Regular cleaning of grease traps is important to prevent blockages for restaurant businesses. If a grease trap is not properly maintained over time, grease can build up and cause plumbing issues. For do-it-yourself cleaning, one needs protective gear like masks, gloves, and coveralls, as well as tools like scrapers, crowbars, and vacuums. It is important to contain grease during cleaning and dispose of it properly. Professional help may be necessary for larger traps.
