How did you modify your bucket blaster to clean your taps? I just brought one as well and want to do the same thing?Clean the lines every time you change the kegs. Give the taps a thorough clean every couple of months. Perhaps a bit more frequently.
I've just gotten a Bucket Blaster from KegLand and have added a few bits so I can clean my lines without wasting CO2. I think that'll help me keep up the cleaning.
