I ate comet cleanser now every time i eat my mouth hurts and burns things that arent even spicy such as fried fish chicken tenders bbq sauce pickles?

If you did this recently, it may take some time for your mouth to fully heal and for everything to return to normal. In the meantime, eating bland foods would probably be the most prudent thing to do. If this happened years ago, you may want to see a doctor, perhaps ENT or GI, to see if anything can be done to rectify the situation. Avoiding eating non-food items is crucial to prevent more damage

Comet cleaner can be a moderate irritant to the mouth and other mucus membranes, particularly if there is bleach in the mixture. If you are having irritation from it, you should call poison control or see your doctor ASAP. Good luck.
