cleaning pennies

[underdogger]

I have double spin rock tumbler With one having red gravel for pennies only the other blue rock . do not try with any silver !!!!! clad only Take hand full of pennies place in red gravel Add a splash of amonia with toilet bowl cleaner no more than a quick squirt. tumble for 15 min only. Any longer preasure will build up and make a hell of a mess. Be extra careful when re opening and now you have pennies that the bank will accept. cheers rob.
