some keys don't work, dirty circuit.

My video entryphone comptel MT-VCT-01 had some keys that don't work. So I disassembled it and got to the circuit of the keys. I made this another time before, but only the rubber keys were dirty. Now also the circuit is dirty. So my question is, how I clean it?? And can I clean the rubber keys with water if then I'll dry it perfectly?

thanks you!!!


(I'm italian and I'm 16. So sorry if I made same mistakes)

Giovanni Riva, you can clean all those items with + 90% isopropyl alcohol. After that just let them air dry. Hope this helps, good luck.
