Ah, now that I don't know
Mine cleaned out fine after the deerskin though.
I was doing some research into Inuit clothing for a seminar presentation and came across a 'new method' they employed to tan skins. Inuit are incredibly capable people and they fully appreciate gadgets. The are also incredibly practical.
So, anything that helps cut down labour and still produces a good quality product is considered a good thing.
Scrape skins clean of all visceral tissues. Bung it into the washing machine with biological washing liquid and wash cool, but, make sure to add 3 or 4 times the normal quantity of fabric conditioner.
Haul out the skin after a decent spin (set washing machine to hot, add biological liquid and let it do an empty boil wash and that'll clean everything fit for use for normal stuff afterwards) stretch skin as usual, but as it dries rub in masses of handcream (avon skin so soft smells good years later
) into the skin side and when the skin is almost dry start to work it. It will still need a lot of work if you want a soft handling skin but the result is beatiful. It's really just a rawhide method but no brains needed.....if I make myself clear
cheers,
