I recently had a sewer pipe under my kitchen in the crawlspace severed and leaking. It spilled quite a bit of "waste" into my crawlspace beneath my house and boy does it smell like sewer! The plumber told me to throw some lime on the spill to clean it up... is this the right way of doing this? Is there a better way? Where can I buy lime if I need to do this?

Thanks in advance - chad
