Most old equipment will have rust issues. I have been reading many suggestions ranging from PB Blaster and WD-40 to Acetone/ATF mixtures. WD-40 displaces water and helps loosen things up but does not dissolve rust. PB is a good penetrating oil but also doesn't dissolve rust. Acetone/ATF mixtures ? well I haven't tried it but ATF is really high detergent and acetone would certainly help it penetrate. I needed to clean the rust from the slip clutch parts on the 20" saw I'm restoring. I soaked the rusty parts in distilled vinegar, overnight, and brushed away the rust. Ever the chain links became freed up. After the soaking and brushing, I hosed them off and soaked them in WD-40 overnight. I could spend more time and get them cleaner, but I'm happy with these results.  Rust by Glen Ray, on Flickr |

Had no idea about the vinegar. Thanks for posting this, I already see myself saving hours of future sanding.

Looking good,
naval jelly works great for removing rust. wd40 is a good cleaner but little protection in the long run, It leaves a film that does provide some protection, but not if you wipe it off before it dries.
crc sp 350 is a good product also.

Some of the vintage bicycle guys and gals use oxalic acid solutions to remove surface rusts. I suspect its a bit stronger than the vinegar that you used, but should be safe for most metals that are not super delicate.

Vinegar is a mild acid. Good to hear a use besides descaling coffee maker. Auto parts sell spray products (Rust Fix?) that turns rust to a black primer. Used some two years ago on my vintage dump truck after sanding off paint and zero rust. Maybe some day it will see some paint.

Sure looks good! Vinegar has so many uses. It is one of my favorite go to home cleaners. Everything from store bought vegetables to floors. Didn't know about it as a rust remover. That is good to know.
I'm trying to teach myself silversmithing and am using vinegar and salt as a pickle solution. Works great (well I have nothing to compare to, but I'm pleased with the results).

Nice mild de-ruster, apple cider vinegar is a bit stronger then the distilled vinegar ,i use a mix of apple cider vinegar/water dilute strength to the amount of rust. More rust more vinegar. Less rust more water. After soaking and removing rust be sure to rinse thoroughly, |

Then rust "converters" are phosphates. Back in the day, before the epa people used to have entire car bodies dipped in phosphate tanks.

Another rust buster I've mentioned before is oil of wintergreen. Nothing better for penetrating rust frozen parts. It's expensive stuff. Not to be used for large soaking jobs. It can also be dangerous to use. Straight oil of wintergreen on the skin burns like fire. In the eyes it can cause blindness.
Oil of wintergreen is an old Navy trick that was used for freeing rusted parts in tropical salt water environments. It can also be used to drive ants, cockroaches, mice & other pests out of the work shop. Don't use it where cats & dogs can lick at it. It can cause severe liver damage in small pets.
It must be real oil of wintergreen, not the synthetic stuff you find in grocery stores as flavoring.
