Hi-Vis yellow w/caution STF warning spunbond-fine fiber composite mats are great dual-purpose sorbents. The spunbond side is abrasion-resistant, which is great for foot traffic or heavy-duty wiping applications. The fine fiber side is great for gripping smooth surfaces (like cement) and for removing the sheen from slick surfaces. They absorb most non-aggressive fluids, which includes oil (hydrocarbon-based fluids), water, glycols, etc. A perforation helps reduce waste.
