Proper Approach to Bleaching Rock: Tips Needed

[db366]

You could always put it in a tub with a bottle of prime just in case it still has some bleach in them.

Chlorine needs to be completely dry before it evaporates, I believe. I would let it dry first.

Then, I would rinse it in Hydrogen Peroxide at 3% for at least five minutes...then rinse with water.

I put all my rock in a 100g rubber maid(just barely fit) and let it soak in a 10% bleach bath overnight.

I then filled and drained the tub with fresh water twice.

Then I did a 4 hour bath in 3% acid, followed by two more rinses.

Last I let the rocks dry out back for a day, then pressure washed them to get anything loose off, and let it dry again.

If anything bad is still on those rocks Ill be amazed.
