Take them to a good photo lab and ask their opinion. (Call a local pro and ask them to recommend someone) DO NOT wet the slide!
The mold in many cases feeds on the old film emulsion and when you clean the mold away the image is gone too. There is a new type of scanning software built in to some high end digital labs that may digitally "erase" most of the mold and scratches, as well as color correct the images too. You can have a CD made from the retouched images and/or have them printed. Ask your lab about their "digital ice" services
About the only thing that is safe is distilled water and a lint free fabric since the slide was developed in a water-based formula. When removing mold, you have to move quickly so as not to damage the softened emulsion. I would only apply a 'cleaning' chemical as a last resort.
