sliced as much off as possible, now use you hand tool and a can of WD-40 (maybe three ) to use as your "mini solvent pressure washer"
WD will emulsify the roof goo
Spray at an angle across the goo and right into your recovery tool
I discovered quite by happenstance how effective WD is at removing roof goo.
Years ago I was sealing a chimney flashing one afternoon .
Of course i got the sticky chit all over me
(my Mother, God rest her soul didn't call me "Pig Pen" for nothing)
I went to the carpet truck and grabbed some Flex and a towel....it removed very little from my hands .
Then grabbed the D'lime...not much there either.
I tried a half dozen chems and spotters with little to no success .
Then i remembered one of the Old Salts mentioning WD as an effective carpet spotter.
I grabbed the can from the tool box, sprayed my hands and the goo wiped off my hands LIKE MAGIC... :shock:
FO-REEL!!!
The angled spray and immediate recovery into you hand tool vac slot will prevent excessive solvent from permeating and spreading the emulsified goo.
no rubbing, no scrubbing, no saturating..... no pile distortion
Looks damn good on the drawing board, don't it???
whether it will work as envisioned.... I haven't a clue...
