Rinse them then let them dry. You do not want to mix reagents.
- They are different brands
- Different dye lot numbers
Some will debate or have a difference of opinion but honestly rinsing them out in such a short task why not. I have not used ABC reagents but OEM ones I don't even mix. Different lot numbers which could mean different dye colors. Yes it will be the same in theory but sort of like buying tile or similar flooring. Buy enough for the job to prevent the risk of a slight variation.
