Will vinegar corrode copper?

Caring for copper: Why you should skip the vinegar

It is easy to assume that natural pantry staples like vinegar and lemon juice are the safest choices for cleaning metal around the house. However, when it comes to copper, these acidic cleaners can actually do more harm than good.

Applying vinegar or citrus juice to copper will quickly strip away any protective lacquer or applied finish, leaving the raw metal exposed and vulnerable. Over time, this constant chemical stripping dulls the natural luster and ruins the intended aesthetic of the piece.

This caution extends beyond simple kitchen wiping. If you own a copper bathtub, you should strictly avoid adding acidic bath additives—including certain bath and Epsom salts. These compounds react with the metal, leading to stubborn tarnishing and accelerated corrosion that mars the surface.

To keep copper looking its best, skip the harsh acids. Instead, stick to gentle care routines, such as washing with mild dish soap and warm water, and drying the surface thoroughly afterward to preserve its finish for years to come.
