Neoprene gloves work great, and they're cheap. If you have an industrial supply house near you, such as W.W. Grainger, you should be able to pick up a pair for less than 10 bucks.
Sorry, Mr. S, I didn't notice that you are in Spain! I doubt there's a Grainger warehouse near you! Anyway, industrial neoprene gloves do work well (I say, while slapping myself upside the head).
