- You can re-use your old Muc-Off bottle or our aluminium Bottle for Life and clean with a guilt-free conscience. It also works with our pressure washer to create an awesome foam for the fastest clean possible! What’s even cooler is that if you want to be the ultimate eco warrior, you can even use rainwater to re-fill your bottle and mix with your PUNK Powder sachet! As well as being eco-friendly you can massively reduce the amount of processed tap water you are using to clean your bike. Any type of water from the water network, rainwater or natural water can be used as long as it is clean. This means when you’re out on your next biking adventure in the middle of nowhere and you want to top up and clean your bike you’ll have no issue doing so from a stream or river. Take this one step further and for a completely plastic free bike wash you could use our Silicone Scrubber gloves and a metal or wooden wash bucket. Simply pour two sachets of PUNK Powder into a bucket of water and mix up ready to clean your two wheeled pride and joy.
