Just realized I've been cleaning shutter blades wrong for probably 10 years. A tech in Tacoma pointed out my solvent was leaving a residue.

Yeah, I switched to 99% isopropyl alcohol a few years back for that exact reason. The stuff from the hardware store leaves way less film than most solvents.

Ugh, that sticky film is the worst. I mean, @lunab97 is totally right, it just smears everything. I used to get the 70% stuff from the drugstore for cleaning electronics and it was honestly useless. Felt like I was just wiping grease around with water. Switching to the stronger stuff from the hardware aisle was a total game changer. It actually evaporates clean and gets the job done right the first time.

Hardware store IPA is the real deal. I learned that the hard way after using the weak stuff from the pharmacy for ages and wondering why everything felt sticky. My first cleaning attempts were basically just moving the grime around. What do you usually use it for?
