How to Deep Clean Your Kitchen Equipment (Restaurant Cleaning checklist)

Neglecting to deep clean kitchen equipment can have detrimental effects on your restaurant. Deep cleaning is designed to reduce the spread of viruses as well as remove dust and clutter.

It’s crucial to note that regular cleaning is not a substitute for deep cleaning. Deep cleaning involves cleaning and sanitising surfaces, corners, and kitchen equipment.

Because restaurants prepare food in kitchens, always sanitise kitchen equipment to avoid contamination.

Studies show that over 200 diseases are transmitted through contaminated foods each year.

Therefore, maintaining hygienic equipment is mandatory for a healthy kitchen environment. This is because the kitchen is a room prone to the growth of disease-causing bacteria and pests.

Let’s look at how you can deep clean each of your kitchen equipment.

Without a doubt, ovens are the backbone of any restaurant kitchen. They are regularly used and thus prone to accumulation of grease, food particles, and other debris.

You should not wait to see smoke from your oven to start cleaning it.

  • Oven and Grill Heavy Duty Cleaner
  • Gloves
  • Microfiber cloths


How to Do It Right

  • If the oven has just been in use, allow it to cool down before you start deep cleaning.
  • Take out all the oven racks and clean them separately using an Oven and Grill Heavy Duty Cleaner and warm water.
  • Wipe the inside of the oven using a wet microfiber cloth.
  • After you have thoroughly cleaned the oven and the racks, put them back to their original positions.

The primary concern of many restaurants is to keep food safe for consumption.

You don’t want to waste money on an underperforming refrigerator. This is because a clean refrigerator keeps food at a safe temperature and improves its overall performance.

Always follow the instruction of your fridge manufacturer when cleaning it.

Necessary Chemicals and Tools

  • Gentle surface wipes
  • Regular dishwashing liquid
  • Warm water
  • A basin
  • Baking soda or sodium bicarbonate


How to Do It Right

  • Take out food from the refrigerator and ensure it’s empty.
  • Take out all parts of the fridge that are removable, such as drawers or shelves.
  • Mix regular dishwashing soap with warm water in a basin and let the drawers soak before you rinse and wipe them.
  • Use gentle surface wipes with a combination of warm water and dishwasher soap to clean the surface of the refrigerator.
  • For stubborn stains, apply a mixture of baking soda and a little water. Leave the paste (water and baking soda) for about one hour before wiping it out.

How To Deep Clean Your Restaurant’s Grills

It’s recommended that grills be cleaned at least once a day. This reduces cross-contamination and decreases the possible accumulation of stubborn grease stains.

Necessary Chemicals and Tools

  • Stiff wire brush
  • Spackle knife or sturdy spatula
  • Shine Multipurpose Polish
  • Baking Soda or sodium bicarbonate
  • Paper towel or rags
  • Water with soap

How to Do It Right

  • Remove the charcoal and ash out of the grill in case your restaurant is using a charcoal grill.
  • If you have a gas grill, disconnect its propane tank and set it aside from the grill.
  • Get the grill hot by firing it up for a minimum of 30 minutes. Extreme temperatures will remove stuck-on food and grease.
  • While the grill is hot, pour one cup of cooking oil onto its surface.
  • After the grill has cooled, remove all grates.  Submerge them in warm, soapy water for about 30 minutes.
  • For stubborn gunk, mix baking soda and a little water and apply the paste on caked-on food bits.
  • After grill grates have been removed, use a spackle knife to remove any stuck-on substance from the firebox of the grill.
  • Dip the stiff wire brush in a bucket of warm soapy water. Use it to scrub off all carbon from its grates and panels.
  • To ensure effective decontamination, soak a paper towel or rag in cooking oil and scrub the surface of the grill.
  • As a final touch, use the Shine Multipurpose Polish to polish the grill.
  • Once the grill is clean, reassemble all parts that were previously removed.
