TLDR Version: B+, better than Gojo I've done the Gojo (no pumice) scrub the past 2 years. This year I thought I would try Budda Belly instead. So I changed the oil last weekend and then scrubbed the belly. I will definitely use this next time vs gojo. I think it could be a little better though. Pros: Much easier to apply. Just spray it on vs trying to grab the perfect sized "glop" of Gojo that will be enough to actually clean it but not so much that it falls right back on the floor or you. It seems to break the heavier oil down quicker than gojo (but not fast enough). It smells better If it falls on the floor it doesn't seem to be quite as bad on the concrete. I can still see spots where some of the gojo fell onto the concrete the past 2 applications. The smallest sized bottle seems to be enough for the piston single. Not sure if would be enough for a TBM Avenger LOL! I had about 1/4 left over from the smallest bottle. A second pass half way through the year would be far less mess than another gojo scrub. I'll use the remainder of the bottle right before the annual in October. Neutral: Being much more viscous than gojo I was hoping that as it was sprayed on and wiped off there would be less residue around each rivet...nope...same as gojo. I was hoping it might do better on the few deeper brown oil stains in the white paint - nope...same as gojo. You will probably use about the same number of shop towels using either method. Price. Cons: I wish it would break down the heavier oil quicker. It is marketed at being a great product for on thing: scrubbing oil off the plane's belly. With that I figured it would just mean give it a squirt or two, wait a few seconds and wipe it all off. In reality the heaviest spots required a first pass to get part of it and the second pass was enough to completely get it all. The spray nozzle could be more practical given its #1 use...laying under a plane and spraying up. Eventually there isn't enough fluid in the bottle and you then have to start tilting it back upright again to get the last 1/3 or so out.
