Washing and drying your hands after using the bathroom might seem like a simple, non-negotiable everyday task but, as it turns out, it’s something that an alarming amount of us skip over entirely.

A whopping 21 per cent - or one in five - Aussies believe that they don’t need to wash their hands every time they go to the loo according to research from Dyson and YouGov.

Er, why, you ask? Well,16 per cent of the 1,000 participants in the survey said they didn’t think that their hands got dirty every time they visited the toilet.

It appears we have the same opinion when it comes to drying our hands after giving them a clean, with a quarter of those surveyed saying that they don't need to dry them post-wash.

And even if they do get under them under the tap, one-third of Aussies end up wiping their wet hands on their clothes as there was no drying option - such as paper towels or a hand-dryer - available.

If you’re guilty of any of the above, you might want to clean up your act as your dirty deeds aren’t going unchecked according to the research, which comes in line with launch of the new Dyson Airblade 9kJ hand dryer.

Just under 90 per cent of Aussies said they’d witnessed their fellow public bathroom users bypass basic hygiene practices, with

More men (74 per cent) than women (68 per cent) revealed that they have seen someone leave a public loo without washing their hands, with those in their 60s and 70s on high alert for bad bathroom etiquette.

Indeed, 92 per cent of Baby Boomers reported seeing someone exit a public bathroom without washing or drying their hands, compared with a near-equal number of Millennials (86 per cent) and Gen X (87 per cent).
