Balco Rhodium Plater

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!

How hot is the water in the machine ? It needs to be room temp apparently from memory those machines are set at 40 deg C. but that could of changed this could possibly have an effect

Go back to Cookson, and they will ask their parent company. I suspect that the answer will be to extend, or even double the plating time. Dennis.
