I've recently bought myself some Winsor and Newton Series 7 Kolinsky Sable brushes, and while I'm thrilled with the quality of the brushes (a #1 and a #2/0), I'm terrified of damaging them when I need to clean them. Mu original brushes, a set of Citadel ones, were decent enough, but finally bit the dust after heavy use and inexperienced cleaning. So, resolving to take care of my new brushes, having watched a brush cleaning video by Les Bursley, I bought myself some of 'The Masters Brush Cleaner and Preserver. My problem however, is that Les only detailed how to clean a drybrush using a more vigorous method suited to a drybrush. While the technique and video was useful, I can't use this vigorous technique on a fine detail brush without ruining it!
So, here's my current method for cleaning my new brushes:
1. Add a few drops of water to Masters brush soap and gather suds on my finger.
2. Massage suds into brush using a circular motion between thumb and index finger.
3. Leave brush to sit for a few minutes.
4. Rinse
5.Massage more suds into brush.
6. 'Flick' brush across finger mimicking painting strokes.
7. Rinse
So my question is - am I doing this right - or will I damage my brush/ineffectively clean it using this method?
I should clarify that I rinse all the heavy paint deposits from my brush regularly during painting, I never leave paint to dry on the brush if I get up and go somewhere else (unlike my poor old citadel ones!

), but only once I put away all my painting gear at the end of a session do I go through the above method.
Any help would be appreciated.
