If you’ve ever stepped into a professional bike shop or a busy motor garage, you’ve likely caught that distinctive lavender scent. That’s the smell of GT85, the "black and red" can that has become synonymous with keeping things moving.
While some might mistake it for just another lubricant, GT85 is a versatile 3-in-1 formula designed to lube, clean, and protect.
1. The Power of Water Displacement
One of GT85’s primary strengths is its ability to flush out moisture. After a wet ride or a heavy jet wash, spraying GT85 on your derailleurs, chainrings, and moving parts helps prevent the "internal" rust that kills components. It’s particularly effective for electrical circuits and power tools, where it cleans residue and prevents moisture-related shorts.
2. A Superior Finish
Unlike heavier oils that leave a sticky residue, GT85 is known for its ability to bring a shine to your equipment.
- For Bikes & Cars:Â It can be used on paintwork and plastics to remove tar spots and leave a protective, non-sticky layer.
- For Tools:Â A quick wipe with GT85 keeps your hand tools rust-free and looking brand new, even if they've been sitting in a damp shed.
3. Lubrication and Penetration
While there is a long-standing debate about using it as a primary chain lube—some pros swear by it for a quick "one and done" fix, while others prefer dedicated oils—there is no denying its ability to loosen seized bolts and lubricate stiff hinges. It penetrates tight spaces to free up rusted fixings that other sprays might miss.
4. What Not to Do
As versatile as it is, there is one golden rule:Â keep it away from your braking surfaces. Getting GT85 on your brake pads or rims can lead to a dangerous loss of stopping power. Always use a clean rag to apply it near sensitive areas.
The Verdict
Whether you're fixing a squeaky door hinge at home or prepping your road bike for a 100-mile ride, GT85 is the versatile, affordable, and effective choice that belongs on every shelf.
