The answer to this question will depend on how you intend to utilize the tubes.
If you are working with solutions that you intend to use in an aquarium you may not want to use any detergents or chemicals when cleaning them.
For life science experiments, after you have added 10% bleach to kill any pathogens in the tube you may use a powdered detergent like Alconox or Sparkleen which is suitable for most glassware. For the first wash using your cleanser of choice in warm tap water. Next rinse the tubes thoroughly in tap water. After this do an additional rinse in distilled water. Sonicating baths are also helpful in cleaning glassware.
If there is agar, agarose or some saturated chemical solution in the tube you should heat it first so that you can more easily dispose the contents.
For especially stubborn stains as a last resort you could purchase a chromic-sulfuric acid labware cleaning solution (but these cleansers are carcinogenic).
