If you are cleaning up spills outside, you want your absorbents to become fully saturated with whatever you are cleaning up, not rain water. MEI oil-only absorbent pads are your best option for outdoor spill control & prevention. They repel water leaving their full absorbency for oil-based liquids. The grade of pad that you choose is dependent on your application and refers to the durability of the pad. We recommend a "light" pad for less rugged applications such as wiping down shelving and counter tops. "Medium" pads are the most popular grade of absorbent because of their balance of durability and price-point; they can handle most applications. "Heavy" pads are reserved for tough and rugged applications where there is a chance the pad could get torn up such as on rough surfaces or cleaning sharp tools.
 
General Absorbents are a "go-to" for those that need a reliable sorbent to tick all the boxes as far as compliance goes. A great all around solution that'll do most tasks well. Recommended for basic spill control & prevention tasks. These sorbents have minimal lint on them an are run through a bonder once to increase strength and durability.
 
 OIL-ONLY ABSORBS:  Motor oil, hydraulic and brake fluids, gasoline, turpentine, diesel fuel, aircraft fuels, transmission fluids, cooking oil, and other oil-based liquids including paint.
