Introduction: Removing Rust With Baking Soda and Lemon Juice

I heard baking soda (sodium bicarbonate) and lemon juice on rust seems to break down the corrosion and make it removable. My results agree with that hypothesis. Not much more is required other than time and good old fashioned elbow grease. I've also added some water along the way since some people have said the lemon juice doesn't make that much of a difference.

These mufflers were from Magnaflow for the 2005 Pontiac GTO X-Pipe setup. They're 2.5" and I was upgrading to a custom 3". The whole setup ended up selling and I got a good price for it. So, for me, this was well worth the effort.

What an excellent improvement! I've used lemon juice for cleaning off grease before, but I've never combined it with baking soda. Great idea! Glad to be the first to welcome you to the great community that is Instructables!

Thanks! It was fun experimenting with something new. I really like this website and am looking forward to adding more content as I finish my other random projects :)

Well, I for one was impressed. How come I didn't notice your post sooner??? I have some rusty things I might try it out on around the house.

Just wondering - how well did you rinse it off? The lemon juice is acidic. If not totally washed off or neutralised somehow it might keep on biting into the metal and eventually eat it away. I guess now it's the new owner's problem. lol
