Brake & Carb Cleaner


Brake and carburetor cleaners normally contain solvents. Their use can contaminate other, non-hazardous solvents. An aerosol can that will not function properly but is still full may be a hazardous waste. Under intense heat, chlorinated solvents usually break down into toxic substances. Examples of chlorinated solvents are: CFCs, Carbon tetrachloride, 1,1,1 Trichloroethane, Chlorobenzene, Tetrachloroethane, andMethylene Chloride. Look at Material Safety Data Sheets (MSDS) to determine if your cleaners contain chlorine. 

  • consider replacing brake cleaners and carburetor cleaners that contain chlorinated solvents with non/less hazardous cleaners
  • collect chlorinated brake cleaner or carburetor cleaner residue separately from other waste to avoid cross contamination
  • keep brake and carburetor cleaner containers closed when not in use to avoid evaporation
  • manage your spent chlorinated brake cleaners, carburetor cleaners, and cleanup residue as hazardous wastes
  • dispose of brake or carburetor cleaner down any storm drain, or into a septic system, dry well, sewer, dumpster or on the ground
  • use chlorinated brake or carburetor cleaners in or around other solvents. Do not mix them with any other solvents (e.g. parts washers) by spraying them over the open parts washer, or over open pans used to collect antifreeze or used oil
