Cleaning & Laundry ruling
Can mop water go down the drain?
Normal, label-directed use is one thing. Disposing of leftover product is not normal use.

01
Why the pipe objects
Mop water may contain dirt, hair, grease, disinfectant or pesticide residue, so the contents matter more than the bucket.
02
Do this instead
Strain solids and follow the cleaner label; ask locally if the water contains oil, pesticide or other hazardous material.
03
Already did it?
Never combine cleaning products. If a large amount was poured out, ventilate the area, follow the product label and contact Poison Control or your wastewater authority for guidance.
