How to (almost) clean grout: attempt 2

Pour some powdered bleach into a bowl.

Add some water to make it into a paste.

Before photo.

Scrub it all over.

Half hour later.

Couple hours later after rinsing and wiping up with a sponge. That actually looks a bit better. Not amazing, but better.

Conclusion, I'm tempted to try out the brand name OxiClean to see if I get better results. Shame I can't use my Lysol mold remover spray. That's amazing stuff.
