Use a Barrel with internal vanes for coin cleaning.
The tumbler runs to it's highest efficiency when the portions of compound and items to be cleaned is correctly ballanced with a maximum of 30% of the barrel volume.
Altering the volume of water will vary the finish of the coins with more water giving a gentler cleaning action.
Keep your coin types separate for cleaning eg, modern Decimal Half pence, 1p, 2p in one batch and the 5p , 10p, 20p, 50p. in a separate batch to avoid discolouration.
Don’t put coins of any value in a tumbler.
Using Steel medium, liquid soap and water, modern decimal coinage found on the beach should be clean enough to spend after a One hour cleaning cycle. (Two hours for heavier encrustation and discolouration ).
