GT85 is a UK-established maintenance spray brand that sits within the WD-40 Company portfolio, following WD-40’s acquisition of GT85 Limited in September 2014. Today, GT85 is positioned as a professional-strength solution for everyday mechanical upkeep across garages and workshops, supporting common tasks such as freeing stiff mechanisms, reducing friction on moving parts, and leaving a protective finish as part of regular service routines.  At product level, GT85 is marketed as a “clean, lube and protect” spray with water-displacing properties, suitable for a wide range of applications including vehicle and bike components, tools, and general workshop equipment. This makes it a practical choice for maintenance teams and motorists looking for a versatile lubricant/protectant for hinges, linkages, fasteners, cables and general mechanical assemblies where a light spray lubricant is appropriate.  Note on PTFE: some GT85 cans in the market are labelled “with PTFE,” while newer production has been communicated as PTFE-free (with older PTFE stock identifiable by specific badging on the can). If you are listing a PTFE variant, it is best to reflect what is printed on your exact unit/label.
