Question: I cleaned my Wheel in a mixture of bicarbonate soda and hot water and then was worried that it might have a detrimental effect on the programming of the Wheel.

Answer: The best answer here is to use it and see if it still works! You can clean your Wheel with anything you want. It will not change the programming. Warning! If you use a brush make it the softest one you can find. Silver is very soft and easily scratched. If it gets scratched it will dull. The only real treatment for a scratched and dulled silver Wheel is to have a jeweller buff it. Warning! Do not place your Wheel in an Ultrasonic jewellery cleaner as this will damage the emerald!
