To all chemists: What sort of compound would dissolve clothing, yet not at all react with skin and hair?

Lots of moths and larva can eat clothes and leave skin and hair alone. Biology not chemistry. I hope it helps. Have fun making a slime monster.

Pheromones can make clothing disappear.

Loli, I’ve invented such a substance. I spray it on anyone who annoys me, so that I can point to and giggle at their private parts, but without actually harming the person. But, I regret that I won’t share the formula; it’s my own.

Maybe you where watching Star Trek TNG where Data was kidnapped by a collector? Where he threw acid on his star fleet uniform. To get him in civilian clothes. If you want to justify from the fictional universes president?
