Fenwicks FS-1 - No acids or solvents, ideal for all bikes

1 x Litre makes 11 litres of bike wash

In 1996 we created our first bike cleaner concentrate called 'Hog Wash' If any of you have a bottle drop us a line. This was way ahead of the curve as it didn't take off due to the already mixed, ready to use bike cleaners out there. Relaunched in 2003 as FS-1 because of our belief in giving you value for money, the demand for FS-1 Bike Cleaner Concentrate increases by the day as there are now lesser concentrates on the market.

This is because 1 litre of FS-1 can make up to 11 litres of ready to use bike cleaner, making it £0.91 per litre, a no-brainer really. We even have a special fill line on our FS-10 bottles at the bottom to help you out creating the perfect bike wash every time.
Like no other company we produce such highly concentrated cleaners using a complex blend of high quality liquid raw materials (others use cheaper powdered raw materials, which can leave a powdery residue when dry) FS-1 Bike Cleaner Concentrate cleans deeply and easily to leave exceptionally clean contaminant-free surfaces. Safe for you, your bike and the environment. Free from caustics, metasilicates, abrasives and silicone. Safe for use on all bike parts including carbon fibre, disc brakes, delicate anodized parts, etc. Plus it's strong enough to be a great degreaser.
