When ordinary people try to write instructions

Please do not dispose of paper towels or sanitary napkins in the toilets. Please use the waste baskets installed of the walls of each stall for such. Thank you Management.
Guys, what? The term "sanitary napkin" is hilariously outdated,
and the rest of this sign I can't even discuss.

How about:

Please do not flush
feminine products, baby wipes or paper towels.
Use trash receptacles.
