Vacaway's Spot-n-Boost and Cyclone products work well with filtration lines. I usually keep my steam vapor machine fired up as a back-up on an as-needed basis.
Mike: Yes it is high foaming. I was thinking enzyme pet cleaners were more specific to the bacterial break down of urine.
Mark: Spot-n-Boost is my "go to" spotter for sure.It does a great job. I just need to order larger quantities as I seem to go through it fairly quickly. Haven't tried Cyclone yet.
