Almost every year, I will disconnect my audio components for cleaning. Many suggestions as to the liquid to be used for the job. Usually, I just use a lightly damped (with water) cloth to wipe them…that’s it to it.
Few years ago, I was presented with CHISTO products/solutions which I found to be useful and effective. Given the delicate finishes on the FM ACOUSTICS component chassis, I tried the CHISTO’S SPRAY & WIPE…the shines came back!
It is easy to use…just spray and wipe.
