Carburetor Cleaner

Carburetor cleaner is a specialized chemical solvent formulated to remove the varnish, gum, and carbon deposits that build up inside the complex air and fuel passageways of an engine’s carburetor. This accumulation of fuel residue often leads to issues like rough idling, difficult starting, and poor engine performance due to restricted fuel and air flow. The cleaner works by using a powerful blend of fast-acting solvents that chemically break down these hard residues without requiring extensive mechanical disassembly of the component. The primary goal of this chemical action is to restore the precise function of jets, metering rods, and throttle plates, ensuring the engine receives the correctly atomized fuel-air mixture it needs for efficient operation.

The composition of carburetor cleaner is dominated by powerful organic solvents, which are categorized as volatile organic compounds (VOCs). Common solvents include acetone, which can make up a significant portion of the mixture, and aromatic hydrocarbons like toluene and xylene, which are highly effective at dissolving petroleum-based residues. These solvents are selected for their ability to aggressively break down the sticky, polymerized fuel residues left behind by gasoline evaporation. Methyl ethyl ketone (MEK) is another solvent frequently used in these formulations, serving as a robust degreaser.
