Can Isopropyl Alcohol or acetone from my medicine cabinet be used as a degreaser when bonding a strain gauge?
Solvent degreasers that are used to remove surface contaminates like oil, grease, etc. should leave nothing behind other than a contaminate-free surface. While there are a number of solvents available that are effective in removing contaminates like oil, some leave behind a residue that can inhibit proper strain gage sensor bonding. For example, acetone is an aggressive degreaser, but it leaves behind a white residue.
