Hello Guido I have been using an ultrasonic cleaner to clean slides. I remove the film from the mount. Kodak recommends adding a teaspoon of ammonia to a cup of denatured alcohol. It works very well. It also removes the protective lacquer found on pre-1957 Kodachrome. Two minute maximum time. More info in the 1971 Kodak publication "Kodak Color Films"
I have found that film cleaners that are applied with a tissue will result in many tiny scratches. My air compressor is a medical unit for breathing, i got it at a used goods store. Because it is medical, the pistons are oil-free.
