Grease Trap Cleaning

The complete restaurant and food outlet guide to grease trap cleaning

Grease trap cleaning is a concern for many businesses and organisations that prepare and serve food. These include companies with canteens, entertainment venues, and public buildings.

Obviously, restaurants and other food outlets, in particular, need to know how to maintain grease traps effectively. Grease traps are devices installed in the drainage system to prevent liquified fats and oils from getting into drain and sewer pipes, where they can cause blockages and damage water treatment equipment. Grease traps are a vital pollution control measure. As such, their maintenance must be taken seriously.

If your business or restaurant has installed a grease trap, there are some important facts you need to know about grease trap cleaning.

Can I clean the grease trap myself?

There may be some grease trap maintenance that you or your staff can do without professional support. A grease trap should be cleaned regularly. The frequency will depend on the size of the restaurant or food outlet, and how much grease and oil is generated. As a guide, cleaning should take place when the grease trap is a no more than a quarter full of waste.

If you choose to conduct a basic grease trap clean yourself, do so with care. Detach the grease trap lid slowly to ensure no waste escapes, and you do not damage gaskets that seal the unit. If you need to remove any parts, note how they go back together.

However, do not take out any parts that you are not confident you can replace. Remove the solid waste using a tool of your choice, and place it inside a watertight container, such as a bag or box. Try to remove waste from the sides of the grease trap, too. Finally, replace the parts and lid of the grease trap to finish the basic clean.

What element of grease trap cleaning should I not try to do?

If you notice anything unusual about your grease trap, such as a missing or damaged part, do not try to clean it yourself. You do not want to risk damaging a machine that’s integral to your business. If your grease trap malfunctions, you could release grease and oil into a sewer, which could result in a pollution incident for which you would be legally liable.

Deep cleaning a grease trap is not advisable. You may not remove the food waste correctly. Using the wrong cleaning implements or cleaning fluids could damage the grease trap, preventing it from functioning properly. Also, large quantities of congealed grease and oil waste can be difficult to remove and to dispose of easily and legally.

If you have any doubts about how to carry out grease trap cleaning, or your device needs a deep clean, you should seek professional advice from a grease trap cleaning company. It will have the expertise to dispose of grease trap waste legally, and can advise you about on-going grease trap maintenance, and repair, if damage has occurred.

You may not want to carry out food grease trap cleaning on your premises yourself. You may not have time to carry out the cleaning. You may not have the skills. Or you may want to seek professional help as a due diligence measure to prove you take pollution control seriously.

If so, you can arrange a regular cleaning and maintenance schedule with a food grease trap cleaning company. This gives you peace of mind. Also, in the long-term, your business will save on costs associated with blocked pipes and plumbing problem.

Correct food grease disposal procedures

Good grease and oil should always be disposed of properly to prevent pollution harm to the local environment and blockages of plumbing and drainage systems. While you may have the best of intentions when disposing of grease and oil, ignorance of your legal requirements is not a defence against prosecution.

An industrial cleaning company, with the right grease trap cleaning expertise, will always ensure your grease trap is cleaned properly, that food waste is disposed of at an authorised waste disposal site, and that you have a record of the process to show your business has complied with all legal requirements.

Grease traps are vital for many restaurants. However, they can be a challenge to maintain correctly and legally. Effective grease trap cleaning is vital. Always speak to a reputable waste management company for advice on what cleaning schedule is best for your business.
