For businesses in South Carolina, it’s not uncommon for commercial kitchens to handle large amounts of cooking grease. If your staff isn’t following proper practices to keep grease out of the sink, it can cause serious plumbing problems.


Clogs can halt your operations, lead to other plumbing issues and be costly to fix. To help prevent these problems, here are eight best practices for managing grease and keeping it out of your sink drains.


#1 Install Sink Strainers


Using sink strainers in your kitchen is a simple and cost-effective way to prevent grease and food debris from clogging your plumbing. Strainers catch grease and food particles before they enter the pipes, reducing the risk of blockages over time. To remain effective, strainers should be cleaned and emptied regularly, ensuring they continue to protect your drains and keep your kitchen running smoothly.


#2 Recycle Used Cooking Oil


One way to prevent grease from entering the drain is by recycling. Instead of pouring oil down the drain, collect it for biofuel companies. Once your grease bin is full, the company will pick it up. The oil will then be recycled to create biofuel or other products. This practice keeps your pipes clear, reduces environmental waste and helps lower disposal costs.


#3 Scrape Dishes Before Washing


Scraping dishes before washing is one easy way to prevent grease and food particles from entering your drains. By removing leftover food and oily residues first, you stop grease from accumulating in your pipes, which helps prevent clogs and slow drainage. This practice also helps your sinks and dishwashing equipment operate more efficiently, reducing the likelihood of breakdowns.


#4 Flush Your Drains With Hot Water


A simple yet effective way to prevent grease from building up is by flushing your drain regularly. Hot water helps to dislodge lingering food debris and oil, allowing them to flow through the pipes. Incorporating this practice into your routine maintenance is a cost-effective way to reduce the risk of clothes, ensuring your kitchen stays clean and operational.


#5 Educate Employees About Best Practices


When it comes to tackling grease, education is key. Once your staff understands how to properly handle grease, the risk of clogs, plumbing damage and costly repairs is greatly reduced. Regular training ensures everyone is on the same page and reinforces habits that protect your plumbing system, maintain kitchen hygiene and keep operations running smoothly.


#6 Maintain Your Grease Traps


Keeping your grease traps clean is one of the most important ways to prevent grease from clogging your sinks. These traps capture fats, oils and grease before they enter your plumbing, helping to avoid costly backups and blockages. Even with routine emptying, grease can still build up, especially in kitchens that are used frequently. 

Having your grease traps professionally cleaned ensures they function effectively, reducing the risk of unpleasant odors, pest infestations and potential health code violations. Staying on top of grease trap maintenance protects both your kitchen operations and your plumbing system.


#7 Get Your Drains Professionally Cleaned


Having your drains professionally cleaned is a crucial step in maintaining your kitchen drains. Even with best practices in place, grease and debris can accumulate over time. A thorough cleaning can get rid of scum buildup and stubborn food residue. Regular cleanings not only prevent backups but also extend the lifespan of your plumbing. 


#8 Cover Your Grease Containers


Covering your grease containers helps prevent grease from getting into floor drains. If a container is accidentally dropped, the cover reduces the chance of a spill, keeping your kitchen safer and cleaner. Covers can also be used outdoors to keep pests away and help maintain a clean space.
