Follow The Detergent Bottle Instructions
Follow the instructions printed on your detergent packaging. They’re there for a reason. Even if you double the quantity, it won’t have more anti-bacterial or cleaning qualities. You’ll just be wasting money by the load as a result of this.
Second, you could do more harm than good because detergents can alter the color and texture of your clothing, making it unlike how it was previously. So don’t experiment. Stick to the stated amounts and always follow the care instructions on the labels.
