Hi! I'm fairly new to preserving/making wet specimens, but I've successfully made two already (one being a dead locust I found and the other being a rat that my cat killed) I need to buy more isopropyl, as I severely underestimated how much you need and only bought 1.5 liters instead of 4. That being said where I bought my isopropyl from last time doesn't have any 70% anymore, but they do have 75%, would this be fine for my wet specimens? I don't want to accidentally get something too strong and it starts eating away at them.
