Apply a paste of baking soda and hydrogen peroxide directly to the dirty grout lines. Scrub the mixture gently with a stiff brush and rinse the area thoroughly with clean water.

Cleaning urine out of unsealed grout with a scrubber requires a multi-step approach that involves absorbing fresh liquid, applying a targeted cleaning solution to break down uric acid crystals, and gently agitating the porous surface without damaging the grout lines. Because unsealed grout acts like a sponge, simply wiping the surface is never enough to eliminate deep-set stains and lingering odors.

Before reaching for any cleaning tools or solutions, you must address whatever liquid is currently sitting on the surface and within the upper layers of the grout channels. If the mess is fresh, take dry paper towels or a clean, absorbent cloth and press firmly directly over the affected area. Avoid wiping or smearing the liquid, as this pushes the urine deeper into the porous grout matrix and spreads the contamination over a wider area of the surrounding tile.

Continue pressing down with fresh towels until no more moisture transfers to the paper. If the urine has already dried, lightly mist the area with plain warm water to soften the crust, then blot it up immediately. Taking the time to remove as much liquid as possible keeps the upcoming cleaning steps from having to fight an unnecessary surplus of moisture, allowing your cleaning agents to concentrate entirely on the embedded residue.

Applying an Enzymatic Cleaner

Standard household surface sprays rarely solve urine issues on unsealed grout because they fail to neutralize uric acid crystals, which are the root cause of persistent, sharp odors. Instead, apply a liquid enzymatic cleaner designed specifically to break down organic waste. Pour or spray the solution generously over the affected grout lines, ensuring that the liquid pools slightly in the depressed channels between the tiles.

Once applied, do not wipe it away immediately. Enzymatic formulas require time to work; the specialized proteins must consume and liquefy the uric acid compounds trapped inside the microscopic pores of the unsealed cement. Check the manufacturer's instructions for the appropriate dwell time, which usually ranges from ten to thirty minutes.

Extracting the Lifted Contaminants

Scrubbing loosens the trapped waste, but if you simply let it dry back into the floor, the urine remains trapped in the room. You must physically remove the slurry that has formed on the surface. Take a stack of clean, dry microfiber cloths or paper towels and press them firmly into the grout channels to soak up the dirty liquid. Alternatively, use a wet-dry vacuum if you are dealing with a larger area, running the nozzle slowly along the grout lines to suck away the moisture and suspended debris.

After the initial extraction, rinse the area thoroughly. Pour a small amount of clean, warm water over the grout to flush out any remaining chemical residue and loosened dirt, then blot or vacuum that rinse water away as well.

Drying and Preventing Future Absorption

The final stage is ensuring the floor dries completely and taking steps to protect the vulnerable surface moving forward. Turn on ceiling fans, open nearby windows, or place a portable fan blowing directly across the floor to accelerate the evaporation process. Unsealed grout holds moisture for a long time, and leaving it damp can lead to mold growth or musty smells that mimic the original problem.

Once the floor is completely dry to the touch, evaluate the condition of the grout.
