Frequently Asked Questions
How often should I wash a reusable fleece liner?
Spot-clean daily for solid waste and rotate liners; do a full machine wash weekly or sooner if urine odor or visible staining appears. Frequent rotation extends the liner’s effective life and helps prevent lingering smells.
Do waterproof backings trap moisture against my pet’s feet?
Good multi-layer liners are designed to wick moisture into an absorbent core and away from the top fleece layer, so pets stay dry. Avoid single-layer, non-breathable plastics directly under a pet — they can trap moisture against paws and are less comfortable.
My liner smells after washing — how can I reduce odor?
Remove solids before washing, use a gentle, fragrance-free detergent and run a full rinse cycle; occasional sun-drying helps neutralize odors. If smells persist, increase wash frequency or rotate with a spare liner so each gets a thorough cleaning and drying period.
