What do you recommend me for cleaning the internals of the Milbro/Diana I am restoring. Can see lot of dirt and little bit of rust inside the cylinder and on the piston and spring.... The rifle has not been cared for for a number of years. How about soaking it in petrol and then wiping it dry...may be leave it out in the sun for sometime then to make sure all the petrol evaporates...? Or do you suggest something else....
Use RUST LEAK to remove rust and then polish the part with fine water paper!!
