So i took my other sks apart to get the chosmoline off it. i dunked everything metal into a tub of kerosene and put it outside to avoid the smell indoors. Problem is it rained over night, and i think some of the water got in because when i took the parts out the chosmoline was off but now there were rust spots on most of the parts. What should i use to get the rust off ? did i mess up the rifle should i scrap the whole thing now or what ?
