When your cleaning coins please read the following before watching the video…
| Surfaces may be wet cleaned if surface finishes are stable. Use a mild detergent and water. Follow with a rinsing wipe, using de-ionized or distilled water. |
| Dry Cleaning Objects… Objects may be dusted with soft bristle brushes if the surfaces are solid. Do not clean if finish materials (paints, decals labels, paint inlays, etc.) are flaking, peeling cracking, or sticky. Do not clean if the object has unstable areas. Ensure all parts are attached securely. Areas of corrosion may be removed if the underlying metal is sound. Active corrosion may be identified on copper, brass, and bronze as bright green to blue areas with loose materials and flaking. Black to brown corrosion materials on copper alloys are stable. Black to brown materials on silver are stable. Purplish to grey materials may be active corrosion. Be aware that silver-plated objects may have both copper and silver metals present. Silver-plated objects may show green copper corrosion products where the copper has been exposed. Polishing these objects may put them at risk. Corrosion on silver/brass/bronze may be removed with polishes, pointed applicator sticks, and mild abrasives. |
