DeoxIT D-Series contact/connector treatment, dissolves oxides and sulfides that form on metal surfaces. This restores the contacts integrity and leaves a thin microscopic layer that protects the metal. Special additives improve conductivity and prevent dissolved oxides from re-attaching, keeping them in suspension and allowing them to be easily dispersed by the mechanical action of the contact.Kit Includes:DeoxIT D25L-25C, 25 mL bottleDeoxIT Gold GXMD-2DB, Brush ApplicatorB-SS116, stainless steel precision cleaning brush, 1/16 dia., 4 overall length, loop endLint-free swabs, brushes, clothsSpecifications:Display box (8.0 x 5.0 x 1.5)
