What’s Causing White Chalky Residue On My Stainless Steel Cookware?

It’s the time of year when temperatures drop and our thirst for hot beverages and soups goes up!  It's also the season where we notice more white residues on pots that are used to boil water.  While the idea of residues on things used to prepare food in can cause anxiety... they are usually completely harmless!

What Is The White Chalky Residue On Cookware?

Mineral Buildup On Stainless Steel

Hard Water Mineral Buildup

In nearly all cases, the white residue is from calcium and magnesium-containing minerals that are found in tap water.  The minerals build up on pans when water boils, evaporates, and leaves them behind.  If the mineral deposits have "baked on," a normal dishwasher cycle typically won't be enough to remove them.  In fact, if you use a natural dish washing detergent, the residue can actually get worse!

How To Get Rid Of White Residues On Stainless Steel Cookware?

Even though hard water mineral build-ups on cookware are harmless, they are unsightly and some people want them gone.  Fortunately,  this is very easy to do!  Mix up a 3:1 solution of water and vinegar (any kind), put the solution in the affected pot or pan (make sure to completely submerge the mineral deposits), and turn heat it up on the stove.  Once the water starts to get near boiling, shut off the burner, and let the hot liquid dissolve the mineral buildup.  Sometimes it helps to give the solution a few swirls every once in a while.  Once the buildup has dissolved, dump out the vinegar solution, rinse the pot with cool water, and wipe the pot dry.  Easy peasy!
