Good stuff, cleans well. I typically need to reapply about every 75-100 miles, following the directions and letting the liquid dry on the chain overnight and wiping off the excess in the morning as necessary. The stuff pushes out the grime pretty good in the application process, but chain will still need to be removed and washed eventually. Every 500 miles it is best to remove the chain and wash it in a small amount of xylol (paint section at home depot) to completely refresh the chain to a like-new state. Same wash routine I've used for years, but T9 keeps the chain much cleaner than most wet lubes.
