I am needing to remove corrosion from copper bowls

I am looking to remove corrosion from copper bowls. Do i need training for the vapor hood or media blaster cabinet? Or Is there a day this week i could get help?

My concern would be that these options would be too aggressive and remove too much material.

I’d look at chemical options or armstrong solutions like Bar Keepers friend.

I agree. Things like lemon juice or vinegar together with an abrasive like salt are often used for polishing copper cookware. Or lemon reacted with baking soda to make sodium citrate. Oxalic acid (“bar keepers friend” that Rich mentioned) is another option.

The thing in common is that people typically use weak organic acids to get rid of corrosion without removing the underlying copper. An added bonus is that these acids are safe to handle (and to eat in reasonable quantities).

If, after reading the advice above, you still want to use the vapor hone, you can do that. It does not require training. There are some signs on the cabinet that walk you through the steps to make sure it is set up properly. It’s quite simple.

The media blaster itself is shown here with the black hose. It has a simple trigger mechanism. There is a water hose inside (shown here with the blue coil and red nozzle). The water is used to rinse and also to rinse the cabinet per the instructions on the cabinet.

The vapor hone is NOT a parts cleaner (i.e., no greasy parts) but that doesn’t sound like it’s an issue in your case.

If you decide to use the vapor hone, I strongly recommend you wear gloves inside the gloves. At least one of the gloves leaks and it can be really nasty inside the glove.

I’ve cleaned copper with hot sauce. It works pretty good.

Vapor hone seems like it’d make quick work of that corrosion. I think as long as you’re careful with nozzle distance and don’t go at it too hard it’d be fine.

For a less aggressive but more time/labor intensive option, I’ve been really happy with Brasso as a polishing compound. It will take care of that corrosion but it’ll take time and effort.

That stuff is amazing. Removed so much corrosion from my sink when I bought my house. Sink was gross and now it shines!

Its the same stuff (oxalic acid) that’s in spinach (and kidney stones for the unlucky few) plus a bit of soap mixed in (SDS).

The vapor home really isn’t down. Idk who put up that sign, holes in a glove isn’t a reason to take down the machine…… that said, 2 pairs of gloves are on order

Vapor hone is going to leave a rough surface. I would try 30% cleaning vinegar and a purple scotch brite pad. Gray scotch brite will remove scratches left by the purple pad.
