Chain cleaner

Right guys and girls, I want to know how/what you use to clean you chains.

I had a KettenMax cleaner but thought it was pants so threw it out and have just be using degreaser/paint brush combo since. So I'd like to know if there is any good kit out there worth trying. Suggestions please.

WD40

Use kerosene if u can it will not harm rubber and it cleans great.

Wurth brake and chain cleaner is awesome, by far the best I've used. Mind you one can only lasts 2 good cleans.
