So I've been making homemade sauces for a couple of years and I've tried to follow good sanitation processes. My question is if your sauce is going to be around 3.5 ph level or below why do you need to sanitize everything (cutting board, knives etc...)? I guess I can understand sanitizing the woozy bottles although again if the ph level is low enough I thought the nasties couldn't survive anyway. The reason I ask is when I make a sauce I cook it and put it in a mason jar overnight so I can try it the next day and tweak if necessary. That means having to sanitize everything twice which is more time and sanitizer which is not a big deal just an annoyance. I have an extra refrigerator so I store all my sauces in the fridge for long term storage so technically I guess it doesn't have to be shelf stable even though my ph is is low enough to be. So I guess to sum up, why do you need to sanitize if your sauce has a low ph?
