I have used this 3 times since purchase, I have been very pleased with the results.
3 points of advice:
1) the spray comes out very fast, you want to be standing back a bit.
2) put some old rags / new paper down as grease will start to drip off very quickly
3) use in a well ventilated space, there is a strong smell that you will want to dissipate.
Overall, impressive performance - especially in hard to reach areas.
I rested my bike atop an open garbage bin and made sure the pedals could rotate freely, and then sprayed Finish Line Speed onto the chain,cranks, and cassette,etc. The spray is strong (the smell is strong and similar to acetone so I won't be using this inside). The gunk really just came right off and made the drivetrain bright and shiny. I don't think I am going to get but two cleanings per can so it is a little expensive, but I think you would have a hard time finding an easier cleaner to use.
It works very well. It gets all the grease and grime off of my cassette and chain quickly and easily. I was shocked the first time I used this stuff at how well it work. No scrubbing or brushing required. The grease and grime just runs right off after spraying the chain or cassette with this.
Do I wish there was something a bit more environmentally friendly than a single or dual use (depending upon how much one uses) can of spray degreaser? Well, yeah! Maybe they could make it in a larger can. Maybe 36 or 48 oz.
I spray this on my chain with a rag behind it and gunk flies off onto the rag. Then a wipe down of the chain, and it is ready to be re-lubed. I have read reviews of people spraying this on their cassette. I don't recommend that as it can get inside. I spray it on chain floss (or a thin piece of cloth) and clean between each gear with the rear wheel off. I have had mechanics tell me my bike is cleaner than they will get it.
This stuff is magic for blowing our grease and grime from places a brush won't reach. However, if you're like me, you'll go a little crazy with it and before you know it, the can's empty. If used sparingly on a few places on the bike, you can stretch it out over 5 or more washes.
Finish Line Speed Bike Degreaser works great and I'm glad it tried it (ordered it on a wim to put my order $ over the amount to allow free shipping), but it's an expensive way to clean bike gears. I'll continue to use my old fashion scrub brush and degreasing dish liquid for regular upkeep and save this for special occasions where the gunk is really embedded.
takes dirt and grease immediately off the chain, frame, rims.
Does not penetrate as when I soak a chain in diesel fuel but otherwise the surface of the chain
is virtually spotless.
