Driftwood (am i doing it right?)

[Mindelo]

Hello,
I'm having my first experience with driftwood, so i need some advice from you guys:
couple months ago i was out with my family and i found a pile of (i believe it is, i'm not 100% sure) acacia tree.
so i took some pieces with me, clean them a bit and dump them in large bucket with water
after i while when they were already sank, i dropped salt in the bucket
i left them for about 3 months
the other day i pick them and rubbed them real good, using a toothbrush, peeling them off, even used a wire brush
then i boiled them for a while, a lot of tannin's was released, throw out that water and repeat the boiling again, this time the water is still with tannin's but in lower amount (maybe 50%)
should i continue to repeat the boiling process?

what should i do next?

I'd be concerned salt was going to leech out of it into your water, altho I don't know for sure.

Seems like you are doing things right to me. Depends on how much tannins you want in the water. You could repeat what you did (without the scrub) if you don't want any or just leave it
