Extremely dirty subfloor after removing carpet and pad

[Michael S.]

I just ripped out the carpet and pad at a new place I bought, and the subfloor is very dirty.   House had a really bas smell, probably from pet stains that soaked through carpet.  Carpet was heavily stained.  Basically, I don't think anyone ever vacuumed or steam cleaned the carpets in 10+ years.  I will sweep out the floors really good tomorrow, but I almost feel like I should mop the subfloor.  Is this a bad idea?  Is there a way to get the floor cleaner than just sweeping it without getting it wet?

I have a carpet guy coming in about 3 days to put down the new carpet and pad.

Thanks for any suggestions!
