(quick step by step guide)
Wear gloves, apron, and tie your hair up. It's not cool to get lice on yourself!
Remove the bedsheets, pillowcases, blankets, duvet.
Separate the washable and "dry clean only" pillows/beddings - Only wash the washable ones.
First cycle - Wash with detergent and hot water to kill the lice.
Second cycle - Just hot water to flush out the remaining ones.
Slow spin speed for both cycles.
After washing, put the pillows and beddings into the dryer. High heat setting. As long as required to dry.
Keep the washed pillow and bedding in a sealed ziploc bag.
Any remaining lice will die off within 7-10 days without a human to feed on.
Sweep through mattress, pillows, and even the bed frame thoroughly.
There are no good ways to throughly clean them without professional tools.
Best to send them to professional cleaners.
