Helped a friend out who spilled a whole bottle of wine on her sisal. explained the risks
but it was do or die. Quite profiled so couldn't get decent suction, used microsplitter, then enzyyme,
then sod met, extractimg with acid rinse between each, carpet vastly improved, it was latex backed and stretched.
After a final mist with sod met the next day, all was good after a re-stretch, and still friends.
Wouldn't have the bottle to do it on a custy's carpet tho
