I have had my PA4x 76 key for 5 years and notice my white keys are not bright and white. I compare them to the lowest left hand key which is still bright and white. Any ideas how I can remove the grime? Regards, Rosco

I always clean my keys regularly with a dry microfiber , so fortunately don't have that problem. You could try that for a few weeks and see if removes the grime over time.
The other option which is often recommended for plastic (please google it and form your own opinion!) is a mix of water and white vinegar. Would try it on one key and check result.
