- Chemical cleaning of tips, but I guess that if you need chemicals you might as well use new tips
also, pipette tips DO survive autoclaving, so after rinsing off the alconox with distilled water you can autoclave them in their box.
Many pipette companies will send you free samples of their tips in an autoclavable box, just ask them! If you are going to reuse tips then that one sample box should last you a good long time.

The best way to get rid of any organic contamination is using sulfochromic acid.
Sodium ascorbate or good old fashion vitamin c will help the body
convert hex chromium its harmless version. As an aside ;-) Sodium
ascorbate drips are what we use in the hospital for hex chromium
poisoning
