If you use bleach and/or a grout sealer when you’re done make sure you ventilate really well.
I’m convinced that bleach fumes kill brain cells. (I have relatives addicted to bleach as my data points… just like in “My Big Fat Greek Wedding” – they use bleach for ALL cleaning and even put a drop of bleach in water and drink it to cure illness… and the effects can be seen. 😉 )
The tile/grout sealer is also pretty volatile till it evaporates – so make sure you have windows wide open and fans going.
