How to Clean Lacquered Copper

Copper, with its rich hues ranging from rosy pink to deep brown, is a timeless metal often used in jewelry, home decor, and kitchenware. When it comes to cleaning lacquered copper, understanding the protective finish is essential.

To preserve its shine, most copper items come with a protective lacquer coating that helps prevent tarnishing and oxidation. In many ways, a lacquer finish works like clear nail polish, forming a protective barrier against the elements and making cleaning easier.

Cleaning Lacquered Copper

When cleaning lacquered copper, it’s important to be gentle to avoid damaging the protective coating. Before you begin, if you’re not sure whether your copper is lacquered, check its appearance. If it looks dull or dirty but has no visible tarnish, it’s likely coated.

Avoid Harsh Scrubbing

First and foremost, avoid scrubbing or using abrasive cleaners, as these can damage the lacquer, leading to tarnishing underneath.

Use Mild Cleaning Solutions

Instead, it’s best to stick with warm water and mild soap for regular cleanings, as lacquered copper requires minimal maintenance and will remain shiny for years with just basic care.

Simple Cleaning Solution

Ingredients

• 2 cups warm water
• 2 tablespoons mild dishwashing detergent

Cleaning Process

• First, mix warm water and dishwashing detergent in a spray bottle.
• Next, spray the solution onto the copper surface.
• For heavily soiled areas, allow the solution to sit for a few minutes.
• Then, wipe the item with a soft cloth to remove dirt and grime.
• After that, rinse with clean water and dry thoroughly with a soft cloth.

Tarnish on Lacquered Copper

However, if your lacquered copper is scratched or damaged, tarnish may form underneath. In these cases, you may need to remove the lacquer entirely to restore the original beauty of your copper piece. Additionally, older copper items may appear blotchy as the lacquer wears off, requiring removal and reapplication.

For this reason, keep lacquered copper away from heat and moisture — such as near stoves or in bathrooms — as these conditions can lead to tarnishing beneath the protective coating.

Lacquer Removal Solution

Ingredients

• 1 gallon of boiling water
• 1 cup of baking soda

Removal Process

• To begin, in a large pot, combine the boiling water and baking soda.
• Then, carefully lower the copper item into the solution using tongs.
• As the lacquer loosens, you’ll see it peel away or notice a white, filmy residue rise to the surface.
• After that, remove the item and polish it immediately to eliminate any leftover lacquer.

If necessary, repeat the process until all traces of lacquer are gone.

Dealing with Stubborn Lacquer

If the lacquer isn’t coming off easily, you can try using acetone (like nail polish remover) or lacquer thinner. Both are effective at breaking down tough coatings and can be found at most home improvement stores.

Finally, after the lacquer is removed, remember that your copper will behave like bare metal — it will tarnish over time. Therefore, regular polishing will help keep it looking shiny and beautiful. With a little care and consistency, your copper pieces can stay stunning for years to come.
