Laundry detergent hack: We’ve been doing the washing wrong all this time –

Think you know all there is to know about laundry? Well, think again.

A new hack has gone viral on Facebook, revealing a little known fact about laundry detergent that most had absolutely no idea about.

While many use the lid or measuring cup that comes with your laundry detergent to simply measure out the liquid and pour it into your washing machine, it seems this is wrong.

It’s been suggested that you’re supposed to put the plastic lid or cup into the wash with your load, so all the detergent can be thoroughly rinsed from it.

It means your clothes get an accurate amount of detergent and it stops excess detergent and gunk from building up in your cup.

Then once the load is finished, just remove the perfectly clean cup for the next time you wash. Genius!
