Q. How do I banish yellow nail stains?
A. If you love that purple polish but it leaves your nails a nicotine-y shade, manicurist Renée Rainbird suggests squeezing a lemon into half a cup of water, then soaking hands in it for up to five minutes. ‘An alternative, good for more stubborn stains, is denture cleaning tablets; dissolve two in a teacup of water and soak. Scrub your nails with a toothbrush or nail brush and your nails should be gleaming.’
