Muc-Off’s MO-94 is their premium multi-purpose spray that protects your bike in a bunch of ways. MO-40 lubricates parts, stops rust, and adds a long-lasting protective film. We have individual products that raise the bar a bit. But if you want just one lubricant and protectant on your shelf then MO-94 should be it. Hint - think of this as WD-40 but with more protectants and without the greasy after layer. And without the smell !
