I would really prefer we didn't ban caustic soda.
It's so useful for cleaning drains.
Lots of cleaning products can be dangerous.
You shouldn't mix bleach and detergents for example.
It's important to read packets or if you can't due to language or LD issues it's important to either phone the advice line or ask for help from a carer.
In other places you can buy lye, sulphuric acid and all sorts in the cleaning aisle. It's already too much of a nanny state here.
I've saved money on plumber call out fees being able to use caustic soda.
But I know I'm not able to use it in oven cleaning because I don't have the skill set.
I don't think it's possible to eliminate the possibility of any and all accidents by banning all potentially dangerous products.
