Title: Rusty Chassis
Post by: HommeMarrBuckley on September 11, 2015, 07:19:24 pm
Im gonna break,  Im gonna break myyyyy........Im gonna break my rusty....chassis.....and run!!


Hello


Just thought I would share something (perhaps some of you already know) that gave me results that I was quite impressed with.  I wished I had taken a better shot of the rust on this chassis to better exhibit the before and after, but it had a decent amount.  I used apple cider vinegar with some water and just let it soak.  It was recommended to go 24 hours but I noticed after 5 to 10 minutes it was eating away.  I used some steel wool and scrubbed.  It was all gone in no time.  Interestingly enough, the rust would come back if left alone so I scrubbed to satisfaction and then dried it immediately.  It was recommended to neutralize the acid with baking soda but I grew up in the 80s and skipped that step and went right to sealing/lubing it.  Here are the results.  (Hesitant about using this with the transformers.  I was thinking about dipping the brush in the solution and just scrubbing the exterior could be safe.)

Nice
I've bathed rusty axe heads, anchors, what have you in vinegar (white vinegar will do too) overnight or for a couple days and it really does wonders

What a difference. What ratio vinegar/water did you use?

What ratio vinegar/water did you use?

I used two 32 oz. bottles (total $3).  I didn't really calculate so much because it took me twice as much time to find a container than the whole cleaning process and I got impatient.  Tricky to find one that could house both chassis enough to submerge them.  It was about 2-3 times water to vinegar.  I think it depends more on the degree of the rust.  More rust--More vinegar than water.  It was pretty simple. Especially considering I was kinda haphazard but astonished at the result.  All in all, cheap, non harsh chemical, super easy and effective way to remove rust.
