There is no strict limit to how much vinegar you can put in a refrigerator, but there are a few considerations to keep in mind:
Avoid excessive spills: If you're using vinegar for cleaning purposes or storing it in large quantities, be careful not to spill it inside the refrigerator. Vinegar has a strong odor, and if spilled, it can permeate the fridge and affect the flavors of your other food items.
Store in sealed containers: If you are storing a significant amount of vinegar in the refrigerator, make sure it's in a tightly sealed container to prevent leaks or spills.
Organize space: Ensure that the containers of vinegar do not take up excessive space in the fridge, as it might hinder proper airflow and cooling.
Check expiration dates: Vinegar has a long shelf life, but it can degrade over time. If you have a large quantity of vinegar, make sure to check the expiration date to ensure it remains safe and effective to use.
Consider alternative storage: If you find that storing a large amount of vinegar in the refrigerator is impractical, you can store it in a cool, dark pantry or cupboard, as long as it is away from direct sunlight and sources of heat.
Remember that vinegar is an acidic liquid, and while it is safe for consumption, it's essential to use it wisely and in appropriate amounts. If you're unsure about the storage of a particular type of vinegar, check the manufacturer's guidelines or recommendations.
