How do you flush the bathroom? Hopefully it wouldn’t be an excessive amount of to presume that, after ending up essential rest room enterprise, you find a button or deal with and press it. However, in response to analysis, the reply is likely to be extra sophisticated. By now we’re all nicely conscious of the truth that, if bogs are a breeding floor for micro organism, the toilet is their epicentre. On common, a rest room basin incorporates 3.2 million micro organism per square-inch, rivalled solely by the toothbrush holder. Once we flush, we run the chance of spreading these micro organism across the room, and probably throughout ourselves, too.
For many years, debates over how we do our responsibility – or, extra particularly, what we do afterwards – have divided nations, rearing up as soon as extra earlier this week. Does flushing a lidless rest room – and exposing ourselves to a “plume” of microscopic particles – make us sick, for instance? And do you flush public bathrooms utilizing your toes, as one 2013 survey requested? (Two-thirds of American respondents answered that sure, they do. A thought to ponder.)
So, how will we settle the best (and improper) strategy to flush a rest room? Ann Russell, creator of How To Clear Every part and TikTok’s favorite cleansing Auntie weighs in.


Ought to I at all times flush with the lid down?
“Primarily, sure – particularly while you’ve had a poo,” Russell says, “as a result of the flush can spray very high-quality particles and bathroom water throughout your rest room.” A 2022 world evaluation discovered that contaminated aerosol particles can journey so far as 1.5 metres away when the bathroom is flushed and linger for as much as six hours; the distinction within the quantity of micro organism unfold when flushing with the lid up versus down is, in response to a examine from 2011, almost 12-fold. “It’s greatest follow – although, let’s be sincere right here, it’s not going to kill you if you happen to don’t.”
What if my toothbrush will get contaminated?
“Once more,” says Russell, “it’s greatest to attempt to verify the toilet lid is closed to cease your toothbrush, or anything, getting contaminated, however I’ve but to listen to of anybody being made in poor health by their toothbrush.” That’s regardless of your toothbrush internet hosting as many 1.2 million micro organism to start with. “There are individuals who will say that it’s disgusting [if you expose your toothbrush to a flushing loo] however it’s most likely not going to do you any actual hurt.”
Is there something I ought to keep away from chucking down the toilet?
Sure, mainly something besides rest room paper, says Russell. “Bathroom paper is particularly made to disintegrate in a short time in water, and designed to not block up our pipe work. Which is why I don’t like folks utilizing issues similar to kitchen towels. A kitchen towel is designed to have what’s known as ‘moist energy’ in order that while you wipe your kitchen counter, it holds collectively. Something that’s not lavatory roll or human waste ought to by no means go down a rest room.”
When ought to I keep away from flushing?
Briefly, it’s as much as every family – if you happen to’ve simply had a wee then there’s no actual must flush each time if the lid is saved down, says Russell. And there are compelling environmental causes to abstain when attainable, not least as a result of most wastewater created by flush bathrooms (greater than 80% worldwide) goes immediately again into the setting with no therapy. There could also be different causes, too: “I stay in a really small, compact home and the cistern for our lavatory is behind the panelling on the foot of my mattress, so we now have a strict rule that no one flushes the bathroom after I’ve gone to mattress,” says Russell.
“This yr has been a very clear instance of the difficulty that local weather change is inflicting; our meals manufacturing is more likely to be massively affected. That signifies that, whereas proper now we expect we stay in a moist nation, the place there’s numerous rain, there’ll come a time when we have to divert water that we’re profligately flushing down loos to assist our meals develop.”


So it modifications if you happen to stay in a hotter or colder local weather?
“Sure, some issues change,” says Russell. “Take showering: if you happen to’re in Finland or within the UK when it’s chilly, you most likely don’t must bathe fairly as typically as if you happen to’re in, for instance, the southern states of America. Micro organism goes to develop faster within the heat, so that you’d be extra more likely to must flush extra, and maybe use extra bleach.”
Bleach is a vital for a recent flush, then?
“No. In smooth water areas, bleach is ok to scrub bathrooms, however in onerous water areas, you must keep away from all of it collectively. In onerous water areas you want a rest room cleaner with a limescale remover – however used along with bleach, that may launch chloramine gasoline.” Russell has realized from expertise. “I did it as soon as: an aged gentleman [whose house I was cleaning] put a little bit of bleach down the loos so they’d be hygienic for summer season. The very first thing I did was put Harpic down and inhale the gasoline – he thought he may need to name an ambulance; I used to be inexperienced, I might hardly breathe. I needed to sit exterior for half an hour.”
Does it matter how ceaselessly you clear the toilet?
“That, once more, will depend on your loved ones. If it’s simply you, otherwise you and one other grownup, then a couple of times every week is ok. For those who’ve obtained youthful youngsters then most likely eight occasions a day.”
By no means use wipes: “Use rest room paper, or a material that may go in a sanitising wash as quickly as you’ve completed cleansing.”
