If you have pets then you should have the BISSELL PET STAIN & ODOR PRE-TREATER SPRAY on hand for those occasional accidents. Even though my Shiba just turned 2-years old and she's potty trained, she'll still has accidents. The other day she ate something and threw up a little and so I used the BISSELL PET PRE-TREATER to spray the area, after wiping up the mess.
