Not really a trick but you may want to try Lexol, they make the best leather cleaner and conditioner that I have ever used(tried mothers, meguiars, 3M,etc). Also, since the lexol cleaner and conditioner are seperate bottles I have noticed that the cleaner is more concentrated and tends to remove stains better than meguiars IMHO. Although the price is a little steep, it is definitely worth it.
