How do you clean urine from a mattress topper?

Blot excess, spray with enzyme cleaner, let sit 15 minutes, blot dry. Cover with baking soda, let dry completely, then vacuum.

How often should you clean a mattress topper?

Vacuum monthly. Baking soda deodorize every 3 months. Spot clean stains as they happen.

3-5 years for memory foam, 2-3 for cotton. Replace when it no longer provides support or comfort.

Never put memory foam in a dryer. Cotton and down toppers can go on low heat if the label allows.

Bedroom

We spend a third of our lives in bed. A clean mattress topper means better sleep and fewer allergens. Here's how to clean yours.

1
Vacuum the surface
Remove all bedding and vacuum the entire topper surface to remove dust, dead skin, and allergens.
2
Deodorize with baking soda
Sprinkle baking soda over the entire surface. Let it sit for at least an hour (longer is better). Vacuum it up.
3
Spot-clean stains
Spray Vibes Multi-Surface Cleaner on stains and blot with a clean cloth. Never soak a memory foam topper.
4
Air out and flip
Stand the topper against a wall near an open window to air out. If it's double-sided, flip it for even wear.

TIPMemory foam toppers cannot be machine washed or soaked. Spot cleaning and baking soda deodorizing are the only safe methods.
TIPUse a mattress protector on top of your topper to simplify cleaning and extend its life.
TIPFor cotton or down toppers, check the label -- some are machine washable on gentle cold.

XMachine washing a memory foam topper, which destroys the foam structure permanently.
XSoaking memory foam with liquid, which takes days to dry and almost always develops mold inside.
XWringing or twisting memory foam, which tears the foam and creates permanent indentations.

Only if it's cotton or polyester fill AND the label says machine washable. Never machine wash memory foam.
