Can towels or cloths contaminate sterilized bottles and equipment?

Expanded Explanation

Yes, towels and cloths can contaminate sterilized bottles and equipment even when they seem clean. Fabric easily picks up dust, lint, detergent residue, skin oils, and microorganisms from the kitchen environment. Once a bottle or funnel has been sterilized, wiping it with a cloth can undo that whole step immediately.

This is especially important for the inside of bottles, the mouth of jars, and any tool that touches the liqueur directly. A towel may also leave fibers behind, which are not only unhygienic but can end up floating in the finished liqueur. Moist cloths are an even bigger risk because damp fabric can carry more microbes than dry surfaces.

The safest approach is to let sanitized equipment air dry naturally on a clean rack or to use it while still warm after sterilization. If drying is necessary, use methods that do not involve household cloth. Protecting sterilized equipment from recontamination is just as important as the sterilization itself.
