Sterile technique at home
Sterile technique at home is eight habits, starting with twenty seconds of soap and water before anything is laid out. Among them: swab a stopper and let it air-dry, never touch the needle or a cleaned stopper, and use each needle once, the rule people break most.

"Sterile technique" sounds like a hospital thing, but at home it comes down to a short list of habits. The principle underneath all of them: anything that ends up inside a vial or under skin should only ever touch things that are clean.
- Hands first. Soap and water for twenty seconds, or alcohol gel if there's no sink. Do this before you lay anything out, not after.
- Clear the surface and wipe it. A wiped table or a fresh disposable prep mat beats a crowded worktop. Food, pets and phones off it.
- Open packaging at the last moment. A syringe sitting unwrapped and "ready" for ten minutes has been collecting whatever is in the air.
- Swab, then wait. Wipe the stopper with a fresh alcohol pad and let it air-dry for a few seconds. Alcohol does its work as it dries, and wet alcohol carried in on a needle is what stings.
- Never touch the business end. Not the needle, not the syringe tip, not the part of the stopper you just cleaned. If you do, that item is finished — start again with a fresh one.
- One needle, one use. Needles blunt on the first pass, so a reused one hurts more and is dirtier. This is the rule people break most and regret most.
- A fresh pad per surface. One for the water stopper, another for the vial. Reusing a pad just moves things around.
- Finish the way you started. Sharps into the container immediately, rubbish away, surface wiped.
If you drop something, if a cap comes off inside a bag, or if you simply can't remember whether a stopper was swabbed — bin it and use a new one. Consumables are cheap compared with the alternative.
