Keg/beer line cleaning sanity check

Hey all. As I went through my kicked-keg-cleaning routine, I thought I'd run it by you all and see if I'm doing anything I shouldn't, or not doing anything I should be.

When I kick a keg I also clean the line for that keg. Here's what I do:

1. Mix 1 gallon of BLC (1Tb to 1gal of hot water) in a spare keg.
2. Pull kicked keg, hook up spare in its place.
3. Turn on tap, pull a pint or so of BLC through.

I leave the BLC in the line while I move on to the kegs:

4. Rinse kicked keg with hot water.
5. Hook up jumper and run BLC from spare keg to kicked keg.
6. Hook up jumper and run the BLC back to the spare keg. This makes sure both diptubes have been cleaned.
7. Rinse both kegs and repeat 5 and 6 with clean, hot water.

Kegs are now clean and rinsed, go back to the tap.

8. Hook up keg with hot water and pull several pints through the tap.

All told takes about 15-20 minutes start to finish.

Mostly I want to make sure I'm not doing anything horrible by using the BLC in the kegs. I don't think I've read of anyone else doing that.

Thanks,

Line cleaning sounds thorough. The only thing that I do differently is disassemble the posts and remove the diptubes for cleaning, and I run starsan through my beer lines. Since it's acidic, it should remove beerstone. BLC seems too expensive to use as an everyday line cleaner.
