Rinse Thoroughly

After allowing sufficient contact time as per the instructions, thoroughly rinse treated surfaces with water to remove residue. This reduces the likelihood of residual chemicals coming into contact with skin or pets.

Alternative Eco-Friendly Options

Consider Natural Alternatives

For those concerned about chemical exposure, consider eco-friendly alternatives such as vinegar solutions, hydrogen peroxide, or homemade cleaners using natural ingredients.
