For home use, store caustic soda safely by keeping it in its original sealed container inside a locked cabinet or storage area. The location should be cool, dry, and well-ventilated, completely out of reach of children and pets. Never store near food items, acids, household cleaners containing acids (such as toilet bowl cleaners or vinegar-based products), or aluminum cookware and containers. Always wear gloves and eye protection when handling, even in small quantities.
