If heating or hammering is not possible the penetration can be improved by first spraying brake cleaner on the stuck fastener and following with the penetrating spray before the brake cleaner has evaporated. The solvent penetrates better than oil and will pull some oil with it. | If heating or hammering is not possible the penetration can be improved by first spraying brake cleaner on the stuck fastener and following with the penetrating spray before the brake cleaner has evaporated.

| + | If I could have only one chemical tool, it would be "Liquid Wrench". Note that when trying to loosen rusty parts, it's important to first remove as much of the rust as possible with a wire brush. Once it's as clean as a wire brush will get it, apply Liquid Wrench, then give the piece repeated light taps with a hammer for ten or fifteen seconds; this helps work the Liquid Wrench into the crevices. Wait two minutes, then repeat the Liquid Wrench/tapping procedure. After repeating the procedure 3 or 4 times, THEN try to loosen it with one swift blow. Sometimes it won't work, but the majority of the time, your patience will allow you to not only remove the rusted nuts and bolts, but to possibly even reuse them. | ||

| + | Many people recommend "PB Blaster", which led to me trying it - it did an excellent job for me. An overnight soak-in is an important step. | ||
