Sanitizing your kegs is fine but is by no means enough. Every so
often you still need to thorougly CLEAN them.

Once per year I completely tear down my kegs, and soak all the parts
in PBW, scrubbing if necessary. The same goes for the taps. Once
dry, I put it all back together, then mix up about 3 gallons of PBW
and put it in the keg. I pressurize, then run this through the lines
to clean them. Then I use regular water and push about three gallons
of that through the lines to rinse them.

You can't sanitize a dirty system. It needs to be cleaned first.
