Swarfega Duck Oil, £6.75 for 500ml
Time used: Three months

What’s good: I recently stripped down the front end on my BMW R100R, and many of the nuts and bolts had rusted and seized. The solution is simple: give them a good squirt of Duck Oil, leave for a while (about as long as it takes to make and drink a cup of tea) while the product penetrates deep between the two surfaces.
Once you’ve finished your cuppa you’ll be able to undo your bolts with relative ease. It is also good as preventative medicine – a quick squirt on nuts and bolts before doing them up helps form a protective seal against rust.
It also works on electrics, helping waterproof them. A great all-rounder in any workshop.

What’s not: What ever you use your Duck Oil for, do not do what my friend’s elderly father did.
Whilst cooking a Sunday morning fry up he gave a healthy squirt of duck oil into the now warming frying pan; during cooking it smoked somewhat, but it was only when he took his first mouthful he discovered it was definitely not for cooking. Never confuse Duck Oil with goose fat! A true story, I kid you not.
