Washing mixture recommendation

[cwarrior 14]

Need to wash a house next week. New construction. All painted wood. Mostly saw dust, dirt, and a very few spots of mildew. What chemical do you recommend for this job? Would you just rinse the dusty areas with water? I need something to buy locally for time purposes.

Thanks!

simple cherry and 1 gal of 6% should do the trick
