The plot thickens. You are using the two part hardening formula? That would be adding an unknown variable. I'd say try some tradition Hypo, Sodium Thiosulfate made from scratch.

and stop using Dust Off nobody had it 150 years ago
Dust-Off, a popular brand name of canned air, is a gaseous refrigerant-based propellant cleaner used to remove dust and dirt from computers and electronics. The main ingredient in Dust-Off is difluoroethane.

If your development times and pre-fix wash times are as you've stated, then one of the only other variables is the fixer: change to something else. I suggest you try plain Sodium thiosulfate, or even Ilford Rapid Fix.
First, there isn't a "dilution" with hypo, you buy crystals, and make it yourself with water. Second, when you say "do you think would work...?" I don't have to "imagine or guess" what might work, Hypo is all I've used for fixer since I started doing Wetplates, in 2006. It and one other are the standard fixers, used since the 1850s.
The standard formula is out there, in several manuals and probably websites like the old Collodion.com. I'd have to go look it up, I make it only once in a while and don't have it memorized, but I think it's about a 20% formula. You probably need to buy a wetplate guide and you'll have all your questions answered. I like John Coffer's Dooers Guide, but Quinn Jacobson's is good too.
