I am usually careful and not that this is obvious but I dabbed a tiny bit of acetone on the gold contacts for cleaning on my new camera body and it faded the plastic. Good quality plastic won't do that so easily but on these new DSLR bodies forget it!
The cheap quality of everything today! |

Acetone is a strong organic solvent which dissolve most plastics.

you should use multi oil (not WD40) for cleaning electrical contacts or maybe just simple alcohol
I use alcohol every time I get a new lens, clean them from top to bottom without the glass of course  |

About the strongest solvent I'll use on a modern plastic camera is alcohol. It will usually handle most cleaning chores, I've found.

Well I suppose you have a point for large plastic DSLRs, maybe I should have said:- "it's excellent for older film cameras".

Is the coating on the outside or the inside of the glass? |

Outside, don't even think of trying acetone on glass, it would definitely ruin the coating. Make sure to get the one with lower water content, as the 70% iPrOH solution often leave behind water streak when evaporated. Alternatively, I found Zeiss's lens cleaning solution to be good on glass. |

Caution with lenses older than 1970 or so, some lens coatings are easily damaged by solvents, some even have water-soluble coatings(!). Older lens cements can dissolve in solvents resulting in separated elements. Florite elements are particularly fragile, seek more information before attempting to clean a florite element! |
