That's a deep-clean recipe and it's awesome for dissolving dirt and lint etc... but it won't actually remove wax. Wax takes a lot of hard work to remove and very, very, very hot water.
said:Here's a recipe to remove wax that may work (I hear it's wonderful!). In fairness, I pulled it from a dread site that pulled it from another dread site (http://dreadlocktruth.com/community/index.php?name=Forums&file=...):
Grab a big bowl of warm water, or hot-ish if you can stand it. (as hot as possible)
Add 3/4 cup of baking soda,
8-9 drops of tea tree oil,
2 table spoons of lemon juice,
and 2 table spoons of sea salt,
stir and stir until it's dissolved.
Soak dreads in the bowl or use a squirt bottle or something similar to apply it to your scalp and dreads.
Grab a towel and wrap it around your head and leave it there for around half an hour, or more.
Rinse it out, really well. And that's it!
