I remove mine, get them wet in the sink, place a drop of dish soap on the friction material of one pad, rub the two pads together to clean off the contaminates, rinse with water and only handle with a lint free towel, reinstall on the bike. This has worked for my noisy pads many times. If the pads have mineral oil or brake fluid on them, you should also thoroughly clean your rotors witch are likely also contaminated or your brakes make still make noise.
