There’s a very good use for it and it’s not what you’re thinking! It’s ideal for keeping electrical connections moisture free. My right headlight has been failing and the last one I put in only lasted two months. At fourteen quid a go I thought I’d better try a bit of preventative care.

When I removed the headlight unit there was a fair bit of corrosion – greeny, old copper looking colour – on the pins of the bulb and in the connection. It’s a sign moisture is getting in which isn’t a good thing. To get a good connection again, sand down back to the metal to get rid of the corrosion and apply a liberal dollop of Vaseline. Vaseline repels moisture keeping the connection clean and improves conductivity. It’s useful for any electrical components especially on those cars that have poor electrical connections which can cause intermittent failures in lights, arcing in bulb units and burnt plastic mounts. You’ll quite often see white grease in bulb units - it’s a common trick of the motor trade to improve and maintain electrical connections.

So whenever your electrics are causing problems, slap on some Vaseline!

I would normally you ask for any other ideas at this point but this time I don’t think I will
