How to remove clearcoat on copper pots & pans

Q. Hi, I just bought a set of pots with copper bottoms at a liquidation sale and just noticed that I need to remove the lacquer coating before using. I found your question on the internet. I was wondering what method you used and did it work. Thank you.

A. Try oven cleaner [affil link on Ebay & Amazon] or Marlena Baker's solution...
acetone [affil link on Ebay & Amazon] mixed with ammonia [affil link on Ebay & Amazon] (25% - 1 part acetone / 3 parts ammonia) can be used too. Hope it helps and good luck.

Q. I have obtained two pieces of copper(outside) over stainless steel cookware. These are coated with ?. I tried to remove it with nail polish remover and elbow grease, but that's not working. What will remove this coating?

It is a clear coating to prevent tarnish. I've received emails that mild detergent will remove this coating, ha, they're wrong.

The skillet is a piece of Revere ware produced in the late 1970's. It is stainless steel covered with copper on the outside. To protect and keep it from tarnishing the company used ? to coat it. So this coating has been on this piece of cookware for over 20 years. I do not want to display this but use it. So I need to remove the coating. I have two other pieces like this that I bought in the 70's but can't remember what I used on the coating. Hope this helps.

A. How do you know that the coating is still there? I also have a set of Revereware of that vintage. After washing it, I just used it for cooking. Any remaining coating was probably incinerated! If you think the coating is still there because there are darker spots where the copper oxidized over the years (pin holes in the protective layer) and brighter spots where the coating protected it, just remember that the areas that were protected aren't going to oxidize immediately. It will look measled until the protected spots oxidize to match the areas that were unprotected. Also, Revere makes a Revere copper cleaner . You could try using that. It has a slight abrasive, but not enough to scratch. Takes the oxidation off the copper parts so you could make it all look the same.

Good luck,

A. This is from Revere's website taken directly from the warranty. Hope it helps...

"To remove protective coating:

• In pot large enough to immerse at least half of this item, combine 1 tblsp. baking soda [affil link] to each quart of water used.
• Boil solution. Submerse item in boiling solution and boil for 20-30 minutes. The coating will soften & begin to peel.
• Remove from solution and wash item in warm, soapy water, scrubbing with a Nylon scrubber to remove softened coating. DO NOT use steel wool.
• Finally, clean with copper cleaner (available at supermarkets) and a soft sponge."

A. I have had a set of the all-copper-clad-stainless-lined cookware, since the '70's, as well as many import pieces. In the beginning, we were told to NOT cook with it till the lacquer coating was removed. Cooking would harden the coating and super adhere it in spots - true. To remove that, we boiled the pot in vinegar [affil links to item on Ebay & on Amazon] -awkward! Recently, polishing the ENTIRE collection, with desperate attitude of the old & cranky, I gave some a shot with spray oven cleaner [affil link on Ebay & Amazon]. BONANZA! Even 30 yr old lacquer moved! Does NOT hurt the copper! Followed up with a Paste Cleaner (not powder), polishing is fun again!

A. Boiling does work well. If the pot is large, you might have trouble finding a large pot in which to boil it. The finish is a kind of varnish. You can also buy a can of acetone [affil link on Ebay & Amazon]. Take the pot outside and use a rag to apply the acetone. The acetone softens the varnish. Then you can go inside and use Barkeepers Friend [affil link] and a pad to clean it up under warm water. The acetone is MUCH quicker than boiling and MUCH easier. Good luck.

A. Hi, This letter and several others on our site reveal that the coating is not so easily removed from 30 year old cookware. Whether that's because the formulation was different 30 years ago, or because the coating has cured for 30 years, the fact is that a more aggressive removal method may be needed on the old stuff.

Q. I have some unused copper pieces, still finished with a protective surface. I understand that this should be removed before use . I have a gas stove, so the intense heat would burn the finish to the copper.

A. The tip to use oven cleaner [affil link on Ebay & Amazon]! I just added a piece to my set of Revere Copper from the '70s and the new piece had the coating. It came off perfectly! Back in the 70's I was boiling my pans in baking soda, and this was so much easier. Absolutely no damage to the copper! Thanks!

Q. I just bought a copper pan. The website says it is treated with lacquer and needs to be wiped with acetone [affil link on Ebay & Amazon] before first use.

I have done that - using nailpolish remover - however there was not really much of a reaction - I was expecting some stickiness or a layer of something to be removed. I want to be sure that if there is something there that I remove it properly so I don't ruin the copper when I use it.

So, my question, how can I tell if the lacquer is removed, or for that matter, even there in the first place?

Hi, Liza

This may not be the right answer for you or Ronna, but it may help somebody. Copper is electrically conductive and lacquer is not; so, you can touch the probes of an inexpensive VOM Multimeter [affil link] at a few different spots to determine if the lacquer has been removed. Good luck.

A. I used Brake Parts Cleaner and it was instant. Just brush off the coating with a scrub brush. Do it outside and wear gloves.

Q. Someone spayed a copper display item with a can of krylon matte clear sealer to try to protect it. But now it is dark and tarnished. What can I use to get rid of this sprayed-on sealer so that I can RE-POLISH the copper?

A. Hi Beth. Try lacquer thinner [affil link] first. If that doesn't do it, methylene chloride will if you can still find any (it's very toxic, requiring goggles [affil links to item on Ebay & on Amazon] & rubber gloves [affil links to item on Ebay & on Amazon] as a minimum and working outside from upwind). If you can't find a stripper with methylene chloride anymore, or don't want to use it, read on for some other possibilities.

Luck & Regards,

A. Try 3 parts acetone [affil link on Ebay & Amazon] and 1 part ammonia [affil link on Ebay & Amazon] (25%) mixture. Use safety goggles and rubber gloves! Bad smelling but very effective.

Hope it helps and good luck!
