Headlamp refurb for around £1

Don't all scream and shout that i am mad, woop woop ha ha, i saw this on you tube so thought i would give it a go.
I spent 10 to 15 mins vigorously rubbing my headlamp lenses with toothpaste, yep, toothpaste. Here's how.
First clean the headlamps and dry, then cover headlamp lens with toothpaste and with a clean cloth rub using firm pressure, if the toothpaste dries out just sprinkle a little water on and carry on. You have to be patient and keep going and you may have to repeat the procedure a few times, paid off for me, see the pics noting the tops of the lenses.
