William;
There are a couple of issues to consider.
1. Alkaline cleaners, like our PowerMax, are the safest cleaners for Tile & Grout.
2. Strong acid cleaners w/ a solvent (our Grout Cln) can actually clean better, but with more risk.

Acid cleaners wont clean properly if you have grease on the floor. Alkaline wont always get grout restored as well as possible. You need both to do the best job possible.
You may not always need acid to do a great job. And some times even acid wont cut it, and color sealing is required. Or possibly having to remove floor finish that shouldn't be there in the first place. While there is risk like Cobb stated, (stainless appliances, or metals, many stone tiles etc) with experience and care you wont have a problem using it.
Keep in mind when you are cleaning tile.
Alkaline- is for grease and most dirt, spills and most important for cleaning the actual tile. Also needed to remove a grease layer on grout so that acid can be used.
Acid- is for dissolving calcium in grout removing a very thin layer. Not to be used on tile reacts to acid.
Both have their purpose, and both should be on the truck if you aren't a hack.
