How to clean cooker extractor fans?

[krisskross]

I've tried hot soapy water and put them in the dishwasher and also dettol spray, but they still look and smell greasy

What can I do?

Stardrops from Wilko? It's cheap and great for a variety of jobs with different levels of dilution. i'd spray on a 50/50 solution and leave for an hour, then into the dishwasher.
HTH

Ooohhh thank you....what is it and whereabouts in wilko would I find it?

Thanks

No dishwasher here, so I soaked ours in the bath in a solution of hot water and soda crystals (found in laundry product aisle). It was horridly fascinating watching the globs of fat rising to the surface of the water. I rinsed them off with the shower and then soaked again in clean solution.

Thanks quietly, think we might have soda crystals so I'll try that, thanks

Here you go. Tesco sell it too.

Excellent thanks Sgt major

A biiiig thank you to quite quietly..... They are clean thanks to soda crystals!!! No scrubbing needed!
