Otis Bio CLP is a biodegradable cleaner, lubricant, and protectant for firearms — sold in 1-gallon bulk size for armorers and high-volume shooters.
Otis Technology manufactures Bio CLP in Lyons Falls, New York. The biodegradable formula avoids the petroleum-based concerns of older CLPs while delivering the same three functions: cleaning, lubrication, and corrosion protection.
Use the 1-gallon Bio CLP for armory restocking, range maintenance, and high-volume shooters who go through quart bottles too fast. Refills smaller bottles for years of use.
