A Clean Bench Is Not Enough: Check the Underside of the Bottle

A clean bench can become contaminated as soon as a dirty bottle is placed on it.

Updated · NANOLAB Knowledge

A clean bench can become contaminated as soon as a dirty bottle is placed on it. The underside is easy to overlook because it is rarely visible during normal dispensing. Include bottle bases in the setup sequence, especially when equipment moves between a mobile kit, floor storage and the coating bay.

Trace the transfer route

Consider a common sequence: a bottle rests on the floor, moves to the bench, and is followed by a clean towel on the same spot. The towel can pick up grit without ever touching the floor itself. Cleaning the bench only at the start of the day does not prevent that later transfer.

Inspect the bases of incoming containers and clean them with a compatible method. Keep exterior-cleaning cloths away from finishing stock. Check trays and shelving that contacted the dirty base, rather than moving the bottle and leaving its deposit behind.

Avoid setting bottles directly onto folded clean towels as a way to protect the bench. This makes the towel part of the contamination route and obscures which items remain suitable for paint.

Give containers a defined position

Use a clean, stable tray or designated bottle area separate from applicators and towels. Keep the arrangement simple enough that visiting operators and mobile staff can follow it without explanation. Label any container with a leak or uncertain contents and remove it from active use pending resolution.

At close-down, lift containers and inspect underneath instead of wiping around them. Repeated deposits can reveal a leaking cap, product running down the side or a dirty transport box. Correct the source so tomorrow's clean bench remains a reliable work surface after the first bottle arrives.
