An interior stylist has shared her helpful hack for cleaning stainless steel water bottles and removing any built up mould from inside.

Anita Birges, from Sydney, says people would be shocked to learn how much mould builds up inside the bottles and it only takes a couple of household items to eliminate the grime.

She first begins by pouring one third of a cup of uncooked rice into a stainless steel water bottle.

Next she squeezes only a small amount of dishwashing liquid into the bottle full of uncooked rice.

Anita tops the rice and dishwashing liquid with half a cup of water and then screws the stainless steel water bottle lid on tightly.

She then shakes up the water bottle full of rice and soap thoroughly to eliminate the mouldy interior.

Once the bottle has been shook well she pours the rice, water and dishwashing mixture out of the bottle and over a sieve into the sink

'Thank you for sharing this, I just chucked mine out if they got mouldy,' a woman said on Instagram.
