Stripping silver plating can restore the shine of vintage jewelry or flatware and recover precious metal. Because the process uses strong acids, it must be carried out with full safety precautions and a clear step‑by‑step plan.

Step 1: Prepare Your Safety Gear

Wear the following protective equipment before you begin:

• Full‑coverage safety goggles or a face shield
• Heavy‑duty gloves (e.g., nitrile or chemical‑resistant) and a waterproof apron
• Long sleeves or a rain coat to shield arms and torso from splashes
• Ventilation: a well‑ventilated workspace or a fume hood that vents fumes outside.

Step 2: Mix the Acid Solution

In a porcelain or stoneware container, combine:

• 3 parts concentrated sulfuric acid (H₂SO₄)
• 1 part concentrated nitric acid (HNO₃)

Use a graduated measuring cylinder to keep the ratio accurate. Handle the acids with care, adding acid to water, never the reverse.

Step 3: Create a Controlled Heat Bath

Place the acid container inside a larger pot of water to form a water bath. Heat the bath with a burner until the acid solution reaches approximately 176 °F (80 °C). Monitor the temperature with a reliable thermometer.

Step 4: Submerge the Item

Wrap a piece of clean copper wire around the object to be desilvered. Suspend the object by the wire so it is fully submerged in the acid solution. Allow the plating to dissolve for a few seconds—typically 5–10 s, depending on the thickness.

Step 5: Rinse and Dry

Carefully remove the item and rinse it thoroughly with tap water at room temperature. After rinsing, roll the object in clean sawdust or a dry, lint‑free cloth to absorb excess moisture and aid drying.

Things You’ll Need

• Safety goggles or face shield
• Heavy‑duty gloves and waterproof apron
• Permeable rain coat or long sleeves
• Concentrated sulfuric acid
• Concentrated nitric acid
• Porcelain or stoneware container
• Large pot for water bath
• Heat source (burner or hot plate)
• Thermometer
• Copper wire
• Sawdust or lint‑free cloth for drying

Critical Safety Warning

Mixing sulfuric and nitric acids and heating them creates hazardous fumes and can cause severe burns. Ensure you work in a well‑ventilated area, keep all safety gear on, and never touch the acids with bare skin. If you are unsure about any step, consult a professional chemist or hazardous‑materials specialist.
