You should probably take it apart as well. Put all the small pieces in a pint glass (or something) with hot water and pbw. Place the dip tube in the keg filled with hot water and PBW.

@ mtyquinn I can understand the logic with a carboy - avoiding temp changes, etc.

My logic with corny kegs is - Stainless Steel - hotter = better. I did not think about the solubility of Oxygen though... curious point... hm... We need us a Scientist!

+1 to taking it apart. I rebuild my kegs almost each & every use. (Only *sometimes* do I skip it - for example, if I cold crash a beer in a freshly rebuilt keg, for only 5-6 days, then I immediately clean it with Oxy and refill it with StarSan - then I will reuse it one more time before I rebuild it.)

I go through a lot of O-Rings - but when you buy them in 200pks from McMaster - you stop caring about wasting a $0.02 O-Ring in exchange for the promise of a cleaner keg. Plus - I add Keg Lube to every single O-Ring and poppet, every single time. I do not like hissing posts or leaky kegs. Not in this house, nossir.

PBW really is the best cleaner for dirty kegs. Cascade also does a great job.

You aren't supposed to use those until after the keg is clean.

Oxyclean and hot water inside, Bar Keepers friend on the outside. They will be clean and purty in no time.
The yeast knows what it's doing.

I've found that just flushing the dip tube with co2 and oxy solution is inadequate. I was amazed at the gunk I got when running a diptube brush through tubes I thought should be clean.
Reality is an illusion that occurs due to the lack of alcohol.
Give a man a beer, he'll drink for the day.Teach a man to brew, he'll be drunk the rest of his life.
I have 8 carboys, 8 cornies, 5-1 gal jugs, 200 wine bottles, 10 cases of beer bottles and a nice assortment of flip tops....My goal is to keep them at least 50% occupied
