I use undiluted fenwicks to soak it in, then give it a good scrubs with a hard brush again with fenwicks, dry with a cloth, allow to dry and then apply the squirt, allow to dry, then recoat with squirt the following day.
After you do all that you can just scrub off the squirt and reapply without having to soak etc after each ride or two.
Loads of folks on here have loads of weird and wonderful routines.
Make sure you clean the jockey wheels and rings too!
