Let’s break this down by material and technique.
How to Clean Stainless Steel Motorcycle Exhausts
Stainless steel exhausts are durable and resilient, making them easier to clean compared to chrome.
Tools You’ll Need:
- Mild acid-based cleaner (vinegar or toilet cleaner with HCl)
- Microfiber cloths
- Soft wire brush
- Rubber gloves
- Bucket with lukewarm water
Step 1: Remove Surface Debris
Before you begin, make sure the bike is cold. Pre-rinse the exhaust with water to loosen dirt. Use a medium-pressure hose.
Step 2: Apply Acid-Based Cleaner
To clean stainless steel properly, apply a mild acid (like vinegar or 9% HCl toilet cleaner). These dissolve grime and oxidation without damaging the metal.
Apply the cleaner with a soft cloth and let it sit for 3-5 minutes. Avoid using strong acids that can damage the surface.
Step 3: Scrub and Rinse
Use a soft wire brush or sponge to gently scrub the exhaust. Rinse thoroughly to remove acid residue.
Step 4: Polish the Metal
After drying with a microfiber towel, apply a stainless steel polish to protect the pipe and restore shine.
How to Clean Chrome Motorcycle Exhausts
Chrome pipes are more delicate and prone to scratches and corrosion.
Materials You’ll Need:
- Automotive shampoo or mild soap
- Microfiber cloths
- Chrome-safe polish
- Foam applicator
Step 1: Wash with Soap and Water
Mix mild soap or auto shampoo in a bucket of lukewarm water. Soak a microfiber towel and gently wash the chrome. Avoid abrasive tools.
Step 2: Rinse and Pat Dry
Use clean water to rinse off soap. Dry by patting with a microfiber cloth to prevent scratches and water spots.
Step 3: Polish with Chrome Cleaner
Apply a small amount of chrome polish with a soft applicator. Buff gently in circular motions until the surface shines.
