VERY CAREFULLY.

If it's real fur, you'll want to handwash it. But if it's costume fur, depending on how large the tail is, you can use your washing machine. Just skip using a dryer and just let the tail air-dry. You'll probably have to do a lot of brushing afterward.

ok, thank you!!!

I gotchu bro

uhh i thinkk you should find a skyhigh or neffernity vid on yt but my best guess is you should fill the sink or bath tub with COLD WATER and wash with laundry soap a few times. I hope this helps you.

also make sure that the cleaning area is actually clean and make sure to drain the sink/tub a few times too.

ok thank you, i mean people say putting it in the washer also works, just as long as the water is old
just don't put it in the dryer

Yeah

Leave it in fluoroantimonic acid

Sit in a washing machine and turn it on
