Just to add to what Prue advises. If you look at the slide/negative obliquely against the light you will see a definite difference between the emulsion side and the celluloid backing. The former will have a pattern which replicates the image.
There's always a chance you could damage the image by using any wet process but sometimes you may find something which would look better damaged than grubby.
Whilst water is an option - water was used in processing the film in the first place - and you used to be able to buy special film cleaner - the first thing I would turn to is methylated spirits. It's quite a good cleaning agent and it drys quickly.
Having processed many films over the years, the main problem a photographer experiences is the film gathering dust whilst it drys. It's necessary to hang it up in a dust free room and the emulsion is most easily damaged (eg fingerprints) whilst it's wet. One trick I learned was to use meths. for the final rinse (1) because it dissipates most of the water use to wash the film and (2) the film drys within minutes.
Using meths. to clean the emulsion side should minimise any softening of the emulsion.
