One Mrs Hinch fan wrote: “Bicarbonate soda will get rid of smell – sprinkle on the areas once clean and leave to dry then hoover off.”
Another person commented: “Bicarbonate of soda – sprinkle liberally over the area, leave for as long as you can then hoover up. Great for absorbing smells.”
Another person agreed, adding: “Bicarbonate – clean up as much as you can, then sprinkle bicarbonate and leave as long as you can until dry, then hoover up. My grandson was sick in my car and I did this and no smell since.”
One person suggested adding washing powder and vinegar to the mix. They said: “Wash with biological washing powder and a splash of white vinegar and water, then when dry, baking soda left as long as possible.”
