The toothpaste & hairdryer crayon buster
A safe fix for a crayon texta on wall. AI-drafted, human safety-reviewed, and honest about where it stops: if you reach the stop point below, that is a tradie job, not a you job.
You will need
- White non-gel toothpaste (e.g. Colgate Regular) · Woolies/Coles, ~$2
- Old soft toothbrush · Any old one from the bathroom drawer
- Hairdryer · Any household hairdryer
- Magic Eraser (melamine sponge) · Bunnings or Woolies, ~$5 for a twin pack
- Damp microfibre cloth · Bunnings ~$3, or any soft cloth from home
- Small bowl of warm water
Step 1
Warm up the wax first
Hold a hairdryer on medium heat about 5 cm from the crayon marks for 20–30 seconds. The wax in crayons softens with gentle heat, making it much easier to lift off the wall without smearing. Don't overheat — just warm to the touch is plenty.
Step 2
Toothpaste scrub for crayon
Squeeze a small blob of white non-gel toothpaste onto the old toothbrush and gently scrub the crayon marks in a small circular motion. The mild abrasive in toothpaste lifts the wax without damaging standard painted walls. Wipe away residue with a damp cloth as you go.
Step 3
Magic Eraser for texta/marker
Dampen the Magic Eraser slightly with water and rub gently over any texta or marker lines using light, even pressure. These melamine sponges are surprisingly powerful on marker ink — go easy so you don't dull the paint sheen. Work in small sections and rinse the eraser regularly.
Step 4
Wipe clean and check
Once the marks are gone, wipe the whole area with a clean damp microfibre cloth to remove any toothpaste or residue. Step back and check in good light — repeat either method on any stubborn spots. Let the wall dry fully before deciding if a touch-up paint is needed.
The stop point
If the marks have soaked deeply into raw or unprimed bare plaster, or if the paint starts peeling or pilling as you scrub → stop and call a painter to repaint that section rather than risk making it worse.
