I stared using a solution of Vinegar and water to clean my tile floors and the results are amazing. I always used a steam mop to prevent toxins in my house since I have a child and animals. I love how my tiles look after and this is a great "toxin free" and "going green" solution for when you clean.
I also came across this awesome site that lists a ton of other ways you could use this solution when you clean.
