Scrubbing Away Peanuts: Good news for the peanut sensitive. Ordinary household soaps get rid of the allergen, for the most part:

In the study, researchers applied a teaspoon of peanut butter to the hands of 19 allergy-free volunteers. Hand wipes, liquid soap, bar soap, plain water and a hand sanitizer were tested, with only the sanitizer failing to remove the allergen.

Researchers also compared the performance of plain water, dishwashing liquid, Formula 409 cleaner, Lysol sanitizing wipes and Target-brand household cleaner with bleach in removing peanut butter from a clean table. Only dishwashing liquid failed.

'It's possible that dish soap creates a film over eating surfaces, making it difficult to clean underneath,' Wood said. 'But our results suggest that even if a child licked the table vigorously after it had been cleaned with dish soap, he probably still couldn't get enough allergen to cause a reaction.'
