Our pipe cleaners are available in a variety of diameters, lengths, shapes, and materials with soft and hard cleaning properties. Cotton and fleece are particularly well suited for gentle cleaning given the soft nature of these materials. Nylon bristles, on the other hand, are better for tough-to-remove residues due to their hardness. Depending on the application requirements, the lengths vary from 20 cm to up to 10 m on a reel or as a set with a dispenser.
