Make this the deep clean you do for the month and the other cleans should be easy, hose the house down, clean deep and hard and yes, hire a team to do it. Get everything looking spik and span and clean as you go.
And do not forget the skirting board. This is one of those areas in our homes that will often go amiss but it is more than the skirting board, it’s the last big clean before Christmas, so get on hands and knees and clean your skirting boards and floor boards and all the floors and window ledges… it should feel like take two of the deep clean, and you can hire someone to do this for you.
