How to Clean Grease on Any Surface

The Ultimate Guide to Cleaning Grease

Grease can be one of the most frustrating things to clean up; it tends to stick to just about anything it touches. It can even be spread in vapor, leaving small droplets all around your kitchen that you might not notice until the next time you cook.

It is especially important to be able to handle grease cleanup in commercial kitchens. With the high volume of cooking, grease can easily find its way around the space, becoming potentially hazardous for employee falls or grease fires.

Carbonized grease and grease residue can be red flags for inspectors, too, as there are quite a few negative effects it can have on a kitchen. Uncleaned grease can lead to sanitation issues and odors while attracting pests, the bane of those trying to survive restaurant health inspections.

This guide should help you tackle just about any form of grease, prevent spills, and clean yourself up after coming into contact with grease.

How to Remove Grease Stains in a Commercial Kitchen

Grease can build up quickly, especially if it isn’t being cleaned regularly. Many commercial kitchen owners overlook the importance of having the right tools for their restaurants, and some even cut corners, explicitly disobeying FDA guidelines.

It is vital to both the employer and employees to have the knowledge and equipment to safely maintain a commercial kitchen. Obtaining the right cleaning products is a great way to start. Making sure that cross-contamination is eliminated, the correct agents are used at each stage, and proper procedures are followed should take priority in the kitchen.

Degreasing Kitchen Walls, Floors, & Ceiling

Over time, grease can find its way to just about every corner of your kitchen. The longer that you wait to remove it, the harder it can be to get clean. The process used to clean is fairly simple, yet can appear daunting as it can be time-consuming. Regular degreasing throughout the day can make end-of-shift deep cleaning much simpler.

The first thing you need to understand is the surface you are cleaning, and what cleaner(s) you need to use to get the job done.

  • Smaller areas and quick touchups can usually be handled by using a cleaning and degreasing wipe.
  • If your walls are painted it would be advisable to start the cleaning process by using the gentlest method available, such as using plain water and a sponge before moving on to a chemical cleaner. Walls and ceilings may require a different solution, as not all cleaners are going to be a safe bet for your painted surfaces. Check the label on any product you are using for manufacturer guidelines, and consider doing a spot-test in a less-visible area before using a new cleaner on sensitive surfaces.
  • Consider wearing Personal Protective Equipment (PPE), depending on your degreasing chemical of choice.

The process used to clean grease is relatively simple:

  • Start by dusting/sweeping the surface you are working with.
  • Prepare a solution of water and a chemical mixture. A ready-to-use product or degreasing wipe can eliminate the need for mixing chemicals.
  • Then, begin blotting the grease away using a dry wipe before using the prepared solution. If needed, you can use warm water to soften splatters and stains so that wiping will become easier.
  • Using a circular motion, try to work in sections, and wipe the area dry before moving on.

Stains caused by grease may take a little more effort to remove, but the process will be similar. Continue to wipe the grease away until it all comes off. If you are working on a ceiling, try not to over-douse your sponge. Rather than using a ladder repeatedly, you can use a dedicated mop to clean ceilings and the upper areas of walls.

Degreasing Stoves and Counters

Frequent cleaning of your stove and countertops is usually recommended, but it’s not always that ideal. Keeping wipes nearby and accessible is a great way to promote prompt and regular cleaning.

Stoves are known for being notoriously hard to clean, though they typically can handle chemical cleaners better than other surfaces. Remove your heating coils and drip pans after clearing debris away, then begin by coating the surface in a cleaning solution. Most chemical cleaners work better if you give them time to penetrate the surface of the grease; this is especially important if the grease is burnt or carbonized on the surface. Once the solution has set, you can begin wiping away the grease. A heavy duty wipe can also be effective at scrubbing grease away.

When cleaning countertops it is especially important to know what type of counter you are dealing with. Each type of countertop has its own cleaning and maintenance needs, and must be treated accordingly. Using an abrasive sponge might work well on granite, but if you have marble countertops, you run the risk of scratching the surface. Pay close attention to the ingredients in the cleaner you are using, as some surfaces don’t react well to certain chemicals.

Degreasing Handheld Kitchen Appliances

Many kitchen appliances that are commonly used are going to come into contact with food. While it is generally safe to use chemical cleaners on these appliances, you also run the risk of those chemicals sticking to the surfaces of them as well. After cleaning, be sure to rinse and sanitize  appliances prior to use on food.

Cleaning Yourself Up After a Grease Spill or Splash

It is all too common to come into contact with grease during cooking or cleaning. No matter how you get it on you, you will want to remove it.

Treating Grease Burns

Grease burns are one of the most painful ways to come into contact with grease. Depending on the severity of the burn, you may need to seek immediate medical attention.

After being burned by grease, you should run the burn area under cool (not cold) tap water to alleviate residual heat, so long as an open blister has not formed. Use a gentle stream of water, as a stronger stream may cause further damage to the skin. Remove any jewelry and tight-fitting clothing after rinsing as the affected area may start to swell.

A blister may form, but it is important not to pop it, as bacteria can enter through the wound. Loosely wrap the burn making sure no loose lint or substances come into contact with the burn site. If an open blister forms, avoid running cool water over the blister and apply a sterile dry bandage to the area.

How to Get Grease Out of Clothes

If you need to get grease out of your clothing, there are a few methods you can use. You can pour dish soap or detergent onto the stain, rub it with a toothbrush, and then run it through a normal washer cycle.

If soap and detergent didn’t do the trick, you can try using WD-40, baking soda, and soap. Start by spraying a light amount of WD-40 onto the stain, then cover it with baking soda and scrub. The grease should mix with the WD-40 and bind to the baking soda, though multiple applications may be needed. Once the grease is removed, rub liquid soap or detergent onto the stain before sending it through the wash. Grease will become more difficult to remove the longer it has set, and the more times the clothing has been washed with the grease still on it.

How to Get Grease off Your Hands

Removing grease from your hands is generally much easier than removing it from clothing or walls. Just know that you will most likely need more than water to effectively remove it. You can wash your hands with soap normally, but sometimes this won’t remove all of the grease on your skin. You can try to add a little sugar to the soap to increase abrasion. WD-40, citrus cleaners, and coffee can all be used with a little elbow grease.

Using stronger chemicals may do more damage to your hands than the grease, so make sure to research the chemicals in the cleaner you intend to use on your skin. Hand sanitizing and antibacterial wipes may help in removing grease from your skin, and are safe to use regularly.

Best Practices to Minimize Grease Spills

The easiest way to minimize grease spills is to make sure that they don’t occur in the first place. Grease is a foodservice by-product that kitchens must constantly manage, and its accumulation in areas is virtually inevitable. Splatters and stains can be cleaned fairly easily, but spills can be far more tedious to deal with. Preventing these spills can reduce the amount of waste in prep and serving areas, help prevent employees from slipping, and reduce the probability of sanitation issues.

Storing Grease

Typically a vendor will supply a container for grease, and the size of the container should correlate to how much grease is produced in the kitchen daily. If the grease trap from one or two fryers is being dumped weekly in a lower volume kitchen, then a more modest container may be enough. If the kitchen is operating in a substantial volume, it might be a better idea to use a higher capacity container.

In any event, coordinate with your restaurant’s vendor to ensure you have the right sized containers and waste removal schedule. Always plan to empty the container before it is full to help minimize the risk of a spill. Lastly, these containers should be stored in areas favorable to streamlining the transfer of grease, as well as the disposal of the container’s contents.

Proper Steps to Dispose of Grease

Steps and considerations for responsible disposal of spent or used grease in a restaurant include:

  • Contact a vendor/grease recycling company.
  • Obtain a container, typically provided by the vendor.
  • Wear protection such as gloves, mask, and coveralls.
  • Check grease temperature, and make sure the fryer is off.
  • Remove the lid from the container.
  • Transfer grease from trap into container.
  • Reseal the container.

It is also important to keep drains clean, as this will prevent clogging and reduce the chance that vermin such as flies will be in the kitchen.

Grease buildup is a sanitary problem in restaurant kitchens, and most states mandate that grease traps be cleaned regularly. If left uncleaned, it carbonizes, accumulates substances, and can become a breeding ground for bacteria, among other sanitary issues. The more proactive you are about cleaning grease, the easier the process will be.
