I remember a workmate had one he used to brew his tea in and it was stained inside from constant use.
One of the lads cleaned it for him with sand till it was spotless. But the chap went mad and said the tea will
never taste the same.
I had to have my one pts last Sunday as he had a stroke. He was nearly 15 and a great little dog. I would have another one tomorrow.
Good luck with your searching.
