Hopefully I loaded a page from Cleanwiki.com that shows how to deal with BBQ sauce. First RInse out the Oxy product with tap (not hot) water. Hopefully the oxy product has not damaged the carpet or removed any color.
I currently have those pages for over 40 stains. I add one when ever I have a chance. So another appears every few weeks. Get to them by going to www.cleanwiki.com. Then click on "Technical Resources" at the very top left of center. It will open a menu fo choices that includes free manuals, PowerPoints, Magazine articles, catalogs and so forth. The stain information is under Technical bulletins or something similar.
