@Bella Dea,
i just steam clean the carpet over and over and over and over.
(thi brings up the recent memory of the ******* IDIOTS AT MY GMAS HOUSE that let their dogs use their "old" room as the potty place, the floor was wood and when we pulled the carpet there was a black spot about 2 1/2 feet wide of rotten wood)
yeah, but anyway, steam clean it once, do it again right after, then i go back the next day after it dries and do it again.
and again
and again.
if its bad it prolly wont work.
;D
