For disinfection of smaller equipment with electric/electronic components we recommend using Mycoplasma Off Wipes. Especially for devices with sensitive elements like microscopes, the wipes allow a more controlled/safe treatment than the spray and are a much better choice to clean the device thoroughly (wheels, switches etc.). However, you could try to moisten a clean paper towel with Mycoplasma Off and wipe the microscope with it. Cleaning of delicate components like objectives/lenses/filters with Mycoplasma Off is definitely not recommended. We also suggest spot testing to check for possible discoloration.
