Standard cross infection protocols call for through cleaning of equipment between patients.

I have noticed that my curing lights and operating lights are starting to experience crazing and cracking of plastic components, thereby making for uncleanable fissures. These items are less than a year old so heaven knows what they will look like in the future.

I wonder is it the alcohol based disinfectant sprays, or careless use of orange solvent that has done this damage, or is it something else? Perhaps fellow readers should do an audit of their plastic items to spot this sort of problem?
