Is There a fix for CD Pin-holes (CD Rot)

I have several early CD's (1984 to 86) with pinholes and some pitting on the label side. Mostly German pressings, many made by PDO. They all have played fine until I bought some early discs with the silver mould area. Pinholes in the center ring cause disks to spin loudly in the transport and sometimes cause read errors.

I've read about the deterioration of CD's; haven't seen any with discolouration (CD rot). Is there anyway to preserve the many CD's in my collection so that discs will continue to play?
And please don't suggest that I give up and burn the discs to a server. I like the physical medium and many of my discs are collectables.
