How to Clean Grout

Still busy with house stuff here.  I thought I'd let you in on some of the things I've been learning as a new homeowner.  The previous owners left a lot of trash and grunge.  One of the worst things was the tile grout.  I tried a few different products but the most effective I found was vinegar. 

1. Microwave vinegar for 3 min in glass measuring cup
2. Pour directly on grout in a 5ftx5ft area
3. Let sit for five minutes
4. Use grout brush to loosen dirt
5. Wipe away with a damp cloth
6. Mop area with regular floor cleaner.

The before picture makes me cringe.  It is gross and it takes a little time to do BUT it works and it is cheap.  I like the fact that the vinegar can't hurt your cloths or pets or kids. I still have a lot of grout to clean but I'm just doing it in little patches.
