If it really is silver brazing alloy, the steel it's stuck to would need to be heated to near dull red to get it to flow, at which point it can be mostly wire-brushed off or blown off with compressed air. You'll likely still have a thin coating that remains. Re-establishing the clearances by drilling out the alloy may be your best bet.
