Crayon on Mattress

timer

Crayon is wax-based — heat will melt and spread it, so always use cold methods first.

checklistTreatment Steps

Step 1: Freeze the Wax

Place the item in the freezer for 30 minutes to harden the wax. Once hard, use a blunt knife to carefully scrape off as much wax as possible.

Step 2: Apply Dish Soap

Apply a generous amount of dish soap directly to the remaining stain. The dish soap cuts through the wax and dye components.

Step 3: Scrub Gently

Use an old toothbrush to gently scrub the dish soap into the stain. Work in circular motions for 3–5 minutes.

Step 4: Wash on Warm Cycle

Wash on a warm (not hot) cycle. The warmth helps release the remaining wax while the detergent lifts the dye. Check before drying.

Step 5: Special Care for Mattress

After treatment, sprinkle baking soda generously across the area to absorb residual moisture and odours. Leave for at least 4–6 hours (ideally overnight), then vacuum thoroughly. Air the mattress before re-dressing.

Critical Warning

Mattresses cannot be saturated — excess liquid soaks into the foam or springs and causes mould, odours, and permanent damage. Use as little moisture as humanly possible. Never use a steam cleaner unless specifically rated for mattresses. Avoid bleach and harsh chemicals — they damage foam and leave residues you'll sleep on.

Pro Tip

WD-40 is highly effective on crayon — spray a small amount on the stain, let it sit for 5 minutes, then treat with dish soap. The oil in WD-40 dissolves the wax binder. — Use cold water only — heat can set proteins (sweat, urine, blood) and warm conditions encourage mould growth inside the mattress.
