WD40 would lubricate the maggy and therefore keep it all nice and fast, the water is MUCH better than royal blood, its rapid (just bled mine iwth water from royal blood last night) but theres one downfall, it can make your calipers slow after about 5 months, but all you need to do then is bleed it was royal blood (or cooking oil [Maybe VERY VERY VERY slow]) and ide it for about 1 week, then re-bleed iwth water again :(
