Is CLR strong enough for REALLY rusty components?
I've searched and read several threads regarding rust and how to deal with it. We had some CLR in the garage already, so I thought I would give it a shot, but I wonder if it's strong enough to do the job in this case.
My parents picked up a free bike over the weekend, but the owner lived right next to the ocean. And they left the bike outside. So as you could probably guess, they have a little bit of a rust problem. They gave me a call and asked if I had any ideas. I didn't think it could be fixed at all at first. The following pic should give you an idea of what I saw:
So I took the bike home and removed some of the components, and tried putting them in a bath solution of CLR and hot water.
Here's what what those cantilever brake parts (and some other bolts and such) look like after a little bit of wire brush scrubbing, and at the two and a half hour mark of the CLR soak:
My question is for those of you who are really experienced with this: After almost three hours of letting it set, is this about the best that I should expect from CLR? It had been bubbling quite a bit at first, but now the bubbles seem to have stopped. Should I just leave these parts in here as is soaking for a few more days for better results? Is this stuff still working? Or do I need to go out and grab some wood bleach and some safety goggles to get the job done?
Appreciate any advice you have.
BTW: Yeah, the chain was really rusted too, but I was able to get it to turn using some liquid wrench and working it a bit with some pliers. It's a cheap a** bike, so I don't want to put a lot of money into it, just clean it up a bit and get it rolling.
