“This comes re-labelled by Bevilles with the instructions "use as directed on your Beville's ultrasonic cleaner". I don't have one, I have another branded cleaner that I've had for years. When I tried to remove the label, it took off the original label information too, so it was useless. I'm not going to risk my jewellery using a strong cleaner that won't tell me the concentration or amount to use.”
