Originally posted by Binocular Viewfinder Thank You biz-engineer, I disinfected my PK to Fuji X lens adapter with 91% Isopropyl when I recieved it a few days ago. Those of you that don't feel the need to take any precautions concerning this matter, Do Not, those that do, Do...
Warning - Using alcohol on the camera body is ill advised according to Pentax. From page 128 of my K-1 operating manual, "Do not clean the camera with organic solvents such as thinner, alcohol, and benzine."
This makes sense because solvents can attack/degrade certain types of rubber, potentially risking damage to the excellent weather proofing seals in Pentax cameras.
A better idea, but one requiring much more patience, would be to put your camera or lens in sunlight for a number of days (rotating it to expose all surfaces for extended periods), allowing natural UV radiation do it's magic as a natural disinfectant.
