Dry Pikani bleach than acid bath

[Easto]

I have a lot of stuff on the rocks, not idea what any of it is.

I'll grab 1 or 2 rocks that have the most discolouration and take a few shots. See how they look at each stage.

Ok, this is huge. Not too sure how to resize on my phone.

But this is probably the dirtiest rock of the bunch. Some dark brown, some red stuff, etc.

After a few hours the rock has lightened up quite a bit

I rinsed the rocks then did the acid.

I'm not sure how long I was supposed to leave the rocks in there. I probably added the baking soda too early.

A lot of crap came off the rocks, but there is still a good amount of dark brown and a few red spots still

I left them in the acid for about 2-3 hrs, until the bubbles had all stopped and popped. Then added the baking soda and let that sit for another hour just to make sure.



Once it was all done there were still a few brown areas on the pukani.

When I did it, I poured acid in, waited until the reaction was over, then poured more in until the reaction stopped. Then I let it sit for a couple hours. Then did baking soda.
