Best Buy UV Light
Jim Deardorff, Chillicothe, Mo.: “Handheld black lights like the high-intensity uvBeast light are a best buy for anyone concerned about leaks (www.uvbeast.com). Hydraulic and engine oil, as well as other fluids like transmission oil and antifreeze, all fluoresce under a black light. If there’s oil in stress cracks, it shows up as well. The black light is also good for checking caulk and sealant effectiveness.
    “I use mine when repainting equipment. I use a soy-based pre-cleaner that produces a natural bioluminescence. However, I can also mix in a fluorescing additive to make the effect brighter. If dirt or grease remains, it stands out under the UV light.
    “If the surface has truly been cleaned, it won’t rust for hundreds of hours, even without fresh paint. I recommend my farmer customers apply Permanon (another best buy) immediately after cleaning to extend cleaning performance (www.permanonfinishes.com; ph 800-288-3346). It also reduces future cleaning expenses.
    “Our local elevator uses black lights to check for aflatoxin. With the uvBeast, you can go out in daylight and check. It’s also good for checking for mouse and pet urine.
     “The uvBeast lights come in a range of models. I use the 365NM UVx4. It has a high-performance filter that blocks out visible light and allows the UV light to pass through. It costs about $79 and is well worth it.”
