You'll need the following before you begin:
Large Trash Can;
2 or 3 trash can liners (garbage bags);
Oil dry (purchase at an auto supply store);
Proper tools to open trap;
Tools for removing contents (scoop and scraper);
Prepare your work area;
Put the trash can liners into the trash can;
Add some oil dry (this will soak up the water and liquid and make transportation of the waste cleaner and safer);
Remove the lid;
Observe the manner in which the internal parts are installed because you'll have to reinstall it properly when you finish cleaning the trap.
missing or mal-aligned internal parts will cause discharges that are in violation of the allowable limits of the Industrial Pretreatment Ordinance.
Examine the gasket for damage - never use tube silicone as a gasket.
If the gasket is falling into the trap, clean and reattach it to the trap;
Begin dipping (or vacuuming) the waste from the trap.
Remove all contents until unit is empty.
No need to use degreasers or soap and water - no one is eating out of this trap.
Make sure the trap has been properly reassembled (all internal parts are in place).
Tie up the bag of waste (that has the oil dry soaking up the liquid) and place in the garbage (solid waste) dumpster.
It's as EASY as that....
