Cleaning a mattress

So last night we came home to find that one of our dogs got sick on our bed. The stain came out of the sheets, but is there a way to get it out of the mattress without ruining it?
I have a Martha Stewart "household bible" and it says not to get your mattress wet, b/c it will ruin it.
I don't know what to do..I don't want a puke stain on our mattress, and I don't want to ruin it either.
Any tips ladies?

Thanks!

We had our mattress steam cleaned before.

I would check with a cleaner to see if it works in your case.

Re: Cleaning a mattress

how old is the mattress?? it may still be under warranty. OUr sleepy's matress has a lifetime warranty that as long as we have the mattress pad on it, any stains they will come clean.
