How do you unscrew a small electronic screw without a screwdriver?
How do you unscrew a small screw that won’t budge? Here are a few tricks to coax out a stubborn Phillips screw. At the first sign of trouble, spray the screw with rust penetrant (Liquid Wrench and PB Blaster are two really good brands). Let the penetrant work for at least 15 minutes. Then spray it again and tap the screw head dead-on several times with a hammer.
What to use if you don’t have a tiny screwdriver? If you’re dealing with a single-slot screw, head to your kitchen or wallet for an alternative to a screwdriver. The first thing you could try is a kitchen knife. Choose one that has a rounded tip like a butter knife or a small knife that you would use for a cheese board.
