What Not To Do When Cleaning Lacquered Fixtures

While cleaning lacquered fixtures, avoid products and methods that can damage or dissolve the lacquer. Steer clear of the following, which can strip away the lacquer coating:

• Abrasive pads or cleaners
• Harsh all-purpose cleaners
• Products containing ammonia or alcohol

How To Clean Uncoated Brass and Copper

Uncoated brass and copper fixtures can develop a beautiful patina over time, but they may also tarnish or become unsightly. Cleaning these materials requires a gentler approach to preserve their natural beauty. Below are effective methods using common household ingredients for cleaning uncoated brass and copper fixtures.

Lemon Juice and Salt

For small tarnished spots on brass or copper fixtures, rub lemon juice on the affected areas. For heavier tarnish, create a paste using:

• Lemon juice
• Salt
• Cornstarch

Apply this paste to the tarnished areas, let it sit for a few minutes, then rinse with mild soap and water. This method is particularly effective for brass fixtures.

Baking Soda

Baking soda is an excellent, non-abrasive cleaner for copper fixtures. It gently lifts tarnish without scratching the delicate copper surface. Here’s how to use this method:

1. Mix baking soda with lemon juice to form a paste.
2. Apply the paste to the tarnished areas of the copper fixture.
3. Let it sit for a few minutes.
4. Rinse thoroughly with clean water.

Olive Oil

For an extra layer of protection, apply a small amount of olive oil after removing tarnish from brass or copper fixtures. This method preserves the shine and helps prevent future tarnishing. Here’s a simple method:

1. Use a soft cloth to apply a thin layer of olive oil to the clean fixture.
2. Polish gently in circular motions.
3. Buff with a dry cloth for a subtle sheen.

How Do You Remove Oxidation from Outdoor Light Fixtures?

Oxidation can make metal fixtures look dull and aged. To remove oxidation and restore shine to outdoor fixtures, follow this guide:

3. Scrub gently with a soft-bristled brush.
4. Rinse with clean water and dry thoroughly.
