Just after your best tips really.
I bought a cheap ikea one about 10 years ago which has been through the washing machine many time and is starting to look worse for wear now, but I was bought a lovely John Lewis one which has not been washed yet so I want to do right by it 
I wouldn't usually use fabric conditioner on it (or can I?) but could I use some Zoflora to give it a scent boost or will this ruin it? I have a specialist wool cleaner to use, although someone told me on a thread about Stardrops I started that they get good results with that.
Also I stupidly spilled red candle was on it last year so if anyone has any tips on how to get that out I would be extra grateful!
