In a dirty kitchen, the often overlooked culprits are the damp areas. These spots are the ideal breeding grounds for bacteria such as E. coli and Salmonella. Our sponges, brushes, and dishcloths are kitchen cleaning implements that frequently come in contact with food particles, such as raw meat and vegetables, thus becoming perfect damp breeding zones. So, it is advisable to always start with the cleaning implements for a thorough, deep kitchen cleaning.

  • You may regularly put these brushes in the dishwasher to sanitise them. But make sure to check if they are dishwasher-safe.
  • Use bleach and water (1 teaspoon of bleach per quart) and soak the brushes in for a few minutes. Remember to rinse them thoroughly afterwards.


  • Wash the kitchen dishcloths in the washing machine using hot water and detergent. You may include a bleach cycle if the fabric can tolerate it for deep cleaning.
