Good question. Yes, soaking engine components or fuel system components (carb parts), transmission parts, and/or hydraulic system parts in a Sea Foam bath is a great way to clean parts.

Start with a slow cooker (crock pot). Either buy a new one for the kitchen (don’t use it for food again after using Sea Foam in it!), or purchase a cheap one dedicated to parts cleaning. Add enough Sea Foam Motor Treatment, High Mileage or Marine PRO to sufficiently cover the parts that need to be cleaned. Add the parts, put the cover on and turn the slow cooker on low or medium for 12-24 hours. After the “cooking time,” remove the parts and gently brush off the loosened contamination with a soft bristle brush or bottle brush to clean the remaining debris off the components. Pipe cleaners work great for small passageways. If there is still more contamination that needs to be cleaned, repeat the 12-24 hour “cooking time” and re-assess the parts. Hope that helps!

Thanks for the question!

I’d use High Mileage. It’s a strong cleaner formulated to clean stubborn residues and deposits in fuel and oil after years of buildup.
I’d add a full 16 oz can to a low tank of fuel (1/8 to 1/4 tank or so). Then, drive until almost empty before refueling (at least 20 miles if you can to give the High Mileage time to run through the fuel system). This creates a high cleaning concentration that works much faster and better than adding to a high amount of fuel.

Hi John. Yes, Sea Foam Motor Treatment can be used in ANY blend of gasoline and diesel fuel – always safe, easy, and works great to clean your engine’s fuel system!

HI Faith. Yes, you can use Sea Foam in your Honda Pilot’s fuel tank and oil crankcase. In fuel, will work to clean and lubricate fuel injectors and chamber areas. In oil, will liquefy heavy oil residues and deposits, improving oil flow. Hope this helps!
