In order to function at their best, chakras should be clean, and active in appropriate proportions : overactive chakras will also favor health impairments, such as social anxiety.

Unclogging the seven main chakras is the road to developing one's full abilities, including some which are broadly used, and regarded by current science as "paranormal" - for example, the ability to locate water sources and underground currents. Used by many companies worldwide, yet difficult to explain and prove using our scientific models.

How to cleanse the chakra system

1) Identify which chakras are blocked.

This is the first step. It can be achieved through simple personality tests, which will highlight the areas of our spirit impacted by inappropriate chakra activity.
Online Chakra Test (since global changes in etheric activity have occurred, this test might now report seemingly overactive chakras in many cases). This test also recommends ways to then clean or open up one's chakras.

2) Once the clutters have been identified, they should be cleaned and balanced from the bottom up. Self-reflection, meditation, psychology can start the process of cleansing chakras.

I highly recommend, for example, the book "Secrets of the Cube" to induce self-awareness and help cleanse the third eye chakra.

3) Additional chants, physical practices like yoga, mudras (hand gestures) can further cleanse one's chakras and unlock the individual's full potential. As per this article. Mudras are a specific form of "acupressure", and work by putting extremities of the etheric body in contact, or favoring etheric activity through physical postures.

4) Finally, other personal techniques have been brought to our attention, such as : sports, creative writing, music, painting (highly recommended for people who have an overactive root chakra) - any approach to exploring connections between our spirit and our physical body will have an impact on the chakra system's global activity.

Chakra cleansing, and the perception of their activity (tingles for some people, heat for others, vibrations..) are deeply personal, and vary from one individual to another. Thus, these essential tips should be considered as generic guidelines. We recommend you to elaborate your own chakra cleansing method(s) based on these guidelines, by testing the approaches which naturally appeal to you, and selecting the most effective subset for your astral/physical bodies.
