Just use soap & water before your Hoppe's or whatever you usually use. The problems will only crop up if you neglect the areas where the corrosive salts from the priming may collect: op rod, op rod area / valve near front sight; inside of action, etc. Just literally "wash" the rifle with soap- Murphy's Oil is good, but others use "Mr. Clean" or just regular soap - then clean as usual. If your worried you haven't dried it use a hair dryer. Hoppe's or conventional solvents may not dissolve the salts. Those 2-chambered cleaning bottles that used to come with all the Russian Mosin Nagant rifles had one chamber for soapy water, one for oil - for a reason!!
