i was cooking some dessert today which contains milk as a primary ingredient. While cooking I started to notice that powder ingredients weren't dissolving in the milk. After a while under heat they dissolved, but I noticed what looked like soap bubbles. We usually use Fairy Soap for washing kitchen tools and Clorox. Now I'm concerned if we can eat what I've made or if it poisoned. The soap came out of the tool I was using to cook the dessert.
Most pure soap is safe to eat in small amounts, but the food won't taste great. Fairy Soap, from some brief research, is safe to ingest in small quantities, but I wouldn't recommend it. Bleach in very small and diluted concentrations won't hurt you, but it's very toxic if larger quantities are ingested, particularly undiluted. It is a very strong base. If you think you put (any) bleach in your food I would throw it away. If you think you put soap in your food, I'd also throw it away. The maxim I live by is: "When in doubt, throw it out."
By the time you could get anywhere near enough soap or bleach in food to be vaguely dangerous, it would be so strong you wouldn't be able to eat a second mouthful.
You can try these tests:-
Wash a spoon in your regular washing-up bowl before anything else, so it's as clean as clean can be. Don't rinse, just shake it once. Lick it. How strong did that taste? Imagine doing the same with a pan, but afterwards half filling it with water or food as you're cooking it. That concentration would then be further diluted by a thousand-fold.
Touch your finger lightly to the open top of the Washing-up liquid bottle. Taste.
Now, that still won't do you any harm, but would you imagine being able to eat anything with that kind of soap concentration in it?
Don't repeat the tests for bleach. The smell alone is enough to warn you not to go anywhere near any concentration high enough to be able to still smell it in food.
Note: soap is not the only substance that will form bubbles. Bubbles alone are zero indication of soap contamination.
