How to Clean Rust Stains From an Exhaust Manifold

What You'll Need
Lemon Juice
White Vinegar
Nylon Scrub Pad
Clean Rag

An exhaust manifold can suffer from many serious and complex problems. However, there are many problems that are definitely simple enough for anyone to fix on their own. One of these problems is stains caused by rust. If something near your manifold is rusty, some may be carried to it by water and stain it.

Step 1 - Testing the Ingredients

Both lemon juice and white vinegar can remove rust stains. However, the one that works better will vary. Because of this, it is a good idea to test both if you have them available. If you do not, you may opt against tracking down the one you are missing and simply using the one you have.

However, if you have both, it is a good idea to try them out in small amounts on separate areas of your exhaust manifold to see which one is better. Make your selection and continue.

Step 2 - Removing Stains

Scrub the manifold with the scrub pad, using it to apply your cleaning ingredient of choice.

Step 3 - Finishing Up

Once you have removed all of the rust stains, finish up by rinsing them away. After you have done this, pat the manifold dry with your clean rag.
