Crayon companies recommend treating wax stains on clothes by spraying them with WD-40 lubricant, applying dishwashing liquid, and then washing them. Explain Why.
I don't know how to explain this. I keep looking things up for it and still don't under stand, if you know a good website please tell me. I need a chemistry type answer. If you can help me I would appreciate it.

The WD-40 disolves the crayon wax. The dishwashing liquid removes the WD-40.

It's easier to remove a liquid stain than a solid one. So the WD-40 lubricant dissolves the wax stain. The dishwashing liquid disperses the lubricant and the dissolved wax, which is diluted and disposed of the washing machine.

WD-40 is a very light oil.
Crayon is a wax.
Waxes are soluble in light oil.
The WD-40 will absorb and 'dilute' the wax to a light, thin, oily (greasy) liquid.
Washing up liquid is an excellent de-greaser.
