There are various ways to clean crystals.
First the question: why should one clean crystals?
Answer: all types of crystals not only emit energy but also absorb energy. These are not always desirable energies. Especially protective stones like tourmaline, shungite, rock crystal, etc. can eventually become energetically contaminated, similar to a car that is never washed. It may just sit around but still gets dirty. In the case of crystals, however, this is not an optical flaw but a quality defect that can be easily remedied by cleaning your crystals.
What methods are used to clean crystals?
This is not an exhaustive list.
Simple
Running water
Hold crystals under running water for some time. Ideally, use Pen-Yang® energised water.
If you have a stream or river nearby, you can also place the crystals there for some time.
Natural
Sunlight
Place the crystals directly in sunlight for a few hours. It is important that they are not behind glass panes but directly outside under the open sky.
Proven
Healthy earth
Crystals can also lie on/in healthy earth for a day or longer. Preferably untouched patches of earth where no air traffic occurs are suitable.
Advanced
Smudging
Those familiar with smudging ceremonies can also use this to clean the crystals. It is important, depending on the wood, resin, or other substances used, that they suit the crystal well, so it is especially for experienced users.
Professional level
Energetic cleaning
Deep cleaning can be achieved through energetic methods. It is certainly more demanding at the beginning, but later very simple. Here, one should be instructed by experienced users. The first three methods with water, earth, and light are simpler.
Special
Pen-Yang® method
This can be considered the royal class of cleaning, as gemstones can be made insensitive in the long term without changing the stone itself or its structure. The principle here is to restore the original, natural order of the stone on all levels. Since no other manufacturer covers the electrical level, this can be considered a novelty. However, the company does not offer crystal cleaning and only applies it to its own gemstone necklaces.
How do I know that my crystals need cleaning?
Not only crystals but also necklaces, rosaries, crosses, and other special items should be cleaned regularly.
You can tell by the fact that the items feel unusual to unpleasant.
In the case of "sacred" items like rosaries, it may be that the supplicant notices that their prayers are no longer "heard".
Those who can test with pendulums, single-hand rods, or kinesiology can quickly get feedback on whether an item or crystal may need cleaning.
Which method for cleaning crystals is the best?
The simplest method is under running water.
The three methods described above: water, earth, light are easy to implement, proven, and bring the desired effect. Which method is best depends on one's feeling, the possibilities, and the items to be cleaned.
