A. Vinegar and water. One part to three parts water. This is for floors and walls. Also I would like to note that mopping the floors can actually make your floors dirtier. When you push that mop forward you pick up the dirt, then when you pull back your leaving the dirt that you just mopped up behind. The best way to do it is to use a large sponge and wipe in one direction and then flip the sponge over and wipe with the other side, then rinse. Once the water in the bucket is dirty, you need to change it, don't keep using it. You'd be just putting the dirt back on the floor. If this sounds like to much work for you, especially if its a large floor, then just spot clean with a spray bottle of vinegar and water. This is usually all you need to do to keep up with the daily (or weekly if you prefer) cleaning. Then once every six months you could use a hard floor cleaner that puts the water down and sucks it back up or hire a carpet cleaner once a year to clean your tile. Don't let them sell you on the sealer for grout, its basically like that scotch guard they put on the carpet, it doesn't last. Please read post "Should I seal my grout".
