I gave this product a try on my chain and sprockets today. I'm impressed! The instructions say to spray it on and let it sit for 60 sec. I did that, then wiped everything down with a rag, no "scrubbing". I wanted to see how effective the solvent was and how much elbow grease it took to get things clean. I used the rag with minimal effort to see how much crud was left over. It works very well as you can see in the attached photos (no lube was applied yet in these photos). Recommended. I finished up with DuPont Teflon Chain Saver lubricant. :thumbup: I realize I should have taken a before picture, but forgot to do so. The chain and sprockets had black buildup on them...they were dirty.
