When our boys didn’t listen, I told them keep it clean or I will toss ALL your clothes in the garbage.
Of course nothing changed, so one day I took everything that wasn’t hung up or in a drawer (almost all their clothes) and put them in bags in MY closet.
When they got home they were frantic after going to their room.
Running to me “Where are our clothes?!!!”
In the dumpster…I told you what I would do.
After them dumpster diving for half hour , I showed them the bags of clothes. Then I said , put them away , hang them up , and keep it that way or next time you won’t have them/
Problem solved. Man were they ever mad! lol but it worked
