Toothpaste.

[Alan Frame]

My seatpost had been slipping recently, however much I tightened the clamp.

I can confirm that a smear of toothpaste does indeed seem to have done the trick !

This is on an alloy seatpost and steel frame.

Darn sight cheaper than carbon assembly paste.

[Alan Frame]

At this rate I shall even consider using it on my teeth !

Removes crayon marks on painted walls too and removes scratches on DVD'd and CD's apparently

And can be used to refresh / replace grouting.
Not the stripey sort, obviously. Unless you have stripey grouting.
