Wow that is really neat

Great idea! Hard drive magnets would work perfect for this... Until one slips out and leaves a nice scratch

I'm a big fan of the one I made using this one as a model.

Scrubs it out in no time a minute or two maybe. I think Noble Grape sells the actual "Carboy Cleaner" for around $30.00.
It wasn't  hard to make though a SS rod with a microfiber cloth attached to one end with a funnel to guard it from hitting the carboy opening. Might have cost me $5.00 to build.   

Also works great on kegs!

Yup. I have an actual carbon cleaner. Love it.

I actually do it the lazy way and soak my caboys in oxyclean. Uses a lot of water but it works very well

[Chris Craig]

I use a combination.  I usually fill the carboy with oxy and run-off water from a brew day.  I'll let it soak until I feel like finishing the job.  I find that sometimes the krausen line can be quite stubborn even with the carboy cleaner.  I don't know if I should be using something other than oxy and water with it, or if I should be using PBW, but the soak definitely helps.
