Steam Irons

Most steam irons contain a protective coating inside the water chamber, but the coating isn’t meant to stand up against vinegar, so you should avoid adding vinegar to the tank. The acid can eat away at the lining and the metal parts. Check your iron’s instruction manual to find out specific cleaning instructions, or if your iron has a self-cleaning function, the only thing you should need to add to the tank is water to get the job done.

Pet Accidents

While vinegar is an excellent deodorizer and can effectively tackle all sorts of odors, it should not be used to clean up pet messes. Vinegar can remove the odors that people smell, pets will still be able to smell them and will more than likely revisit the area to mark the spot again.
