Be Careful When Cleaning the Bathroom

So yesterday I decided after editing for about 2 hours to clean the bathroom.
I hadn't cleaned the bathroom in quite some time due to fatigue, burnout, and studying for tests.
As you might assume, mold began to grow on the grout and walls[I know, gross.], so this was long overdo.
Everything went pretty well, until it was time to clean the shower. I used a foaming bleach cleaner, but the bathroom is pretty small and the only ventilation I had was a small open window.
Cuz of this, I started coughing horribly. So bad I was starting to see spots.
I had to step out a few times, and even grabbed a mask.
I did take proper precautions, such as opening the window beforehand, not mixing the spray with anything else, and wearing thick rubber gloves.
Afterwards, I had to put my fan in there, as the smell was so strong.
It's been over 24 hours, and it does still smell a bit, but it has still died down A LOT.
And don't worry, after I finished cleaning the bathroom I lied down for a bit, and a couple hours later I was pretty much back to normal.
There's two lessons to take away from this:
1. Do not wait a few months to clean the bathroom[especially when you live in a humid environment like I do]
2. When it comes to cleaners with strong smells, a little goes a long way.
But the bathroom looks so much better.
