Grease in kitchen sinks is mainly produced from everyday cooking and dishwashing activities. FOG is an abbreviation for fats, oils, and grease, which refers to sink grease. When FOG residues go down the drain, they start sticking to the pipelines, which work as a “trap” for water and other particles to drain down. This is where grease trap cleaning becomes more critical.
Grease trap cleaning is a professional process of removing accumulated fats, oils, grease, and solid food waste from the kitchen drainage systems. The grease trap cleanout involves pumping out the waste and scraping and washing the tank to prevent severe clogs, awful odors, and health code violations.
This essential guide to grease trap maintenance for restaurants will assist you in thoroughly cleaning and maintaining your kitchen plumbing system. However, this will also assist in cleaning and maintaining residential kitchen plumbing.

Mistakes To Avoid During Commercial Kitchen Grease Trap Cleaning
As we have already said, the grease trap cleaning is not your ordinary kitchen cleaning. However, as the name implies, you might get caught in this trap if you don’t follow the precautions. So, here are some of the mistakes to avoid when cleaning a restaurant grease trap. Additionally, avoiding these pitfalls will save you time, money, and hard work.

- Do not wait too long for a maintenance cleaning appointment. This is a serious mistake because excess grease can enter the plumbing system.
- Before starting grease trap cleaning, all connected kitchen equipment and sinks should be turned off.
- Some people only scoop out the grease that floats on the surface. However, grease traps also contain solid food particles and sludge at the bottom.

Effective Grease Trap Cleaning & Maintenance Tips:
Proper maintenance is the secret sauce for extending the life of your grease trap cleaning. However, begin by developing a regular maintenance schedule based on the needs of your kitchen. If your kitchen remains busy, then it might require maintenance after a month or two. In other cases, you may need it after 2-3 months.
Scheduled Maintenance:
Create a consistent maintenance schedule for your restaurant’s grease trap. A consistent grease trap restaurant schedule will prevent you from potential blockages. Acme Sewer & Drain Cleaning can clean and maintain your drains thoroughly.
Avoid Harsh Chemicals:
Do not use bleach, ammonia, or lye, as these damage the trap and plumbing. Instead, use bioenzymatic cleaners that digest fats, oils, and grease (FOG) and are safe to use, too.
Use Strainers:
Use strainers for grease trap maintenance. Install a solid interceptor or drain strainers to prevent large food particles from entering the trap.
Cool the Trap:
Cooling is critical when it comes to proper cleaning. Before cleaning, turn off all water flow and allow the trap to cool so that the grease solidifies and can be scooped more easily.
Scrape and Scoop:
Remove the lid and scrape all hardened grease from the walls and baffles with a wire brush.
Manage Grease Waste:
Dispose of grease in designated recycling barrels rather than flushing it. However, flushing it normally can cause serious issues. You may face fines for disposing of grease into the main sewer lines.
