It should be 1:4.
Sorry if we sent the wrong instructions.

Based on this, I've been using a 1:4 ratio for the last 4 weeks! It has been working, but now I'm unsure if it's optimal.

Good luck! Let us know how it works out. |
Will do, but now I want to follow this thread
I read your reply, read the linked thread where Caswell told the other poster to use 4 water to 1 blackener 13 months ago, checked my bottle to verify it is "New Formula", then called in. They said the sheets they get from MFG of chems states 10% by volume, which is 9:1, but I told them about the thread where 4:1 was described as correct by Caswell, and they were replacing the Blackener, and sending me a plate and more zinc solution to make up for the time lost.
Now I don't know what to do. The person on the phone said that 65F to 90F is OK temps, and when asked if hotter was better, they said they would think so.
I'll wait for the blackener, plate, and solution to arrive, try some more things, and keep an eye on this thread to find out what the correct ratio is, 9:1 or 4:1. I'm inclined to try 4:1 if you said it was working for you.
