went to clean my Mass Air Flow Sensor (MAF), and found out there is such a thing as MAF Cleaner. so what is different about it? why are there carb cleaners that say they can be used on O2 sensors and MAF, and if that's the case why can't I just use the can of Gumout carb cleaner I have on the shelf?
some of the cans list some of the ingredients. some said acetone, some said toluene, some didn't say anything. so I looked up the SDS (Safety Data Sheet) on their websites, which seems like it's sort of required to have that, to see what the chemicals are.
they won't list exactly what chemicals and exactly how much, because their trade secrets are more important than a medical emergency with your eyeballs. big corporations can do that.
these are the few examples I looked up:
Gumout MAF Cleaner <--- no acetone
item# 540041
naphtha, 50-75%
n-heptane, 10-25%
CO2, 2.5-10% v/v
n-hexane, 2.5-10%
methylcyclohexane, 2.5-10%
methanol, 0.1-10%
Gumout Carb/Choke Cleaner
item# 800002231
acetone, 60-100%
tolune, 5-10%
CO2, 5-10% v/v
Gumout Restore Brake Cleaner/Degreaser
item# 540001
acetone, 60-100%
toluene, 5-10%
CO2, 5-10% v/v
Berryman Brake Cleaner <--- no acetone
item# 2420-DP
isohexane, 80-90%
ethanol, 5-10%
2-propanol, 1-2%
CO2, 4-8% v/v
CRC Brakleen chlorinated
item# 1003711
tetrachloroethylene, 50-100%
CO2, 1-3% v/v
CRC Brakleen non-chlorinated
item# 1003662
acetone, 65-85%
CO2, 5-10%
light petroleum distillates, 1-5%
heptane (various), 1-5%
naphtha, 1-5%
n-heptane, 1-5%
observations:
1. Gumout "MAF Cleaner" doesn't have acetone, which is a very strong solvent. it uses naphtha and hexane instead.
2. some brake cleaners, which are supposedly gentler than Gumout, still have acetone.
conclusion:
yes, you should use use actual MAF Cleaner because it doesn't have acetone. you might be able to get by with Berryman Brake Cleaner because it doesn't have acetone either.
