CRC Industries Engine Tune-Up, Carburetor, Choke & Carbon Cleaners

CRC Industries: Precision Chemistry for Carburetor, Choke & Carbon Cleaning

When a carburetor starts hesitating, a choke sticks, or carbon deposits rob an engine of power, the right chemical solution makes all the difference. CRC Industries has built a decades-long reputation on exactly this kind of precision chemistry — purpose-built formulas that get into the tight spaces of fuel system components and restore them to like-new function. Their lineup of engine tune-up, carburetor, choke & carbon cleaners reflects that heritage, offering solutions for everything from everyday carbureted engines to the carbon-prone demands of modern gasoline direct injection (GDI) technology.

What Sets CRC Apart in This Category

CRC Industries is a leading global manufacturer of highly specialized chemical formulas, dedicated to providing the best solutions for both maintenance and repair professionals and DIY mechanics. That focus on specialization is clearly reflected in their carburetor and carbon cleaning products, where off-the-shelf solvents simply won't do.

The flagship CRC Carb & Choke Cleaner is a benchmark product in the category. It maximizes carburetor performance, improves fuel system performance, and ensures maximum fuel economy. It is formulated for automatic chokes, carburetor components, crankcase breather elements, EGR valves, heat risers, intake parts, and PCV systems, all with a low-VOC formula.

For those working on carbureted small engines — from lawn mowers and chainsaws to ATVs and marine applications — CRC's Clean-R-Carb spray is an equally versatile tool. Clean-R-Carb is a powerful and efficient formula designed to quickly dissolve deposits like gum, sludge, and varnish. The aerosol spray makes it convenient for cleaning parts in place without any disassembly, a key advantage when working around tight engine bays or mounted small-engine components.

Tackling Modern Engine Carbon Challenges

Carbon buildup isn't just a carbureted-engine problem — modern GDI engines are especially vulnerable. Because GDI injectors spray fuel directly into the combustion chamber instead of over the intake valve, there is no fuel wash to keep the valve clean. Over time, baked-on carbon deposits accumulate and cause rough idle, reduced power, and poor fuel economy. CRC addresses this with the GDI IVD® Intake Valve & Turbo Cleaner, which uses PolyEther Amine (PEA) detergency, with PEA molecules lifting carbon deposits and burning or flushing them out via the exhaust system. CRC offers the highest PEA concentration in the market, delivering a fast and thorough cleaning that also helps prevent future carbon buildup.

For broader engine decarbonizing tasks, the CRC Engine Tune Up & Decarbonizer breaks down carbon buildup and other harmful engine deposits left behind by modern fuels, and dramatically improves engine performance and power while solving many rough-idle problems. It is rated for all 2- and 4-cycle engines, making it a versatile choice for auto, marine, and outdoor power equipment alike.
