Am I overreacting?

My husband and i both work full time and his hobby is detailing cars on the side. EVERY weekend he is detailing (even our cars) the problem is I’m stuck doing all the house work and unable to do any laundry because we have a well. During the week I am unable to do housework or laundry due to work hours. This weekend he had no cars scheduled so I was hoping to do the 4 loads of laundry we had. I ran downstairs to put it in and hes our washing our cars 😩😑. I asked if he could do it later after we cleaned the house and did some laundry and he said “I put my dishes in the dishwasher and there is some dust on the car” (car gets a complete detail weekly) Am I overreacting at being irritated?
