No one wants any part of their trailer to rust, but rusty springs can negatively impact your suspension, leading to costly repairs. We have compiled a list of simple and popular methods to remove rust from trailer parts like springs, but remember: if your trailer spring is significantly rusted, the safest course of action is to replace it. Damaged springs will hinder your trailer’s use.
Using an abrasive material such as steel wool, a wire brush, or sandpaper to remove the surface rusting. Deeper rust might not be affected, but scrubbing away the worst of the loose particles may be easier than you think.
The acidic nature of white vinegar makes it a useful weapon against rusting objects, and many people swear by its efficacy. Simply place your spring in a container with vinegar, swish it around, and then let it sit for a day or more. The longer the spring is in the vinegar, the longer the acid has to corrode the rust.
3. Baking soda
Dig into your pantry, mix some baking soda and water into a thick paste. Apply the paste (it shouldn’t run; if it does, add more baking soda) and let it dry. Then use a brush to remove the paste and rust. For small or hard to reach areas, as might be found on a trailer spring, a stiff toothbrush works better than you might think!
4. Lemon juice and salt
Depending on the location of the rust, this solution might be the one for you. Rub salt over the rusted area and then squeeze lemon juice atop of the salt. Leave to sit for a few hours and then scour the rust away. Steel wool works well, but should be used gently, so as not to damage the metal further. This method is best used on small patches of rust in easy-to-access areas.
5. Homemade and store solutions
Solutions can be found in most hardware stores, as well as all over the internet. Many of the homemade ones include some combination of the methods we’ve listed here. If you’re feeling particularly adventurous, you could try making your own! Remember, the key to removing rust often lies in a bit of elbow grease (such as method 1) and some corrosive substances (2-4).
