Do restaurants use acidified pesto? Do pizza restaurants usually make their own pesto or use commercial acidified pesto? Found pesto squished between plates this morning (about 11 hours old) and concerned about a low-acid situation and how to clean it up safely. Or this this a non-issue even if not acidified?
first question: it depends on the pizza restaurant, smaller pizzeria might do the pesto in house, bigger pizza chains will use commercial pesto.

second question: in the case of washing, normal (very hot water and soap) washing procedure will clean up everything.
