How To Clean Zinus Mattress: Step‑by‑Step Care Guide

If you’re wondering how to clean Zinus mattress safely without damaging the foam or cover, you’re not alone. Many sleepers want to deal with spills, stains, and everyday freshness while still protecting their mattress for the long term.

Below you’ll find clear answers to the most common questions about cleaning and caring for this type of mattress.

Can You Wash a Zinus Mattress Cover in the Washing Machine?

Most foam mattress covers, including those on many Zinus models, are not designed for machine washing. The fabric can shrink, lose shape, or the zipper and seams can be damaged.

  • If your cover is removable, it usually means it can be spot cleaned, not fully washed.
  • If your cover is non‑removable, it should stay on, and you clean only the surface.

Always check any care tag on the cover. When in doubt, treat the cover as spot-clean only with mild products.

How To Clean Zinus Mattress: Basic Surface Cleaning

For regular upkeep, focus on light surface cleaning and odor control rather than deep saturation.

Step-by-step basic clean

  1. Strip the bed
    Remove all sheets, protectors, and bedding.

  2. Vacuum the surface
    Use a handheld or upholstery attachment to gently vacuum the top and sides.

    • This helps remove dust, crumbs, and hair.
    • Avoid pressing too hard into the foam.

  3. Spot clean stains
    Mix a mild solution:

    • Cool or lukewarm water
    • A small amount of gentle liquid soap or mild detergent

    Lightly dampen a clean cloth with the solution and blot the stain.

    • Work from the outside of the stain inward.
    • Avoid soaking the fabric or foam.
    • Follow with a second cloth dampened with plain water to blot away soap residue.

  4. Dry thoroughly
    Blot with a dry towel to absorb as much moisture as possible.

    • Let the mattress air dry completely in a well-ventilated room.
    • Do not put bedding back on until it’s fully dry to the touch.

What’s the Best Way To Remove Odors?

Memory foam and other foams can hold onto odors if they get wet, so the goal is gentle, dry deodorizing.

Using baking soda

Sprinkle a thin, even layer of baking soda over the mattress surface and leave it for several hours, or longer if possible. Then vacuum it off.

This simple step can help:

  • Reduce light odors
  • Freshen the surface between washes of your bedding

Avoid strong-scented sprays that may leave residue in the foam. Lightly scented fabric sprays on bedding (not directly on the foam) are usually a safer choice if you want added freshness.

How Do You Clean Spills or Accidents on a Zinus Mattress?

When accidents happen, speed matters. The sooner you act, the less likely a stain or odor will set.

For fresh liquid spills

  1. Blot, don’t rub
    Use paper towels or a clean dry cloth to gently press on the spill and draw out as much liquid as possible.

  2. Apply a mild cleaning solution
    Use the same mild soap-and-water mixture described earlier.

    • Lightly dab the area with a dampened cloth.
    • Do not pour liquid directly onto the mattress.

  3. Blot again with a dry towel
    Remove as much moisture as you can.

  4. Air dry completely
    Good airflow is key. A fan can help, but avoid direct high heat, which can affect foam.

For older or tougher stains

You can use a slightly stronger solution with a small amount of white vinegar mixed with water. Test on an inconspicuous spot first to be sure the fabric tolerates it. Again, use minimal moisture and plenty of drying time.

What Cleaning Methods Should You Avoid?

Some methods can damage foam or fabric and are best skipped.

Avoid:

  • Soaking the mattress or using steam cleaners
  • Bleach or harsh chemical cleaners
  • Strong solvents
  • Scrubbing aggressively with stiff brushes
  • Direct high heat (hair dryers on hot, heaters, etc.)

These can affect the structure of the foam, cause discoloration, or weaken the cover fabric.

How Often Should You Clean a Zinus Mattress?

For ongoing care, a simple maintenance routine goes a long way:

  • Vacuum the mattress surface every 1–3 months
  • Spot clean stains as soon as you notice them
  • Use a washable mattress protector to reduce the need for deeper cleaning
  • Air out your mattress occasionally by leaving it uncovered in a well‑ventilated room for a few hours

This light routine can help keep your bed feeling fresher day to day.

Does Cleaning Affect Mattress Performance?

Gentle cleaning with mild products should not change how the mattress feels. Issues usually arise when:

  • Too much liquid soaks into the foam
  • Harsh chemicals are used
  • The cover is machine washed against instructions and shrinks or warps

If you keep cleaning light and careful, your mattress should maintain its expected comfort and support over time.
