Welcome aboard Rbeukema.I'm that newbie that was mentioned above. I don't understand why you would clean/tumble (assuming similar to rock tumbling) an antique bottle. What draws me to them is the beautiful antique patina on the bottles. Isn't the value diminished by cleaning them up?
Some nice bottles you have there.
I would guess its your personal view of how you like your bottles to look.
I have always liked my bottles stain free but until I built a tumbler I couldn't get them that way. I believe they are worth more sparkling clean but that's just me.
Either way welcome. Roy
