Yes, a very common practice...
That's exactly what this guy did...
He just bought regular paint remover at the store, doesn't harm the glaze at all....
E ! Thanks !!!!! Now I will be spending every spare dollar on painted jugs , you just had to go and post this didn't ya ? by the time I find one I will have spent a $1.000 bucks Do you know how many painted/decorated jugs I have seen through the years and they are usually pretty cheap . I can't believe in all these years I have not thought of this !!!! definitely going to be a new area of collecting for me and if nothing else I will end up with one heck of a blank jug collection. Congrats !!!
