Yes, using too much laundry detergent can potentially ruin clothes. When too much detergent is used, it can leave a residue on clothes that can cause them to feel stiff and scratchy. The residue can also trap dirt and bacteria, making clothes look dingy and smell bad.
In addition, using too much detergent can cause the washing machine to have excess suds, which can lead to mechanical issues and affect the machine’s performance. This can result in a shorter lifespan for the washing machine.
To avoid these issues, it is important to follow the manufacturer’s instructions for the amount of detergent to use for each load of laundry. In general, using less detergent than the recommended amount is usually better than using too much. If you find that your clothes are still dirty after using the recommended amount of detergent, try pre-treating stains or using a different type of detergent rather than adding more detergent to the load.
