Hi Karen and thank you for your question. Here's an answer from David W. Hauswirth, M.D., Assistant Clinical Professor--Medicine and Pediatrics, Division of Pulmonary, Allergy, Critical Care and Sleep Medicine at The Ohio State University/Nationwide Children's Hospital:
Based on studies done looking specifically at peanut protein on tables and hands, hand wipes were better at removing the peanut protein. The antibacterial hand sanitizer used in these experiments did not completely remove all of the peanut protein on hands. Commercial wipes, liquid and bar soap all removed the peanut. Nothing, water only and hand sanitizer left a trace of peanut on hands. Hope this helps.
