If I m walking with a cup of tea in hand, I ll trip and spill it. If there s a glass of wine within armspan, I ll knock it over. Not surprisingly, I m pretty much constantly trying to remedy one sort of stain or another. Even if you re fortunate enough not to be a mess-magnet, however, you re sure to find a stain on your new dining chair, or white carpet, or good table linens at some point or another. Bad idea it ll only serve to set it further.
Hot water can actually set some stains.
When in doubt, use cold water. W ork from the outside of the stain towards the center.
