Mechanics often use this product (with necessary tools) to clean injectors, throttle bodies, and other components to eliminate gum and varnish deposits prior to diagnosing engine ailments. The ingredients listed on the Sea Foam MSDS are Pale Oil (refined crude oil), Naphtha (a crude oil distillate) and IPA (Isopropyl alcohol).

SEA FOAM Motor Treatment is a petroleum based product that helps clean internal fuel and oil system components. SEA FOAM is an EPA-registered product, and will not harm engine components, seals, gaskets, catalytic converters or oxygen sensors.

SEA FOAM helps liquefy gum and varnish deposits helping to quiet noisy valve lifters. By using SEA FOAM to help eliminate varnish and deposit buildup, mechanics can more accurately diagnose mechanical problems that may exist. Mechanics also use Sea Foam in injector cleaning machines to clean injectors, air induction systems and Throttle Bodies. To clean Air induction systems and Throttle Bodies the use of an “s” tool attachment is necessary to soak down the Throttle Body with Sea Foam. Next a nylon brush is used to clean throttle plates and throttle body housing. That is why Sea Foam has been so popular with professional mechanics for over 65 years.

As a fuel system additive, Sea Foam will help clean carburetor jets and passageways, fuel injectors, helps clean deposits, adds lubricity to fuel, helps stabilize fuel for up to 2 years and helps control moisture.

As an oil system additive, Sea Foam helps clean varnish and oil residue deposits.

In our opinion Sea Foam Motor Treatment is best utilized by your mechanic for its cleaning properties. As an everyday fuel additive, it failed to rally excitement among our critics. But, who can argue with the fact the company has been successfully marketing this product for over 60 years. They’ve obviously been satisfying their customer base.
