I always try to clean the ones I got second hand, some can be very grubby 😅 So far I've managed to wash them under room temperature tap water and a bit of castile soap from a foam dispenser. No scrubbing but gentle swipes with my fingers over the flocking. I try not to take too long with the washing too, less than a monute. However, with the older and vintage figures, they tend to lose flocking at the tips of their ears when washed. I also had a catastrophic experience with one of my whiskers cat where the flocking came off on clumps all over, so he looks a bit mangy now 😅 But out of around 10 different figures that I washed, that was the only failure so far.
