Everyone should have WD 40 around the house and it makes a good safe cleaner for these areas. It has some lubricating abilities and will not harm and materials. The carrier has cleaning abilities (It was designed to clean rocket parts) and with protection agents it prevents moisture from forming on parts.
After cleaning the bore I place the muzzle down and wash the bolt lug and the chamber area with WD 40, let it drain while i am washing the bolt off with it. them wipe everything off and swab the chamber with a cotton swab and a few patches and then apply a light coating of oil to everything that the solvent may have came in contact with.
There are other cleaners, but they may have products in them that can/may harm some materials.
