After using it, you can get on a clean bicycle with a nice pine scent - a good way to start an epic ride. It is also ideal for E-Bikes since there is no need to rinse it away after cleaning.There are times when you are in a hurry and a quick cleaning is sufficient, or - especially for e-bikes - you want to limit the use of water close to electrical contacts. For these situations of moderate dirt, Allpine Light and a rag are enough to clean the bike, without the need to rinse with water.Use Without Rinsing: Spray Allpine Light on a clean rag and wipe the entire frame After cleaning, the surface will be shiny, with an anti-water and antistatic effect As it does not contain silicone, it avoids that annoying sticky effect which is a real dust magnet. The surface thus treated also facilitates the flow of water Note: Allpine Light does not remove the lubricant from the chain, so it is not necessary to relubricate it after such a cleaning When the going gets tough, it doesn't hold back If the bike is very dirty and / or muddy, you have to perform a serious cleaningUse With Rinsing: Generously spray Allpine Light all over the bike Wait a few minutes to let the product act Rinse with plenty of water. A sponge or brush is recommended for an optimal result Dry with a clean cloth.
