You can mix it with clear water to create your own cleaner. 250 ml of concentrate and 750 ml of water yield 1 liter of bike cleaner. You can find the dimensions on the side of your 1-liter bike cleaner bottle. For very dirty chains and derailleurs, you can also apply the concentrate directly. Let it sit for 30 seconds and then rinse with clear water. Reusing is better for the environment, and with the concentrate, you can save 89% on packaging when using the 500 ml pouch. If you're wondering which parts of your bike the concentrate can be used on: it is safe to apply on frames, forks, headsets, suspension elements, handlebars, grips, saddles, bearings, rims, spokes, hubs, disc brakes, suspension components, chains, cogs, drivetrains, aluminum, steel, anodized metal, all types of paint, chrome, carbon, plastic, stickers, and rubber seals.
