Why Using the Right Amount Matters
Using too much detergent is a common mistake that can actually make your clothes less clean and damage your washing machine over time.
- Too much detergent: Causes residue buildup, odors, and can damage HE machines
- Too little detergent: Clothes don't get clean, bacteria can build up
- HE machines: Use 50% less detergent due to low water usage
- Hard water: Requires more detergent to overcome minerals
Tip: Most people use 2-3x more detergent than needed. Start with the recommended amount and adjust based on results.
