Here’s the description on American amazon. I think it does collect dirt, but they say it doesn’t. Anyways, it is a very good product. One can lasts a very long time. Two thumbs up for keeping exposed metal from rusting in Ohio winter road conditions for years.
“ On a seafaring yacht, a dusty ATV, or a shower door, T-9 has you covered. Boeshield T-9 endures muddy bike trails, rain-soaked back roads, and salted highways. It withstands farmer’s fields, offshore oil rigs, and carpenter's workshops. For everyone from firefighters and road crews to cyclists and sailors, Boeshield T-9 is the proven solution. T-9 attacks existing corrosion, loosens rusty parts, and flushes out old lubricants. It is also extremely useful for drying wet parts, electrical motors and circuits, ignitions, and connectors. Apply T-9 and wipe off the excess for immediate use. T-9 dries to a waxy, waterproof finish without leaving a sticky film to attract dirt, dust, or mud. T-9 stays liquid long enough to permeate metal crevices and seep deep inside assembled components to leave a durable protective coating as well as lubricating and protecting-all without dismantling your equipment. Apply T-9 to any metal surface and let it dry. One simple step gives you a thin, penetrating film of durable, waterproof protection and lubrication that endures, months after month or mile after mile. T-9 dries to a clean, waxy, waterproof film that won't wash off in rain, puddles, or mud. You can rinse away sand, dust and grime with water, while leaving the lubricant intact. T-9 will not harm paint, plastic, rubber, fiberglass, or vinyl. It can be used on engines, wiring, and belts. T-9 is nonconductive and will not cause short circuits, so it's also safe to use on electronics. Use solvent or any emulsifying cleaner to easily remove T-9, or simply respray and allow T-9 to dissolve itself before wiping it off.”
