i've always used a 10-15% solution. when i helped out during the ike clean up we were using a heavier concentration ( i think about 30-40% ) but we were using respirators because of the fumes. just do it outdoors or a very well ventilated place and DO NOT mix bleach and ammonia. rather toxic. good luck.
