Chrome neutralization after plating

2007

After bright nickel and chrome plating rinsing is done.Need to neutralize chrome traces on the plated part. How to do it.

I don't think there is a stain-free neutralizing treatment. I believe you need excellent DI rinsing.

Can't you insert a tank containing sodium metabisulphite solution after the chrome dragout tank and before the water rinsing?

Dear Farooq,
Try a 10% sodium bi sulphite final dip as the final rinse before dying.

Is there a decorative chrome plater out there who is actually using a neutralizing treatment, please? When I was employed by Lancy we did use the "integrated" neutralizing treatment after chromating (we used hydrazine as the neutralizer in those days), but unless I wasn't paying attention, we didn't use it on decorative chrome plating.
