I can't say I've tried many different types or really done an investigation into different types, so I'm probably a bit clueless, but I often use Earth Choice, which I just get from Coles- and I've really liked all their products.

I dooo make some of my own sprays.....SO easy. Seriously, I made two different ones before Peter was born (he is now 8 months) and I use them for everything and they are still going strong. You do, however, need to like the smell of vinegar and tea tree oil!!
