Good morning everyone, I'm hoping for some advice and help please on the new microplating machine I've bought from Cookson. It's the Balco make, 999 AUV. I also bought the rhodium ready mix 998 141R.

I have followed all instructions included with the machine, cleaned the rings well in a clean ultrasonic and then the cleaning salt bath within the machine. The reaction seems to be taking place in both the cleaning salt bath and the rhodium bath but when I take the rings out after the suggested time, they still appear to have a yellow tinge...

Can anyone help please?

Many thanks!
