Mini Maintenance Kits for fertilizer and chemical injectors include wear parts, Dosa-Klean, and a new product – Dosa-Lube, and were created for 11, 14, 20, 40, and 100 GPM injectors. The company says that soaking injector parts in Dosa-Klean for 24 to 48 hours cleans rust, mineral deposits and calcifications without scrubbing. Dosa-Lube, a packet of silicone, is designed to lubricate static seals and o-rings while you are changing the wear parts.
