Understanding your specific griddle type is the first step in determining the best cleaning approach. If you’re unsure, consult your equipment manual or contact the manufacturer.

Daily Cleaning Routine for Commercial Griddles

Daily cleaning is essential for maintaining food safety and griddle performance. This routine should be performed at least once daily, typically at the end of service.

Step 1: Safety First

Before beginning any cleaning procedure:

Turn off the griddle and allow it to cool to a warm temperature (around 150°F/65°C)
Never clean a completely cold griddle as this makes grease removal more difficult
Similarly, never clean an extremely hot griddle as this creates safety hazards
Ensure you have appropriate heat-resistant gloves if needed

Step 2: Scrape Off Debris

Once your griddle has cooled to a warm temperature:

Use a griddle scraper with a straight edge (metal for steel griddles, plastic for chrome griddles)
Working from back to front, push all food particles and grease into the grease trap
Wipe the scraper clean between passes using a heat-resistant cloth
Pay special attention to corners and edges where carbon builds up

Step 3: Apply Cleaning Solution

For standard daily cleaning:

Pour an appropriate amount of griddle cleaner onto the warm surface
- Use a commercial griddle cleaner formulated for your griddle type
- For chemical-free options, a mixture of vinegar and water (1:4 ratio) works well
Spread the solution evenly across the surface using a cloth or scrubber holder
Allow the solution to work for 3-5 minutes (follow product instructions)

Step 4: Scrub the Surface

For steel griddles: Use a grill brick or griddle screen to scrub in circular motions
For chrome griddles: Use a non-abrasive pad or specialized chrome griddle cleaning pad
Apply even pressure and work methodically across the entire surface
For stubborn areas, add more cleaning solution and let it dwell longer

Step 5: Rinse Thoroughly

Use clean water to rinse the surface
- Many commercial kitchens have a water pitcher dedicated to this purpose
- Some griddles have built-in water troughs for easy rinsing
Scrape the water and dissolved grime toward the grease trap
Repeat rinsing until water runs clear and no cleaner residue remains
Use a clean, dry cloth to wipe down the entire surface

Step 6: Re-season the Surface

While the griddle is still warm, apply a thin layer of cooking oil
Use a clean cloth to spread the oil evenly across the entire cooking surface
Allow the oil to heat until it stops smoking
Wipe away excess oil with a fresh cloth, leaving only a microscopically thin layer

This daily cleaning routine typically takes 10-15 minutes but saves significant time and maintenance costs in the long run by preventing carbon buildup and extending equipment life.

Deep Cleaning Methods for Stubborn Residue

Even with regular daily cleaning, commercial griddles occasionally need a more intensive cleaning to remove stubborn carbon buildup or discoloration. This deep cleaning should be performed weekly or monthly, depending on usage volume.

Ice Method for Stubborn Carbon

The ice method is particularly effective for removing baked-on carbon from steel griddles:

Heat the griddle to approximately 300°F (150°C)
Turn off the heat and immediately place ice cubes across the surface
As the ice melts, the thermal shock causes carbon to loosen
Use a griddle scraper to remove the loosened debris
For extremely stubborn areas, add water to the still-hot surface to create steam
Scrape again while the steam helps lift additional residue

Safety Note: Stand back to avoid steam burns when applying ice or water to hot surfaces.

Vinegar and Water Method

For a chemical-free deep cleaning approach:

Heat the griddle to approximately 250°F (120°C)
Mix equal parts water and white vinegar
Pour the solution onto the griddle surface
Let it bubble and steam for 5-10 minutes
Scrape the loosened debris and wipe with a cloth
Rinse thoroughly with clean water
Finish with proper re-seasoning

Commercial Griddle Cleaners for Heavy-Duty Cleaning

For especially difficult cleaning situations:

Choose a commercial-grade griddle cleaner appropriate for your griddle type
Follow the exact manufacturer’s instructions for temperature and application
Allow proper dwell time as specified (usually 5-15 minutes)
Use the recommended scrubbing tool (brick, screen, or pad)
Rinse multiple times to ensure all chemical residue is removed
Neutralize any remaining cleaner with a vinegar-water solution if recommended
Re-season thoroughly

Addressing Rust on Steel Griddles

If your griddle has developed rust spots:

For light rust, scrub with a griddle screen or fine steel wool
For moderate rust, use a commercial rust remover formulated for food-contact surfaces
Apply the rust remover and allow it to work as directed
Scrub thoroughly, rinse completely, and dry immediately
Apply several layers of seasoning oil, heating between applications
Repeat the seasoning process 3-4 times to rebuild protection

Remember that deep cleaning removes the protective seasoning layer, so proper re-seasoning afterward is crucial for optimal cooking performance and to prevent future rust or sticking issues.

Chemical-Free Cleaning Options for Commercial Griddles

Many food service operations prefer to minimize chemical use in their kitchens, particularly on cooking surfaces. Here are effective chemical-free methods for cleaning commercial griddles.

Using a Grill Brick

A grill brick (also called a griddle brick) is a pumice-like abrasive block specifically designed for cleaning flat top cooking surfaces:

Heat the griddle to approximately 300°F (150°C), then turn off
Pour a small amount of water or oil on the surface to act as a lubricant
Using a holder or heat-resistant gloves, scrub the surface with the grill brick
Apply firm, even pressure in circular or back-and-forth motions
The brick will gradually wear down as it removes carbon and residue
Wipe away the slurry with a cloth and rinse thoroughly
Re-season the surface properly

Note: Grill bricks should only be used on steel griddles, never on chrome or non-stick surfaces.

Lemon Juice Method

Lemon juice is naturally acidic and can help break down grease and light carbon:

Heat the griddle to medium temperature
Cut several lemons in half
Using tongs, rub the lemon halves over the griddle surface
The acid and steam will help loosen residue
Scrape away the loosened debris
Rinse with water and wipe clean
Apply seasoning oil

Soda Water Method

The carbonation in soda water can help lift grease and light residue:

Heat the griddle to medium temperature
Pour club soda or seltzer water onto the surface
The carbonation will bubble and help release stuck-on food
Scrape and wipe the surface clean
Rinse with fresh water and re-season

These chemical-free methods are particularly valuable for kitchens focusing on natural or organic food preparation, where chemical residue is a concern. They’re also excellent options for cleaning flat top grills without chemicals, a growing preference in many food service establishments.
