Zinc plating
AshimotoK0:
I just use the zinc plating chemicals from Gateros. The brighteners they use are spot on. I know they sell the top-up 'maintenance' brighteners separately but not so sure about the brightener they use on initial mixing of the zinc electrolyte. I did once try YouPlate zinc plating chemicals but big mistake as the brighteners they use gave me crap results. I discussed this with them but in the end I just bolted with my feet at went back to Gateros. I have seen saccharine suggested as a brighter but never tried it.

Thank Ash,
That's where I have been looking, there's the leveller make up and brightener available.
Other brighteners could be aliphatic polyamines, furfural,thiourea, vanilla extract and derivatives.
Regards
Dave

I too use Gateros and just add a few drops of their maintenance chemical if the the plating gets dull. Getting the amps right and the temperature at 25c. Bags on the anodes helps to keep the electrolyte clean and filter it after each use.
Fair to say the vinegar does stink a bit so I just keep it out of the way and it does take a couple of days to dissolve the rust. Some parts might take longer especially something like that shown in the image that's in it now. The river it was found in has not been disclosed!

That's looking a bit of a mess. Though the plate inside looks like it's still there.
The worse bits I have seen on them is the outside at the bottom where they sit in water in the bowls and the pitting can be quite deep.
