How to clean the vacuum guage sensor
I have YJ vacuum guage, also watch the tech tip "sensor cleaning" form youtube.
However, I cannot get Zep Aerosol Solvent Degreaser in MA, this product is restricted from many states. Any people tell me what substitution I can use to clean my sensor.
moved to tools and test equipment
Are all aerosol solvents restricted? I used this on my Supco VG64:
If it's available, it should be at your local auto parts store.
Reading was spot-on after cleaning. Denatured alcohol is the "recommended" cleaner. I had the gauge apart to fix a leak and decided to clean it with this stuff while I had it open.
not all aerosol solvents are restricted, but YJ showed the restricted solvent which is restricted in many states
This item has been restricted from sale in the following states: [CA, CT, DC, DE, IL, MA, MD, ME, MI, NH, NJ, NY, OH, PA, RI, VA]
Maybe I try the following from grainger : http://www.grainger.com/Grainger/wwg/itemDetails.shtml
I would hesitate to use that. According to the MSDS it's mostly acetone:
Depending on what kind of plastics are in your gauge, the acetone could damage them. My Supco has the thermistors sealed to the brass fittings with epoxy. Epoxy is generally pretty resistant to solvents (even acetone), but to me it's not worth a chance on something that expensive.
The electronics cleaner I mentioned is advertised as safe for plastic, and contains no acetone. MSDS:
Basically anything that isn't too aggressive and evaporates completely should work nicely.
rubbing alcohol is what is recommended by everybody.
