Clean Grout Joints

Clean Grout Joints

No matter how careful you are, you're bound to end up with some thin-set in the joints between tiles. And if you allow it to harden, it'll interfere with your grout job. A toothbrush works great to clean excess thin-set from grout joints, especially for the skinny joints between mosaic tiles. Let the thin-set get firm, but not hard, before you start the cleanup process. If you try to clean up thin-set too soon, you risk disturbing the tiles.

Spot Cleaning

Keep an old toothbrush to spot clean stains and spills on clothes or for messes around the house. To spot clean a spill on clothes gently work the cleaning agent of your choice into the stain. Use an up-and-down motion with the brush, tapping the stain with the bristles. Don't use a back-and-forth motion because it can damage the fibers of the garment.

Locate Studs

Finding a stud behind plaster and lath is hit-or-miss with a typical stud finder. Here’s a better method. Tape a rare earth magnet (about $4 for a 10-pack at home centers) to a piece of dental floss. Slowly drag the magnet across the wall surface. The magnet will “hang up” a bit over the nails used to fasten the wood lath to the studs.

Toothbrush Glue Spreader

Toothbrush Glue Spreader

Old toothbrushes are great for gluing and avoiding a mess. When your toothbrush wears out, put it back into service as a glue spreader. I always use a toothbrush to apply glue to boards for edge-glueing. No more spreading glue with my fingers or chips of wood. The soft-but-not-mushy bristles of an old toothbrush apply glue evenly and quickly. One swipe along the edge usually does the trick, coating the surface smoothly and evenly. Store the brush in a glass of water.
