How To Clean a Cot Mattress: Simple Steps for a Fresher Sleep Space

If you’re searching for How To Clean a Cot Mattress, you’re likely dealing with spills, accidents, or everyday dust and sweat. This guide walks through safe, simple steps to clean a cot mattress, remove common stains, and keep it fresh without harsh methods.

What Does Cleaning a Cot Mattress Involve?

Cleaning a cot mattress usually means:

  • Removing surface dust and crumbs
  • Treating spills, stains, and accidents
  • Reducing odours
  • Allowing the mattress to dry fully before use

Because cot mattresses are used by babies and young children, gentle, low-residue cleaning methods are especially important.

How To Clean a Cot Mattress: Step-by-Step

1. Check the Care Label First

Before doing anything, read the manufacturer’s care instructions. Some cot mattresses have:

  • A removable, machine-washable cover
  • A waterproof layer that should not be punctured
  • Foam or inner materials that should not be soaked

Always follow those instructions over any general advice.

2. Start With a Basic Surface Clean

  1. Remove bedding and protectors. Strip everything off the mattress.
  2. Vacuum the surface. Use a clean upholstery attachment to remove dust, hair, and crumbs.
  3. Wipe down waterproof surfaces. If the cot mattress has a waterproof cover, use a slightly damp cloth with mild soap, then wipe again with plain water and let it air dry.

Avoid saturating the mattress, especially if it is foam-based.

How Do You Remove Common Stains from a Cot Mattress?

Treating Fresh Spills and Accidents

For milk, formula, or fresh urine:

  1. Blot, don’t rub. Use a clean, dry cloth or paper towels to absorb as much liquid as possible.
  2. Use a mild cleaning solution. Mix a small amount of gentle liquid soap with cool water.
  3. Spot clean. Lightly dab the area with the soapy solution using a clean cloth, then blot with a damp cloth (water only) to remove residue.
  4. Air dry thoroughly. Place the mattress in a well-ventilated area until fully dry on all sides.

Handling Dried Stains

For dried stains, the process is similar but may need more time:

  • Lightly dampen the area with water, then use mild soap solution.
  • Gently work on the stain with a cloth, avoiding scrubbing too hard.
  • Blot with a clean, damp cloth to remove any soap, then let it dry completely.

If the stain remains, repeat once more rather than using very strong chemicals.

How Can I Deodorise a Cot Mattress Safely?

Odours often come from absorbed moisture. To reduce smells:

  • Air the mattress out. Place it in a bright, ventilated room away from direct intense heat.
  • Lightly sprinkle baking soda. For fabric surfaces, a light dusting of baking soda can be left for a few hours, then carefully vacuumed up.
  • Avoid strong fragrances. Sprays with heavy perfumes may leave residue or be irritating to some children.

The focus should be on removing odours, not simply covering them up.

How Often Should You Clean a Cot Mattress?

The frequency depends on how often the cot is used and the number of spills or accidents. In general:

  • After any accident or major spill: Clean and dry the affected area immediately.
  • Every few weeks: Do a quick vacuum and visual check.
  • Periodically: Air the mattress out when you change bedding.

Regular light maintenance is usually easier and more effective than heavy cleaning done rarely.

What Should You Avoid When Cleaning a Cot Mattress?

Some methods can damage the mattress or leave it damp inside. It’s usually best to avoid:

  • Soaking or submerging the mattress in water
  • Harsh chemicals or bleach that can degrade materials
  • Very hot water or heat sources directly on the mattress
  • Scrubbing aggressively, which can damage covers or seams

✨ Aim for gentle, controlled cleaning with minimal moisture and thorough drying.

How Do I Know the Cot Mattress Is Dry Enough to Use?

Before putting on bedding again, check that:

  • The surface feels completely dry to the touch
  • There are no cool, damp patches when you press gently
  • There is no musty smell

If in doubt, give it extra drying time. Using the mattress while it is still damp internally can lead to lingering odours and general discomfort.

Is There a Difference Between Cleaning Waterproof and Fabric Cot Mattresses?

Yes.

  • Waterproof cot mattresses:

    • Usually easier to wipe clean
    • Often need just mild soap and water on the surface
    • Still require full drying before use

  • Fabric or quilted cot mattresses:

    • May absorb spills more quickly
    • Often benefit from immediate blotting and careful spot cleaning
    • Need more drying time and good air circulation

Always match your cleaning method to the specific type of cot mattress you have.
