I experienced similar problem before. The easier way is to apply dish soap to the stained area before putting it into the washing machine. Wash the clothes with laundry detergent as usual. The grease stains will be removed after the wash.

You mean only grease stains but not coffee or dark tea stains?

[Francis]

Yes. Washing liquid can take away grease stains but not coffee or tea stains. For coffee or tea stains, you need to apply those stain remover with Reactive Oxygen Species (ROS).

You can try using other household items like vinegar, baking soda, or hydrogen peroxide. These can be effective at removing coffee and tea stains, but it’s important to spot test them on a small, inconspicuous area of the fabric first to ensure they don’t cause any damage or discoloration.

I tried vinegar, baking soda, hydrogen peroxide and ROS, I found that ROS is the most effective way to clean coffee, tea and curry stains within 30 seconds. A bottle of 500g ROS powder costs around HK$20 and it can be used for few years.
