Default Removing zinc plating from a water heater element

Over a year ago I bought the parts to build two heat sticks, and I finally got around to putting them together. I bought two of these low watt density 1500W elements.

I used them to brew, and they worked beautifully! After the brew, however, I noticed that the elements were now a dull, darker grey. I also went back and looked at the link that I posted above, and saw that they are zinc plated.



I figured that it's probably not good to have that happen, so I found a post on another beverage hobbyist forum explaining how to remove the zinc.

An overnight soak in a citric acid solution, and a couple minutes with a green scrubby, and the elements are down to the copper.



It's all shiny copper, the darkness, especially near the base, is just shadow. I didn't have time to set up proper lighting this morning.

Nice. Would you elaborate on the "citric acid solution"?

I dissolved somewhere between 1 and 2 oz of citric acid powder in somewhere between 1.5 and 2 quarts of hot water. Not too scientific, I'm sorry.

Sorry, I'm thick. What is citric acid powder? Do I need to visit Hogwarts to get it?

It's powdered Citric Acid. As opposed to liquid. White. Fluffy. Looks like talcum. derived from the acid in citrus.



HBS's have it.

Gila is right. I had a 2 oz bottle that I had bought at my LHBS for a buck and change.

You could probably use diluted lemon juice concentrate from the grocery store.

Great! I have a lemon tree that is currently full of useless lemons. [reminds me of an old Peter Paul & Mary tune]

Wal-Mart has it, a lot of grocery stores have it. It is used when canning fruit. If you dip fruit in a mild citric acid solution, the fruit won't turn brown.

Yeah. It is common. Except in my Walmart.
