Additionally, washing in cold water helps preserve the colors of your clothes and saves energy. **

To remove curry stains from clothing or fabric, start by scraping off any excess curry with a spoon or dull knife. Then, blot the stain with a clean cloth or paper towel to absorb as much of the curry as possible. Next, pre-treat the stain with a stain remover or a mixture of dish soap and water, and let it sit for a few minutes before laundering as usual. For stubborn stains, you may need to repeat the pre-treatment and laundering process. It's important to check the care label on the fabric for any specific instructions or restrictions before attempting to remove the curry stain. **

No, a henna tattoo does not come off immediately when washed off. Henna paste needs time to dry and stain the skin, so it typically needs to be left on for several hours before being washed off. After the paste is washed off, the henna design will continue to darken over the next 24-48 hours as it oxidizes, creating a long-lasting temporary tattoo. **
