It’s passive protection — no electricity, no cost, no effort.
What NOT to Do Before You Leave
❌ Don’t pour water down the drain “to keep the trap full”
— It will still evaporate in hot weather.
❌ Don’t leave the sink wet and uncovered
— Invites mold and bugs.
❌ Don’t use plastic wrap or tape
— Can melt, look messy, or damage surfaces.
✅ Do this instead : The glass-and-paper method is cleaner, safer, and more effective.
