"Weathering" paving slabs

[wristpin]

I have an area at the back of the garage paved with "council quality" paving slabs that are a nice grey colour. Needed to extend it but have been unable to find any reclaimed slabs so have had to settle for new which are very white.
Any suggestions for treating them to dull them down a bit . Suggestions so far have been saving used tea bags and coffee grounds in a bucket with some water and applying the resulting liquid or, a dilute solution of water based fence preservative.
Just need something to speed up the ageing process - any ideas?

My dad used to do alot of stone carving, stadle stones and the like, and sell them on. He used out of date natural yoghurt.

how about power wash the old ones to get them close to the new ones

Pressure washed all of ours that I've put down over the course of the year. They're all about the same now.

Thanks for the suggestions. I don't think that the power wash will work as the old one seem to be grey right the way through, not just on the surface, however I will investigate the yoghurt and horse poo option.

rub the top of them with a carborundum block and they will soon weather

I've been told that a mixture of milk or yoghurt and cow poo, sloppier the better, to age new stone roofs so they blend with the old bits quicker. The hard bit is getting the cow onto the roof.

Natural yoghurt and keep them damp.

Why not turn the original pavers over, ad then power-wash them? I bet they come up like new and match the new ones almost exactly.
