How do you clean and brighten Texas Holey Rock?

You can clean honeycomb limestone with a pressure washer or by hand with a toothbrush. The pressure washer is quicker and more lazy and could damage the rocks if you aren't careful though.

I believe to get them really white, most places that sell them power wash them and then soak in a bleach/water solution.

If you do that make sure you rinse them very very well, and then I'd probably double-dose dechlorinator when you add the rock to your tank.
