Plasmid contamination from pipettors

[Michael W. Thompson]

Does anyone out there know of a good procedure to decontaminate
pipettor barrels for use in RT-PCR experiments and likewise?  A big
problem in our lab is that since we have been working so extensively
with specific cDNAs, when we try to run an experiment such as RT-PCR
which is sensitive to contamination, there are multiple bands in all
samples.
	Anyone?
