I couldn't say it before Pesach b/c I didn't want to be be מכשיל the oilam but I received a special, unprecedented, coronavirus-tkufah-special-heter to use bleach to clean my toilets etc. that DIDN'T HAVE A KOSHER LA-PESACH stamp.
There.
I spilled the beans.
This heter is ONLY for this year and in future years we must again make sure that we can halachically drink our poisonous products [if not for the איסור of מאבד עצמו לדעת].
