Grout: the biggest mystery of housekeeping.

Recently I've tried using Clorox toilet bowl cleaner with bleach and then (yesterday) just straight laundry bleach to clean my floor grout. Neither had impressive results. Now I have some Zep, which contains hydrochloric acid. If I use this today and there is still bleach residue on the floor (I did mop with water), might I poison myself via a chemical reaction? The area is decently ventilated.
