We all want to keep our bikes clean. Not only is it the best way to pride and joy looking its best but it’s an important part of its maintenance schedule and a vital way to ensure it’s performing to its best ability, too. But it’s important to look after the environment too, so it’s good to purchase eco-friendly motorcycle cleaners.

Many traditional cleaning products, by being solvent or acid-based, can be potentially disastrous here, not just to drains and the water systems, but to the atmosphere and in terms of packaging as well.

Which is where the new breed of ‘eco-friendly’ automotive cleaning products, many of them specifically designed for use on motorcycles, come in.

These are often alkaline or water-based, so pose no threat to the environment, are available with refills, so have potentially less waste packaging and are often designed to tackle specific cleaning tasks on your bike.
