First of all, I try to remove dust and tiny particles with a strong jet of air from a rubber bulb (the bulb has to be free of powder). Also, the simple wiping with soft and repeatedly washed cotton T-shirt will do no harm to the front lens, and after that any tiny leavings are easy to blow out.
And when the front element is very dirty and blowing or wiping doesnt work, I figured, that good result gives the very gentle wiping the front lens with a soft sponge dampened with diluted, not aggressive detergent, then sponge off a possible foam with a damp cloth, aid then wipe the lens dry. Of course, be careful that no water gets inside, the sponge should be damp but not dripping.
