I definetly would NOT recommend dunking eyepieces or using any type of compressed type air to clean your eyepieces!
Recipe for disaster IMOP
Any increase in pressure will drive any dust/particles/water in deeper to the seals causing grief in the long run.

A more carefull approach is highly recommended as others have stated.
Also you need to use white light source to look at the glass not red.
