AI picks by need

Not for: Anyone needing to remove mineral deposits or efflorescence, which need an acid.
What the AI looks for in Tile Grout Cleaners
- Chemistry vs soil
- Use alkaline cleaners for grease and body oil, and acidic cleaners for mineral deposits and hard-water film. The wrong chemistry barely moves the stain.
- Adjacent surface
- Never use acidic grout cleaners where the tile is acid-sensitive stone. Acid etches the stone next to the grout.
- Grout type
- Cement grout tolerates scrubbing, while epoxy grout rarely needs more than a neutral cleaner. Harsh products are wasted on epoxy and can dull it.
- Reseal after
- Let cement grout dry fully after deep cleaning, then apply a penetrating sealer. Deep cleaning removes existing sealer and leaves grout porous.
Brands that matter
- Zep: Widely available grout and floor chemicals.
- Aqua Mix: A tile-trade grout care line.
- Custom Building Products: TileLab grout cleaners and sealers.
What to avoid
- Bleach on colored grout
- Wire brushes on grout, which erode the joints
- Acid grout cleaners near natural stone
Questions
Will cleaning make stained grout look new?
Not always. Deeply stained cement grout often needs a grout colorant after cleaning.
