The only thing to use is a qtip and a little denatured alcohol.&nbsp; The act of mounting and removing the lens is enough to keep the contacts 'clean'. They are gold plated and very fragile. In you case I would call Canon.&nbsp;<SPAN>1 (800) 652-2666</SPAN></P> Thu, 05 May 2022 15:10:11 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Canon-M6-Mark-ii/m-p/371087#M87450 ebiggs1 2022-05-05T15:10:11Z
