In the famous words of a previous SM, ‘unless it’s poo, use the blue!’ Many partners prefer bleach to clean most things because it’s easy and quick as that stuff can melt someone’s face off. Do what you feel is right and I think your SM should have no qualms if things are being kept clean. ;)

we only use bleach to clean the drains on the floor, and boiling water to clean the sinks. we just got a new SM and she’s been spraying the hand washing sink with bleach and I’m having the same issue :) not sure if it’s against any rules though

We bleach the hand washing sinks but other then that the other sinks we use blue because it touches food or drinks
