Oil Catch Can Baffle Options

[Coomer]

Hey guys, I'm going to build oil catch cans for my cars this weekend, and I've been doing some reading, and some how-tos say that you should use a baffle. Someone mentioned using a lufa(you know, the body scrub things that chicks use.), someone else mentioned a Brillo pad I think...I know a couple people mentioned not to use steel wool. Someone else on Honda-Tech mentioned this:

I used one of those poof-poof things you find in The Body Shop. Cut off the string around the middle and voila, perfect baffle material, cut off however much you need. One poof-poof was enough for 2 catch cans. Buy it at a dollar store - literally $1.

...whatever that is.

Anyway, what exactly does a baffle in an oil catch can do? Make it so that the oil vapor gets trapped in the baffle and doesn't make it back to the intake?

Also, what should I use for a baffle? I worry about using just anything, because I don't want tiny pieces to make it into my intake and get sucked into the engine, possibly causing damage.

Any ideas guys?

Anything that goes in the catch can is basically there to catch moisture and vapors you don't want recirculating back into your system.

Everything you listed sounds like it would get the job done. I haven't heard many warnings of things to not use. Heard someone even joking about using Cherrios.
