There are several ways to clean your colon. From non-intrisive ways like taking supplements and teas to having an enema or a colonic irrogation, getting rid of buildup along your gastro-instestinal tract isn't the issue; you just have to decide how. Choosing a colon cleansing method is a personal choice; it has a lot to do with preferences, lifestyle, and financial solvency.
In the realm of relatively intrusive colon cleanse procedure, a patient is left with two choices: either do it yourself or have someone else do it for you. Should you buy home colonic unit kits or should you go to a clinic that has high end colonic equipment? How do you compare one from the other?
If you're the DIY type and you've had some colon cleaning experience, you could opt to get a home colonic kit. Alhough they fail in comparison to olonic equipment in clinics, the strong point of doing it yourself is that the cost isn't so high and you can do it in the privacy of your own home. However, you have to really know what you're doing since you'd be on your own and would be (more likely) doing the procedure without assistance.
If you're not a risk-taker, then you're better of having colonic equipment draining your colon of toxins inside a clinic. This option provides you with the comfort of having a licensed colon therapist do the procedure for you but you may need to shell out a bit more money for this.
