I don't have a favorite.
My least favorite is specifically washing pots and pans. I haven't figured out a better way to wash them in the sink. I don't think there is an easier way. The water gets everywhere and I don't like that. I get my shirts a little soaked from it. And sweeping the living room carpet. We don't have a good vacuum cleaner here anymore. The one that is here is pointless to use cause you have to charge it before using it and the charge doesn't even last 2 minutes. I think it was a ripoff. So sweeping it takes awhile and I don't have all the time for sweeping all the dirt out of the carpet.
