My parents have a house built in the 50's- with a white/cream brick wall in the kitchen area. I would like to clean it, but don't know what to use. It's a rough texture. Does anyone know how I should clean it?

One of the best cleaning products I ever used is "Spray Nine"
Amazon.com: Permatex 26832 Spray Nine Multi-Purpose Cleaner and Disinfectant - 32 oz.: Automotive (http://www.amazon.com/Permatex-26832-Multi-Purpose-Cleaner-Disinfectant/dp/B0014COKYU/ref=sr_1_1?ie=UTF8&s=automotive&qid=1251432361&sr=8-1)

I use it to clean truck seats and kitchen and degrees my engines.
