Don a pair of sturdy acid-resistant gloves, goggles and a face mask. Cover all the skin on your arms with a long-sleeved shirt. Take every precaution you can to protect your eyes, lungs and skin from the stripping chemicals.

Fill a 1.5 gallon ceramic bucket with one gallon of water and the manufacturer recommended amount of circuit board stripping powder. Submerge your circuit boards in the solution. Mix with a one-foot long glass wand and allow it to set for at least eight hours.

Lift the circuit boards from the solution using metal salad tongs. Remember to wear your gloves. Don't touch the solution or reuse the tongs for food preparation. Shake the circuit boards over the ceramic container to remove any loose pieces of gold.

Place a metal coffee filter over a second 1.5 gallon ceramic dish. Slowly empty the contents of the first bucket into the second, allowing the liquid and gold to pass through the coffee filter. Lift the filter from the bucket once you finish.

Dump the contents of the coffee filter into a clean, white ceramic plate. Sift through the contents of the plate for gold scraps with the metal tweezers. Store the gold scraps in a clear glass jar so they remain safe.
