I just tried the OMS in a plastic Gatorade bottle trick last weekend, after having only done the wipe and lube routine, and I was blown away by how easy and effective it was!
I ride in areas that are pretty sandy, and there's always gritty crap in my chains that doesn't come out with a wipe down. I took off the chain (I had installed a wippermann) dropped it into the bottle, and shook the crap out of it for a minute. I let it sit for about ten minutes, then shook it again. When I fished the chain out, I could not believe how clean and shiny it was! And grit free!
I wiped it off and let it dry for a bit, then put it back on and lubed it. My drivetrain is incredibly quiet and smooth now!
Highly recommended!
