LESSON 3 · Potty Training Done Right
The Blacklight Sweep
A blacklight doesn't just find one stain — it maps your whole problem. Wait until dark, kill the lights, and sweep each room slowly: floors, baseboards, the legs of furniture.
Owners are often shocked. A dog they thought had the "occasional" accident turns out to have three or four regular spots, each one a scent marker quietly pulling them back.
Mark every glowing spot with a piece of tape. Treat them all with enzymatic cleaner, then recheck with the blacklight once it dries to be sure each one is truly gone.
