### ⭐⭐⭐⭐⭐ works very well and has a lot of uses
*by D***L on 24 July 2025*

It works very well as is non conductive and a great degreaser, it works well as a fast drying "lubricant" to quickly position materials/items that need to be degreased and clean for their final seating positions. I use it all the time at work for cleaning circuit boards, flushing out hose pipes for flue gas analyser cells gas manifolds, cleaning flux from usb ports, and for automotive use it's fantastic at cleaning out electrical connectors. It isn't as strong as a defattening agent as pure isopropyl alcohol but as a pressurised aerosol the pressure helps displace some large deposits and like pure isopropyl alcohol it evaporates quickly in open air. Good stuff but rather expensive
