I'd sell the car. Long after the smell has gone you will still imagine that you can smell it. Or it might be like cat pee and the smell will come back in humid weather
That's what I'm worried about - that I'll smell it even if it's not there

Marydean I have some of the pet stuff here, says it uses bio-enzymatic technology so here's hoping thanks for the tip

Lissy we tried Glen 20 but I can still smell it - although only on that first day. Will keep it in mind cheers
