Dreambly Wash + Dry Sheets (£11.25 for a pack of 40) may be one of the coolest household cleaning items I have ever come across. Just one sheet acts as all the following: detergent, stain remover, whitener, fabric softener, brightener, and antistatic. It is also completely biodegradable, is made of natural ingredients, and even disinfects your washer with each load.
