In order to loosen rusty nuts, bolts and screws, use a product called PV Blaster and spray it on the object. Let PV Blaster sit on rusty nuts, bolts and screws for 10 minutes before removing them with help from an auto mechanic in this free video on car maintenance and repairs.
Hello, my name is Tom Brintzenhofe, certified master mechanic, from Reading, Pennsylvania. Today, we're going to talk about how to loosen rusty nuts, bolts, and screws. The best product out there on the market, in my opinion, is probably called PV Blaster. This stuff is phenomenal. If you ever have something that doesn't want to come out, the best thing to do with this, is spray it on, and let it sit for about ten minutes, and then work it back and forth, and it will come out fairly easy. Just spray it in on your rusty nuts, your rusty bolts, whatever. Let it sit for about ten minutes. When I come back to it, I've sprayed it earlier, so it should come out fairly easy now. Just get your socket and nut on it, and just work it back and forth. If it gives you a hard time, just turn it in, then turn it out, and it should start coming pretty easy, once that oil works down inside the threads, and once you get it out, you're good to go. There you go. An easy way to loosen rusty nuts, bolts, and screws.
