Yes, you can! However, experts suggest you should power wash only if you have thorough knowledge about bike parts. A reckless power wash can damage your bike or a few parts of it. Even if you do not see damage instantly, you will realise it over time. One such instance is when water pushes into the bearings, they age quickly. The Bike pressure washer comes with different techniques to handle different parts. First of all, you should avoid side spraying. You can blast down from above, up from below, and from the front and back, avoiding blasting into jockey wheels, bottom brackets, pedals, and hub bearings. It might be slightly difficult for first-timers. So, read the manual thoroughly or watch some videos online to get the hang of the whole process.
