Hi am after recommendations for cleaning the inside surface of a C11 corrector plate. U tube abounds with information , removal of corrector plate is covered in several videos but cleaning is so varied . In some cases is worrying by its technique , for example lens wipes . I’m interested in some tips and recommendations from those that have done it. I’m thinking of cleaning with a few drops of dish washing liquid in water as with a mirror except keeping the secondary dry or using bintel fluid as on the front.However the first method would be more gentle and maybe more effective?
