Nicely done!
An alternative to soap that I've had good results with: Tippex / Snopaque / typist's correction fluid (does anyone really use tripewriters any more?), also useful to stop solder or braze from spreading where you don't want it - the old solvent-based stuff was better than the water-based, but it still works now it's been elfin safetied...
