I have some large pieces of petrified wood (eastern wyo). They range in size from 20" diameter x 36" to 36" diamter x 48" tall. There appears to be lots of color showing, in fact one piece has a large center piece that is reddish color like an extremely large agate.
How can I really clean the pieces and bring out the color--water and scrubbing with a car brush has only given me a peek of their character and the rings.
