We changed from Persil non-bio to Ariel bio and have much better results, nappies are clean and fresh and haven't had to strip since I've been using it. I was reluctant to go down the bio route as I'd tried Bold before and that had made me itch and given Isaiah a red bum, but I know think that's probably more to do with high levels of perfumes in Bold.
I also find it keeps the clothes soft, I don't use softener anymore, just 1/2 tablet of ariel. A box lasts me ages!!
My clothes are also much cleaner so it's better at removing stains all round and saves me having to do multiple washes to get things clean.
