My spider mister nozzles clogged and dripped Pryethrin on the concrete walks, leaving stains. Any suggestions for how to clean the residue?
If staining or a spill of the Riptide 5.0% Pyrethrin ULV had occurred on the concrete, we would recommend using an absorbent product such as sand, kitty litter, or similar material to soak up as much of the residue from the porous surface of the concrete as you can. If a stain remains, you may need to try a pressure washer or a concrete stain remover from a hardware store.
