If your stock has an oil finish, rub it down with lindseed oil. If your stock is a hard finish and the mildew is under the finish you'll have to remove the finish clean the mildew and refinish the stock.
First off shame on you for mistreating your guns you should never let them et that way. You could use simple green cut with water to take it off and not harm the finish.
well the other day has been the 1st time in a few years that i have been able to get to the back of the garage to open the safe. so much crap packed into it. made people get their crap out, i wasn't paid for storaing their crap.
1st of i was surprised i still remembered the S&G's tumbler combination, 2nd surprise was there was not one speck of rust on anything, the 3rd surprise was the mildew, minmal but still shouldn't have been there.
after cleaning etc, is there an anti-mildew treatment for them?

Ugh... don't let WD40 get on your wood, it is a penetrant and will seep into every crack and crevice and will rot your wood. Some good old fashioned lemon oil works fine, or linseed oil, just keep stuff like WD40 and Kroil away from your stocks and make sure your gun is completely rid of the stuff before you put it back together.

If it's on the guns, is it on the walls of the safe? With white vinegar in a spray bottle, spray down the insides of the safe, allow to dry then vacuum. 50% water/Hydrogen peroxide kills mold and mildew also. Once the guns are dry oil them down. If you don't shoot them much, coat them with petroleum jelly.
Bleach and water mixture on a rag and wipe it down. This happened to me when I came home from a 2 year deployment. But it was only on two of my CMP garand stocks and nothing else.
The bleach kills the mold and didn't harm the stock. But I am going to refinish them anyway and seal them with clear coat to prevent it in the future.
