Use a toothpick to gently scrape off the old foam from all areas that need replacement.

Dip the toothpick in 91% (or greater) isopropyl alcohol (IPA).

Use the damp toothpick to loosen and scrape away sticky residue.

Repeat the same cleaning process for mirror bumper, door hinge, and any other light seal sections needing replacement.

Be careful not to scratch any metal surfaces or let foam particles fall inside the camera.
