Acne is not a sign of poor bodily hygiene. On the  contrary: too frequent cleansing of the skin with aggressive cleansing products can irritate the skin even more. Nevertheless, you should take care to cleanse your skin twice daily with a mild, nondehydrating facial cleanser in order to remove excess sebum, sweat and dead skin cells from the skin. One should, in any case, avoid "fiddling around" with your fingers on the acne symptoms.
