Need to clean Unwanted "Fizz" from Audio

I interviewed someone outside and finished up with some unwanted noise.

I have Izotope RX2 and have been using it successfully to get rid of some bursts of low frequency wind noise using the Lasso Selection Tool with Spectral Repair, but I'm having trouble removing some continuous higher frequency "fizz" from the audio.

I've put a small sample here:

If any other Izotope users would care to have a go, and if successful, tell me how you did it, then I'll apply the same tactics to the rest of the audio.

Thanks for any assistance.

SpectraLayers Pro is just what you need. You can separate not only single tones but also harmonics, noises ect. You will be able even to remove birds' voices from your recording.
We use Spectralayers Pro and RX4. RX4 is better in quick removing noises. Spectralayers Pro is, in my opinion, better in surgical removing difficult, harmonics sounds.
Here you can find many tutorial vids:

If you only have RX2 you can still get an acceptable result using the DENOISE function. The "Simple" page is OK.

Make sure you use the Time Selection Tool [T] to select a place in the file where there is no speaking or breathing first (e.g. select all the time at the beginning of the example you posted before she speaks), then press "Learn" button on Denoise module.
Pick "D" for the 'Alogrithm' setting.
Then select the whole file before pressing "Preview" or "Process".
Experiment with settings of the Noise Reduction slider (around 10-12dB works well here). Similarly with the "Smoothing" slider (around 7.0 sounds good here).
Remember the more you remove noise the more unnatural the result - a little residual noise is still your friend!

Thank you ChristoC - just tried your recommended settings and it's a huge improvement - much appreciated.
