While toilet brushes can reach the surface of the toilet, they often struggle to reach crevices, corners, and other difficult-to-reach areas. A toilet spray gun, on the other hand, uses a high-pressure jet of water to precisely reach every corner of the toilet, easily flushing away even the most stubborn stains and hidden dirt. For example, the toilet spray gun can fully reach areas prone to dirt and grime, such as under the rim and near the drain outlet, achieving a deep clean and leaving no dead corners or residue.
