2 ways to try,
easy way is get a tin of aerosol Brake Cleaner (e.g. Halfords typically £4-50 a tin) and just spray the caliper and pads to wash out the dust.
Better way is get a tin of Brake Cleaner and some Copper Grease, take the pads out, spray everything to clean the crud out, clean the backs of the pads taking care not to lose any shims that might be fitted. When clean, very lightly smear some copper grease on the backs of the pads and the shims, and reassemble.
