Hey guys trying to clean up my haul of files I scrubbed them in a sink with warm soapy water, then quickly dried in a preheated oven. (Don't tell my wife about the stove or her sink!! LOL) Then soaking them in white vinegar. Here is my question there is still some rust in places on them. Is that OK? Also can you put a fine oil on them like air power tool oil to keep them from rusting? Also, If the vinegar don't cut the mustard can you use Muriatic Acid watered down? I have used this on steel traps and it cleans them up slick. As always thank you for your help!!
