Deep Cleaning Your Kitchen for Celiac Safety

Whether you’re newly diagnosed, moving into a new place, or just want to reset your kitchen, a deep clean can give you peace of mind about your cooking environment.

Here’s how to thoroughly decontaminate a kitchen.

When to Deep Clean

• After celiac diagnosis
• Moving into a new home
• After having guests who cooked with gluten
• If you’ve been getting sick and can’t find the source
• Periodic reset for peace of mind

The Basic Principle

Gluten is a protein. It sticks to surfaces but can be removed with thorough cleaning. The goals:

1. Remove visible residue
2. Clean surfaces that contact food
3. Replace what can’t be adequately cleaned
4. Establish systems to prevent re-contamination

Room by Room

Countertops

Non-porous surfaces (granite, laminate, stainless steel):

• Wash with hot soapy water
• Pay attention to seams and edges
• Rinse thoroughly
• Safe for GF food prep after cleaning

Porous surfaces (butcher block, tile with grout):

• Wash thoroughly
• Grout may harbor residue
• Consider sealing or dedicating a separate prep area
• Some celiacs use cutting boards on top

Sink

Cleaning:

• Scrub entire sink with soap and water
• Include the faucet and handles
• Clean the drain area
• Replace sponges

Ongoing:

• Consider separate sponge for GF dishes
• Don’t let gluten dishes soak where GF dishes will be washed
