Re: Sodium Hydroxide (Caustic soda) Alternative
Right - use the Caswell de-oxidizer and de-smut. They sell it separately. I never used it before but I tried it recently. I didn't notice any difference in my results but I use strictly 6061 and I think the desmut removes surface copper, which I don't think 6061 has much of anyway. I just go right from Spray Nine and rinse really well to the anodizing tank.
