Dealing with rusted and corroded bolts, parts, etc...
Was wondering what others use for dealing with rusted and/or corroded parts that are stubborn to separate or loosen? There are several types of lubricates and grim eaters, as well as using heat with them.
I know PB Blaster is often recommended, but I've wondered if CLR would also do a decent job on removing rust and corrosion. Other then potentially damaging paint or finish, which may sometimes not be a concern anyways, would CLR work fine? |

I think the toughest thing CLR can remove is lime scale. I don't think it works well on rust(I've never seen it advertised as a rust remover).
PB works well. Sometimes you need to work the nut or bolt back & fourth, spraying it every couple back & fourths. |

Calcium Lime Rust. http://en.wikipedia.org/wiki/Calcium_Lime_Rust CLR is okay if you can immerse your rusty parts in a container of CLR. But it does not cling well to parts on a vehicle, so its of limited use. Rust-dissolving lubricants like "Liquid Wrench" dissolve rust, lubricate parts and cling to surfaces, and work better. |

Re: Dealing with rusted and corroded bolts, parts, etc...
I'm going to second that PB Blaster recommendation. It's the best product for rusted/corroded bolts that I've used.
The first time I used it... I had this rusted bolt I couldn't get off. I tried a variety of things for over a week. It was in the worse place (couldn't even cut it off). I was on the verge of attempting to drill it out when I sprayed it down with PB Blaster - that thing was off 5 minutes later. There's my PB Blaster commercial. I have used CLR in my heater coil to help clean out the dirt & grime... it works pretty good for that (but I agree with MagicRat - I think if you use CLR you will need to immerse what you want to clean). I also have Liquid Wrench - but I don't think it works anywhere near as well as PB Blaster because I had tried it on that afore mentioned rusty bolt and it made zero impact.
