How to Clean a Pottery Studio Without Spreading Dust

By Christina Phillips, safety professional and potter · September 2026

Here's the irony of studio cleaning: the most common method — dry sweeping — is also the most effective way to fill the air with the respirable silica you're trying to get rid of. Clean wrong and you're worse off than not cleaning. Clean right and dust control becomes a habit, not a project.

Rule one: water beats brooms

Water keeps particles out of the air — it's the single most effective dust control in the studio, and it costs nothing. The routine:

• •Floors: wet mop, never dry sweep. A mop and bucket (or a wet Swiffer-style mop) after dusty sessions.
• •Work surfaces: wipe down wedging tables, wheel trays, and ware boards with a damp sponge or cloth.
• •Shelves and ware boards: damp-wipe before placing fresh work — dry clay dust settles everywhere.
• •Spills: wet them down first, then wipe or mop up. Never sweep a dry spill.

If you vacuum, it must be HEPA

A standard shop vacuum is a dust redistributor: fine particles blow straight through the filter and exhaust. If you vacuum dry studio material, use a true HEPA-filtered vacuum — one the manufacturer rates as HEPA, with filters maintained and replaced per instructions. Even then, wet methods first, vacuum second.

Clean top to bottom, dirtiest last

Dust settles downward, so work in this order: high shelves and lights, then work surfaces, then floors last. Clean the dustiest zones (mixing area, sanding station, around the kiln) after the cleaner ones, so you're not dragging contamination across the studio. Change mop water when it gets murky — dirty water just moves clay around.

The habits that prevent the mess

• •Contain scrap. Keep a covered reclaim bucket for scraps instead of letting dry bits accumulate on tables and floors.
• •Don't let dust build up. A quick damp-wipe at the end of each session beats a monthly deep clean — settled dust gets disturbed by every footstep.
• •Separate studio laundry. Wash dusty aprons and towels separately from household laundry, and shake them out outdoors — never indoors.
• •Wear your respirator while deep-cleaning. The dustiest air in the studio is often during cleanup. (See when to wear a respirator.)
• •Keep the studio door closed if it shares your home — cleaning stirs up dust, and you don't want it migrating to living areas.

A 10-minute end-of-session routine

Do that after every session and the "big clean" mostly takes care of itself.
