I clean my brushes regularly, but would love to have something that could be used daily to removes light traces of make-up in between applications of different color shadows etc.

I second this. I use regular old soap/shampoo and water to clean my brushes once a week but it doesn't feel like enough to me and I hear using water to clean brushes is a no-no.. hmm..

Thirded, please.

I'd love a daily brush cleaner spray with good ingredients, please. The ones from Sephora and other labels I've checked contain a lot of what seems to be unnecessary chemicals to me... and I'm afraid of doing more harm to my skin by using them on my brushes.

I currently wash all my brushes after each usage and then sanitise them with rubbing alcohol, which can get pretty time-consuming. But better that than to have breakouts from unclean brushes.
