To clean your crystals is very simple.
Place them on your hands under running water for a few minutes.
If possible, place them in a bowl with clean water in the sun for about 12 hours.
Another very good way of cleansing crystals is to put them in a bowl with sea salt over night.
(it doesn't have to be over night, it just needs to sit there for many hours. I find easier to do wash them
on the next day).
The smoke of an incense, sage, sweetgrass or even cedar are also great, just pass the crystal over the smoke for a few seconds and it can give you a quick cleansing. Although I prefer the sea salt over night, since it's more complete.
It is very important to clean your crystals, specially if you use them a lot for healing.
Enjoy the high energy!!
