Our kitchen is supposed to be the place where we love to be.  Where we go to make amazing food for our friends.  To plate breathtaking arrangements to wow our customers.  Right?

But none of us like being in a kitchen that is covered floor-to-ceiling in grease.  It’s distracting, smelly and just plain-old gross.  


To get the lowdown on grease, read The what, where, why + how of kitchen grease.


Why is everything in my kitchen greasy?

There is a simple reason why everything in your kitchen is greasy: the oil from your cooking has nowhere to go.  As you stand over your wok, cooking that succulent stir-fry, small droplets of oil are spitting up into the air.  These droplets become so small that they can float on air.  This is a process called aerosolization.  Once oil has aerosolised, it will stick to almost anything.  That entire army of little grease aerosols must find a place to settle.  And settle they do.  They take up residence on your walls, your cabinets, your benches: any surface they can reach. 

This grease coating is the bane of any chef’s life.  But it does not need to be.  There are simple ways to deal with it.


How do I stop grease covering my kitchen?

  • You could pay a cleaner. This is a good option if you do not want to worry about dealing with any of the grease yourself.  However, having someone come in to clean can be a huge disruption to your kitchen.  Plus, in between visits the grease will build back up, making an unpleasant working environment for you and your staff. 
  • You could clean it yourself. A quick google search – ‘how to clean kitchen grease’ – offers a multitude of ways to clean grease yourself: soap and water, bleach, lemon, vinegar, even Coca-Cola. 
  • Use less fat. Choosing cooking options that use less fat mean less oil enters the air.  You could boil, roast or grill.  Trim the fat off your meat before cooking.  Anthony St. Clair offers many tips on how to reduce your cooking fat usage. 


The easiest option of all …

The easiest place to deal with kitchen grease is in the filter.  If the aerosols get trapped as soon as they enter the air, they cannot float around and be a pest anywhere else. 

You need to get a better extraction system. 

Firstly, check your extraction system is extracting at least 1.5m of air every second.  If it is not, you may need to repair your fan, or replace it. 

Next, invest in Shepherd Filters.  If you have grease problems, these will honestly change your life.  We were not told to sell these filters; we discovered how good they were ourselves and then begged to sell them.  Shepherd Filters are disposable (or compostable, if you are into that) as they are made 100% from natural sheep’s wool.  Your current grease filters are probably capturing up to 40% – at the most – of the aerosol army that is floating around.  If you install Shepherd Filters, you can expect 98% of that army to be captured in the wool. 

In fact, when installed in a fried chicken fast-food chain, Shepherd Filters captured nearly 2kgs of grease every week.  That is more than 100kgs per year!  If using standard filters, the staff in this kitchen would have had to deal with at least 60kgs of grease every year.  Instead, all they had to do was spend 60 seconds, 15 times a week replacing full filters with fresh ones.  (This kitchen used 15 filters every week as they produced an excessive amount of grease – we would not expect many kitchens to go through this many.)


If you genuinely want to eliminate that filthy grease coating that drowns your kitchen, Shepherd Filters are the solution for you. 

However, if you don’t want to take 60 seconds each time a filter needs changing, you may need to choose one of the previous options to deal with your grease.

All the best.
