What face wash should I use while using Tazorac? My derm gave me Taz .5 & Taz .1. Taz .5 doesn't control my oily skin/breakouts.

She told me to use the Taz.1 nightly & switch between Taz .5 if my skin became dry. Both of them are gels. I am using clindamycin solution 1% 2X a day, washing my face with 2% salicylic acid face at night only, but the SA wash is too harsh to use while using the Tazorac. Should I just stick to using Purpose cleanser 2X day or is there a medicated/anti-bacterial face wash that I can use only at night that won't irritate my skin. I have used Taz for 4 wks now and I am still breaking out.
