How to Clean and Sanitise Your Tweezers Properly

A precision tweezer can last decades if you clean it correctly. The vast majority of tweezers that 'go blunt' have actually been damaged by cleaning, not by use.
Use isopropyl alcohol — nothing else
70% or higher isopropyl alcohol on a cotton pad or a lens wipe. Wipe the tips and the inside of the arms. Air-dry. That's it.
Never use acetone, bleach, or abrasive cleaners
Acetone strips coatings (rose gold, matte black, etc.) within a few cleans. Bleach pits stainless steel. Abrasive sponges micro-scratch the tip alignment.
Sanitise after every brow session, not just monthly
Skin oils and product residue build up on the inside of the tips. A 10-second wipe after each use keeps the grip sharp and prevents bacteria.
Store tips capped or in a sleeve
Most tip damage happens in drawers, not in use. Use the protective cap your tweezer came with — and replace it every time.
Frequently asked
Can I sterilise tweezers in boiling water?
Avoid it on coated finishes — heat can affect the coating. For stainless steel tools, isopropyl alcohol gets you to the same level of sanitation without risk.
How often should I clean my tweezers?
After every use, even if it's just one or two hairs. It takes 10 seconds and roughly doubles the lifespan of the tool.
What dulls a tweezer fastest?
Dropping it tip-first, using acetone-based cleaners, and storing it loose in a drawer.
