I need to know how to remove oily stains on my pillowcases, this is caused by my husbands bald head!!?
Washing up liquid is designed to remove grease from dishes. shampoo is designed to remove grease from hair. Rub some onto the pillowcases before each wash and this should sort out the problem. Vanish and the stain solvents mentioned will also work but I always prefer to start with milder products because they are kinder to the skin and to the environment.
