In a hectic commercial kitchen, there’s almost nothing worse than a severe drain clog. Not only do clogs look and smell horrific, but they also impede normal daily operations. Staff cannot wash dishes or keep their workspaces clean, which ultimately affects the business’s bottom line. Though kitchen drain clogs are probably the most commercial drain problem, they can be prevented with a few simple, easily implemented measures which our Drain Blaster Bill’s team has outlined below.


Place Food Waste in the Trash, Not in the Sink

In the middle of a hectic dinner rush, it’s all too easy to scrape food waste from diners’ dishes straight into the sink — but doing so is a perfect recipe for drain clogs. Most food scraps contain some type of starch or oil, both of which can stick to the interior of the drain and accumulate over time.


As dishwashers continue to scrape food into the sink, incoming food scraps can get caught up in that sticky mess, further contributing to the formation of a drain blockage. Eventually, the sludgy grime that accumulates along the interior of the pipe will slow water drainage. And in a worst-case scenario, the food buildup will completely block the pipe.


To avoid clogged sink drains, make sure you educate your staff on the importance of tossing waste into the trash instead of rinsing it down the drain. Though the change may require a bit of an adjustment period to stick, your kitchen sink drains will remain far cleaner as a result.


Use Absorbent Cleaning Materials to Wipe Grease Off Dishes

Most restaurant meals contain a decent amount of fat, which can leave an oily residue on diners’ dishes. Though a small amount of grease or oil may seem like a non-issue, a high-volume commercial kitchen washes hundreds, if not thousands, of dishes each day. And with that many dishes running through the wash, even a small amount of greasy residue on each one can eventually result in a drain problem.


Good news: There’s a simple way to cut down on the accumulation of oily residue inside your kitchen sink. Simply ask your staff to use absorbent cleaning cloths to wipe oils, grease, and fat from dishes prior to washing them.


Never Pour Fatty or Oily Substances Down the Drain

Most restaurant employees are well aware of the fact that oils and fats never belong in a drain. Rather, staff should place used fats and oils in disposable containers after allowing them to cool down. Those containers can be disposed of safely in the trash. Just to make doubly sure excess greasy cooking ingredients don’t find their way into your pipes, it may also be a good idea to post signage outlining proper disposal of fats and oils. 


Run Hot Water Down the Drain Daily

No matter how diligent you are about properly disposing of food waste and greasy ingredients, you simply cannot get rid of every bit of grease on each dish. You have to assume that each time a dish is washed, a small amount of oil and fat will enter the sink drain. So what can you do about it?


As you’re closing and cleaning up for the night, run very hot water down the drain for a couple of minutes. The hot water will help liquefy and wash away any residue that adhered to the interior of the drain throughout the day.


Maintain Grease Traps

If your commercial kitchen has a grease trap, make sure you clean and maintain it regularly! Having a grease trap doesn’t automatically protect your kitchen from drain clogs — but having a CLEAN, properly maintained grease trap goes a long way toward keeping your drains clear. To clean your grease trap, perform the following steps:


1.      Take the lid of the grease trap, being careful to remove it gently, so you don’t damage any gaskets.

2.      Insert a ruler into the trap to gauge the amount of accumulated grease. Jot down the number of inches of grease in the trap, so you can complete the required EPA reports.

3.      Use a bucket or pump to remove the water from the trap.

4.      When you’ve removed all the water, begin scooping grease out of the trap with a shovel, scooper, or bucket.

5.      Thoroughly scrape the sides, bottom, and lid of the trap to remove remaining grease.

6.      Scrub the interior of the trap thoroughly and flush the screens.

7.      Pour the necessary amount of water back into the trap, reinstall any parts you had to remove, and replace the lid.
