elimination of DNA from an RNA sample

[Stefi~]

Hi everyone.
I need to perform an RT-PCR but my DNase I doesn't clean my RNA sample from
contaminant DNA. I use glass-fiber based kit for extraction and I treat my
RNA sample with 1U of DNase I every ug of RNA.
Does it exist a kit that eliminates every trace of DNA contamination?
Thx very much.
