The Complete Guide to AMSOIL Cleaners & Protectants
One product per job — purpose-built chemistry
AMSOIL splits cleaning, protection, and penetration into purpose-built products instead of trying to do everything from a single can. Power Foam attacks fuel-system and intake carbon. Engine and Transmission Flush cleans internals before an oil change. Metal Protector penetrates rusted threads, displaces water from electrical connections, lubricates hinges and cables, and lays down a long-duration corrosion-resistant film — all in one can. The expanded lineup adds dedicated products for brake service, off-road plastics, firearms, glass, chains, and seasonal storage.
Power Foam — the carbon, gum & varnish cleaner
AMSOIL Power Foam delivers as a clinging foam that stays on vertical surfaces inside carburetors, throttle bodies, intake tracts, and combustion chambers. The detergent-solvent package softens and dissolves baked-on fuel residue, gum, and carbon, restoring throttle response and stable idle on 2-stroke and 4-stroke gasoline engines — particularly small engines, motorcycles, and older carbureted vehicles.
Engine and Transmission Flush — pre-oil-change cleanup
Before switching to AMSOIL synthetic oil — or as periodic maintenance on a high-mileage engine — Engine and Transmission Flush loosens sludge and varnish from internal surfaces over a 15-minute idle. The detergent package suspends contaminants in the old oil so they drain out at the change. Always change both the oil and the filter immediately after flushing.
Metal Protector — penetrant, water displacer, lubricant & long-term rust defense
Metal Protector is the all-in-one answer to corrosion, seized hardware, and wet electrical connections. Sprayed onto bare or coated metal — tools, marine fittings, trailer hardware, stored vehicles, agricultural equipment — it penetrates seams, crevices, and rusted threads, displaces moisture from metal surfaces and electrical connectors, lubricates hinges and cables, and leaves a long-lasting protective film that resists humidity, road salt, and salt spray for months at a time. It replaces the traditional petroleum penetrant on the workbench while delivering long-duration corrosion defense in the garage, shop, marina, and farm.
Mudslinger® — non-stick protection for off-road plastics
AMSOIL Mudslinger® Mud and Dirt Repellent is the answer to the post-ride cleaning problem for ATV, UTV, and dirt bike owners. Applied to plastic panels, fenders, and bodywork before a ride, it creates a non-stick barrier that allows mud, dirt, and even packed clay to rinse off cleanly with low-pressure water rather than hours of scrubbing.
Beyond easy cleaning, Mudslinger also protects against UV rays — important for ATV and UTV plastic that sits in Florida sun between rides. It is the single most practical pre-ride product for any off-road machine.
Engine Fogging Oil — the right way to put equipment away for storage
When outboard motors, snowmobiles, generators, and small engines sit for months without fogging protection, condensation and oxygen attack bare metal cylinder walls, rings, and valves. AMSOIL Engine Fogging Oil fills those internal surfaces with a protective film that prevents rust from forming on 2-stroke and 4-stroke engines during the off-season.
For Florida boaters layering up their outboards for winter — or northern customers storing snowmobiles through summer — a single can of AMSOIL Engine Fogging Oil applied correctly can be the difference between a reliable spring start and an expensive bore and ring job.
Chain Lube and Spray Grease — shop and trail essentials
AMSOIL Chain Lube and Spray Grease round out the lineup for moving-part lubrication. Chain Lube's fling-resistant formula stays on motorcycle and ATV chains at speed while protecting against corrosion and wear — particularly important in wet or muddy conditions. Spray Grease delivers white lithium grease in a convenient aerosol, reaching tight pivots, slides, hinges, and hardware where a conventional grease gun cannot.
Pairs with AMSOIL motor oil, fuel additives & filters
These products are designed to work alongside the AMSOIL synthetic motor oil, fuel additive, and filter lineup. Use Engine and Transmission Flush before an AMSOIL oil change. Use Power Foam between fuel-system service and an AMSOIL P.i. Performance Improver fuel-additive treatment. The result is a cleaner, better-protected engine running on premium synthetic lubricants and filtration.
