? How to destroy DNA chemically (to reuse DNA columns)

In a previous article, djt2 at po.CWRU.Edu (Dennis J. Templeton) says:

I am confused.  Qiagen columns are DEAE anion exchangers and yet you say
they are similar to a silica column?

Second point: sounds like you are wasting time and effort and taking a
potentially hazardous (in time and money) risk in trying to re-use columns.
Qiagen columns are not *that* expensive.  Spend the extra money and sleep
well at night.  Sure as hell beats troubleshooting.
