When it comes to doing laundry, knowing how much detergent to use can be a bit of a challenge. That’s because the amount of detergent you need will depend on the type and hardness of your water.

But with a bit of practice and trial and error, you’ll soon be able to dial in precisely the right amount every time. So why not get started today by having a go at doing your next load of laundry using only half as much soap as usual? You might be surprised at how well it works!

However, by carefully measuring your detergent and listening to your machine’s feedback, you can easily find the perfect balance between power and gentleness. With some experimentation, you can master the art of using laundry detergent for soft water and optimize your results every time!
