Bluing is an oxidation process, as is rusting. It is not uncommon for the first several cleanings to have a brownish residue appear on your cleaning cloth. We offer a number of products and cleaning kits to care and maintain your firearm. If this residue persists for a long period of time or the problem worsens, then we would recommend that the firearm be evaluated by one of our Remington Authorized Repair Centers.
Always be sure to contact us first at 1-800-243-9700 before sending any firearm in for repair or service.
