that is usually only a temporary fix. They need to be removed and taken to a stealers$it with a proper maching to bake them out, de-ash them and flow test them. Using only a blow-gun does not do much. Typically, it costs a few hundred bucks of you remove them yourself. Be sure to take pictures of their faces if you remove them and post the pics here for some evaluation on what the buildup might be.
