LOW VOC CLEANER
A cleaner composition with improved cleaning of hydrophobic contaminants typically found on used brake assemblies and parts, including one or more low vapor pressure hydrocarbon solvents, one or more exempted volatile organic compounds, and a non-exempt volatile organic compound.
1 . A cleaner composition comprising:
20% to 45% by weight of a low vapor pressure hydrocarbon solvent;
50% to 80% by weight acetone; and
0% to 10% by weight heptane.
2 . The cleaner composition of claim 1 , further comprising:
about 25% by weight of a low vapor pressure hydrocarbon solvent;
about 65% by weight acetone; and
about 10% by weight heptane.
3 . The cleaner composition of claim 1 , further comprising 3% to 10% by weight carbon dioxide.
4 . The cleaner composition of claim 3 , further comprising:
about 25% by weight of a low vapor pressure hydrocarbon solvent;
about 60% by weight acetone;
about 10% by weight heptane; and
about 5% by weight carbon dioxide.
5 . A cleaner composition comprising:
20% to 45% by weight of one or more low vapor pressure hydrocarbon solvents;
50% to 80% by weight of one or more exempted volatile organic compounds; and
