Chem-Dry removed all evidence of peanut butter for $45--a bargain to this overwhelmed mama!
I have cleaned these chairs myself by soaking the cushion covers in the bathtub.
As Carrien commented, a degreaser is essential for peanut butter cleanup: Dawn detergent works well, as would her Simply Orange suggestion.
I called the pros because I didn't want to force the peanutty oils into the arms and back upholstery without extraction.
How many of you have found a home carpet/upholstery cleaner a frugal investment? Any advice for buying one?
