Infection is the number one worry and should supercede all other concerns. Infection can increase the time needed for healing and even cause life-threatening complications. Also, because our disease is immune-stimulated, infections might lead to more skin activity. Keep the wounds clean. Wounds should be cleaned once or twice a day.
Water is the absolute minimum, but a diluted bleach and water mix is suggested.
Do not use harsh cleansers or iodine, and do not scrub too hard. All of these can cause more damage. Bathing and whirlpool baths are best. Soaking helps remove debris, scabs and dead skin. Ointments and creams.
