ya anything with more moisture will do the trick, i wouldn't use an apple cuz ur bud will stick to it...i would go more along the lines of bread or sumthing..take a crust of bread and throw it in there. should help alot. or get a moist paper towel and wrap ur buds in it and throw it in the mic that alwase works too. depends on if you want a quick fix or sumthing that'll take longer, but won't stink up u house.
