The JPL three-level clean plan
Jewellery
Necklaces, rings, bracelets etc.

optional watch stand to hold the stones out of the water. If in doubt
please refer to our website: www.jpl.uk.com for further details.
Watches and glasses / sunglasses
Waterproof wristwatches, watch chains,
glasses, sunglasses etc.
Toiletry items
Electric toothbrush heads, electric shaver heads,
razor blades, combs, toothbrushes, dentures etc.
Ensure that all items are waterproof and non-porous.
Officeequipment
Printer heads, printer cartridges, fountain pen
nibs, wax or rubber stamps etc.
Tableware / cutlery
Wood or bone handled tableware / cutlery
should not be immersed. Only all-metal or plastic
tableware should be cleaned.
Metal items (some metals need enhanced
cleaning - see page 9)
Bearings, gears, valves, machine nozzles, small metal parts, old
coins, metal badges, gun cartridges, carburettors, etc. For best
results use Sea Clean or Metal Gleam concentrates as directed.
Watches should be fully waterproof (30m or more). For watches that are
not waterproof, the optional Watch Stand can be used. The coating on
some spectacle lenses can exhibit hairline cracking during ultrasonic cleaning.
If in doubt check with your optician before cleaning such items.
