Apply liquid adhesive to dirty tile lines and let it dry completely. Peel away the hardened film to lift out embedded dirt and reveal a clean surface.

To use glue to clean grout with a brush, you apply a thin layer of common school glue over dirty tile lines, let it dry completely, and then peel away the hardened film to pull embedded dirt and stains out of the pores. This unconventional method relies on the adhesive's ability to bond with microscopic particles of grime, lifting them out of rough surfaces as the plasticized sheet is removed.

Before starting, it helps to understand why this technique works. Traditional scrubbing requires significant physical exertion and harsh chemicals to dislodge deeply set stains in cementitious joints. By contrast, a liquid polymer seeps into the microscopic crevices of the surface, surrounds the trapped dirt particles, and hardens into a flexible sheet. When you peel the dried film away, the dirt comes with it. While this method requires patience, it avoids the strong fumes and potential tile damage associated with heavy-duty chemical cleaners.

Prepare the Work Area and Clean the Surface

Begin by clearing the floor or wall of any loose debris, dust, and larger particles.

Next, wipe the tiles and joints with a damp cloth using plain water to remove surface oils, grease, and soap scum. Do not use strong detergents or wax-based cleaners during this initial wipe-down, as residual chemicals can prevent the adhesive from making proper contact with the surface. Allow the entire area to dry completely before moving to the next step. Moisture in the joints will slow down the drying time of the adhesive and might weaken its bond to the dirt.

Apply the Adhesive to the Joints

Work in a manageable section, such as a three-foot by three-foot area, so the process remains organized and you do not accidentally step on the wet material.

Carefully trace the lines of the joints, squeezing a steady, thin stream directly into the recessed channels. You want enough liquid to fill the groove and coat the sides, but not so much that it pools heavily over the adjacent tiles. If large puddles form on the flat surfaces of the tiles, use a damp rag or a fingertip to wipe them away. The goal is to cover only the dirty joints where the cleaning action is actually needed.

Spread the Polymer with a Brush

Take a clean, stiff-bristled utility brush or a small paintbrush and use it to work the liquid evenly along the channels. Gently drag the bristles back and forth to ensure the adhesive penetrates every microscopic pit and texture of the surface. This mechanical action forces the polymer into direct contact with the deeply embedded soil, oils, and discoloration that routine sweeping leaves behind.

Take your time during this stage to ensure complete coverage. If you notice any gaps or thin spots where the underlying surface is still visible through the liquid, squeeze a tiny drop more into that spot and brush it smooth. The layer should be uniform throughout the entire section. Once the lines are thoroughly coated and smoothed out, step back and leave the area undisturbed.

Avoid walking near the work zone, as airborne dust or pet hair might settle onto the tacky surface and become permanently embedded in the plastic sheet.

You will know the material is ready to remove when the milky white liquid turns completely clear and feels firm and dry to the touch. If you press a fingernail gently against the cured film and it still feels soft, tacky, or spongy underneath, wait longer. Peeling the material before it has fully set will cause it to tear into tiny, frustrating fragments instead of coming off in one cohesive piece.

Peel and Lift the Dirt Away

Locate an edge of the dried polymer film, usually where it accumulated slightly thicker against the corner of a tile. Use your fingernail or the edge of a plastic scraper to gently lift the corner upward. Once you have a secure grip on a small tab, pull the film steadily back and away from the channel at a low angle.

As you pull, the dried sheet should lift cleanly out of the groove, taking the trapped grime, stains, and discoloration with it. You may notice the underside of the peeled strip looks gray or discolored, which indicates that the adhesive successfully bonded to and removed the dirt from the porous surface. Continue pulling until you have removed the entire strip from that section.

Inspect and Repeat Where Necessary

Examine the newly uncovered joints under a bright light. You will likely see a dramatic improvement in brightness, with the natural color of the material restored in most areas. However, deeply set stains or exceptionally old discoloration might require a second application to fully resolve.

For stubborn spots, simply repeat the process. Apply a fresh stream of the liquid to the remaining dark areas, brush it in thoroughly to ensure maximum contact, let it dry completely, and peel it away once more. This targeted secondary treatment addresses areas that resisted the initial cleaning cycle without requiring you to redo the entire surface.

Final Sweep and Maintenance

Wipe the tiles with a damp cloth to remove any faint residue and restore their natural shine.

To keep the joints looking clean for as long as possible, establish a regular maintenance routine. Sweep frequently to prevent abrasive dirt from settling into the porous material, and wipe up spills immediately so they do not have a chance to soak in. While this glue and brush method provides a deep restorative clean, regular light upkeep will reduce how often you need to perform intensive cleaning tasks in the future.
