Anyone tried putting filters in oven (100-120 degrees) to melt the grease out? Just read it on a website - wouldn't the plastic bit you use to fix it back into place melt too? Really don't want to wreck them at £40 quid a pop! TIA.
I soaked mine in the sink with a half a cup of soda crystals and two kettles of boiling water, for 20 mins. Worked a charm! Mine were revolting - I don't think they'd been cleaned for 5 years by the previous tenants.
