Darker foods works only with vegetables and fruit. If your meat is dark, there's a limit to how dark it should be.
Also, hooray me. I figured out a way to TRIPLE my cleaning speed when cleaning the bathroom.
Bleach + spray bottle = fuckin' fast cleaning.
I cleaned the entire bathroom, including all walls and even the ceiling, in half an hour.
Usually, I only manage to clean the toilet, shower, basin and floor in about an hour and a half.
