Efficiency is affected by buildup of settled solids, sludge, or oils. Inspect the plates in each chamber once a week. Degreasers and detergents because they can emulsify or dissolve oil so it won't float to the surface - and then can't be removed by the separator. A Oil and sludge can clog baffles or plates and pass through to the sewer - divert it away from your separator. Another way is to place absorbent pads or socks in the inlet chamber, then wring out into a collection drum and reuse them.
Sludges are difficult to clean out and disposal is expensive.
A catch basin, installed ahead of the separator, will trap solids. Shovel them into a collection drum before they reach the separator and have the material tested to determine if it's a hazardous waste.
