洗碗时不要浪费水

Dishwasher v hand 洗ing, which uses less water? Which option is more eco-friendly?

在您和我继续进行烹饪和清洁的日常工作时,德国波恩大学进行了一项研究,以最终并永久地回答这个问题。

答案?

这取决于。

The study found, on average, 洗ing a load of dishes by hand (12 place settings), used 关于 103 litres of water (and an average of 2.5Wh of energy for hot water heating).

怎么样 每个参与者’s hand-washed made all the difference. Some 洗ers used as little as 30 litres of water, others used as much as 450 litres!

参与者之间的水消耗,技术,能力和清洁度差异很大。

但是,相比之下,(机械类型的)洗碗机每负载使用15至30升水(1–2kWh的能量),具体取决于其效率[资源]。

Even the most efficient hand 洗er in the study isn’t as efficient as a good dishwasher.

So is hand 洗ing dishes a thing of the past?

We 洗ed dishes by hand for 35 years. But a couple of years ago, we purchased a dishwasher and while I’我不相信它比我使用的水少,它无疑使生活更轻松。 

但是仍然存在水问题。

水安全是一个重要问题。澳大利亚本世纪已经发生了两次严重干旱,’预计会变得更糟。

Despite what the study says, you don’t need a lot of water to hand 洗 the dishes.

In fact, I think hand 洗ers can do just as well or better than 15 litres a load.

您的平均水槽可容纳约20升水。在半满的水槽中洗净,您仅需使用约10升的水即可。加一点额外的水冲洗,就可以用12升或更少的水洗碗。

如果你 洗 up twice a day, that’s still only 22 litres of water, comparable to a standard dishwasher.

这里有一些节水技巧,可让您的碗盘起泡干净。

如何用最少的水手工洗碗

When I was a kid, dishwashing was a skill we learned in Brownies at camp where there was only tank water and we had to 洗 up in basins. 如果你’再用坦克的水,你’我比我更清楚节约用水的重要性。

这些步骤是我’ve found to be most water-efficient when it comes to hand 洗ing dishes.

1.在食物变干之前,用硅胶刮刀刮擦盘子

硅胶刮铲是您在厨房里最好的节俭朋友之一。从罐子中刮出最后的果酱,从锅中刮出最后的土豆泥,最后一点点的煎饼面糊(嗯,酥脆的运球碎屑),用它把饭后的盘子刮干净。

坦白说,我一直是每个人都要完成盘子上所有食物的最后一步(而且可能会有舔舔盘子的遗传特征,从母亲传给女儿)。

但是孩子们并不总是能完成所给的一切。而且老公有一个习惯,总是在盘子上留一些东西。一粒豌豆。一点鸡。叉子上剩下一堆土豆泥了……

刮开它,直到它结硬并粘上,然后您’ll make dishwashing oo 容易得多。 

如果您的盘子上的食物变得干硬,然后才有机会照看它们,请将它们在冲洗前的水中浸泡一两分钟……

2.在几厘米的水中预冲洗餐具

碗碟需要清洁的水才能得到正确的清洁,因此,最好先将餐具清洗干净。

节约用水 一丁点 水槽或脸盆中只有几厘米的热水,然后用洗碗刷轻轻擦洗碗碟,以擦去残留的食物。

漂洗结束时,这些水可能会变得很泥泞,但是因为这只是漂洗前的阶段,所以可以。

As with the 洗ing up, rinse the cleanest stuff first.

如果你 use a basin or pot instead of the sink, you can pour this water out onto the garden.

3.预先浸泡炊具以清除顽固污渍

While this isn’t strictly 关于 saving water, it 确实 save labour: cooked on food is a pain to 洗 off.

Make it easy by sprinkling the bottom of your baking pan or fry pan with a little 洗ing soda (same as is in the 自制洗衣皂),然后倒入少许热水-刚好覆盖底部。离开浸泡过夜。

The next morning, give the pan a quick once over with a dish brush, pour the dirty water out and you’re ready to 洗 the pan, without all the scrubbing, with your next load of dishes.

4. 唐’t fill the sink to 洗 the dishes

All you need to start 洗ing the dishes is 水槽底部有几厘米的热水 和一些泡沫。水越热越好。使用手套,这样您就可以直接使用热水–这将使您的盘子闪闪发光。 

当你’重新等待自来水变热,不要’不要让水从水槽流下!将其保存在锅或水罐中,以用于饮用或烹饪。只需在冰箱中冷却即可。

另外,仅使用足够的泡沫清洁餐具。肥皂水过多意味着您需要更多的水才能冲洗碗碟。 

首先清洗干净的小东西,然后……

4.用热水冲洗到同一水槽中

用热水将肥皂水冲洗掉,直接倒入水槽或脸盆中’re using to 洗 the dishes.

这样,到了锅和较大的物品时,您将只有一半的水槽,而不是几厘米的水,足够大的水用于较大的物品。

或者,如果您有一个双盆水槽,则可以在第二个盆中放一点水,然后用它蘸水冲洗。

或者,这就是我妈妈的做法,在完成后,将一壶水倒在洗碗碟机上,以一次冲洗掉所有碟子上的泡沫。

5.将洗净的水倒入花园

如果你’ve used a large soup pot or basin to 洗 your dishes in, you can tip the water out onto the garden or lawn. This keeps your plants alive without hose watering, which is often banned during water restrictions. 

如果你 use your grey water on the garden, just be sure to choose a greywater safe dishwashing detergent. 

5.滴干

好的,滴干碟与节水无关,但是与节省时间有关!

While it’s possible to use as little or less water than a dishwasher when hand 洗ing dishes, there’s no getting around the fact that it 确实 花更多时间。

至少通过在碗架上滴干碗碟,您不需要做更多的工作。

Better yet, of course, is to delegate the job of 洗ing the dishes entirely.

顺便说一句,如果您有洗碗机,请关闭干燥设置并让餐具在洗碗机中滴干,以节省电源。只需打开门以保持气流。

Call it cognitive bias, but despite the study, I’m still not comfortable with the claim that dishwashers are more eco-friendly than hand 洗ing.

如果您不这样做,它们可能更节水’t take steps to minimise water when 洗ing. But a few frugal strategies will ensure you keep dishwashing water to a minimum.

  1. No dishwasher here either although sometimes I wish I had one. Over my life time I think I have kept at least 3 dishwashers out of landfill. These things do not last long and people seem to be replacing often. This is motivation enough not to buy one. I was taught to hand 洗 in my home economics class at high school. My approach follows the Brownie Guides approach you were taught. It irritates me to no end when I watch my DH fill the sink to the brim and when he seems to have no order to doing the job. I will be showing him your post!

  2. 请问?您是否曾经定期使用洗碗机?

    Sometimes we have gone without ours and I can honestly tell you, that hand 洗ing uses way more water to 洗 the same qty of dishes as the dishwasher. 那 is with me being careful and only filling the sink to what we need to. We are on tank water, so have to careful with what we use.

    I am of the opinion that unless you have done both (hand 洗ed and used a dishwasher) for a decent length of time, then you can’不能对其中任何一个发表评论(也要说那些只拥有所有使用过的洗碗机的人不应’真的对洗手发表评论ðŸ〜‰)。甚至我多年从事防洗碗小姐工作的MIL都来找他们,当她看到他们能做多少以及如何清洁某些餐具时。

    1. 嗨Astrid,

      很高兴听到论点的另一面。

      I’我过去曾住在有洗碗机的出租物业中。但是我没有’t used one for several years now. The consensus is certainly that dishwashers use less water, particularly the more recent ones. I just think hand 洗ing has an undeserved bad wrap of late.

    2. 是的,但是您不能否认他们破坏了您的好东西。当我拜访我的in妇或您称她为DIL的次数如此多次时,她对我说“Don’不要把它放在那里,否则会毁了它。”我看着褪色的杯子,盘子。刀柄,锅柄和许多其他东西已经得出结论,除非您想不断更新所有餐具,餐具和锅,否则就不要做。当您感到疲倦并有客人时,它们很棒,但实际上是每天。对不起,不适合我。

    3. 拥有洗碗机已有多年,又手洗过‘many years’我也可以肯定地说,我可以用比洗碗水少的水洗手。

      我们生活在一个相对偏远的地区,使用水箱水和化粪池,因此必须将油脂降至最低。我使用了一种类似日本浴原理的技术,’在您已经干净之前,不要进入浴缸。

      我们有一个双水槽。我将以前洗过的水留在一个水槽中,我每次使用时都会使用’饭后做饭或打扫卫生。我从板上刮下碎片(通常是堆肥),然后将板/锅等保持在空水槽上方,用刷子和另一个水槽中的脏水冲洗干净。‘wash’ the dish as clean as possible. (Very greasy pans get wiped out with newspaper first.) I then stack everything, for proper 洗ing once I have enough to make it worth while (usually once a day). When ready, I empty the bowl of dirty water (or put it on the garden if we’re in a drought) and put just enough hot water in the bowl (solar water heater) to give the already fairly clean glasses/dishes a proper 洗. I very lightly rinse over the 洗ing water (as above), so that by the time I’m 洗ing greasier pots/pans there’s more water. I use a 洗ing up bowl, because this way I can run cold water till the hot comes through and this either waters plants or goes into the dogs’ water bowl. All the dishes/cutlery/pots/pans get a very small rinse to remove any soap film but this uses very little water, and will be recycled for rinsing the next 洗. I can 洗 a fairly large load of dishes etc in no more than 10 litres of water, and they are really clean. I’我什至没有想过要回洗碗机。

      1. 嗨,薇薇安,

        Thank you for sharing how you 洗 dishes. It sounds super-efficient and water saving. Essential if you’依靠罐中的水或有水限制,但是我们所有人都应该做一些事,以节约尽可能多的水,尤其是在这次丛林大火时。一点点帮助。

        再次感谢。

  3. I use 2 liters per day max. All my water in both my sinks is collected by well fitted plastic containers, one on the left for rinsing, one on the right for 洗ing
    – The one on the right collects water throughout the day from rinsing hands, fruit, veg, the odd glass or mug, etc. I put the dirty dishes into it to soak throughout the day, and when I have the time or inclination, I 洗 them with a soapy cloth (no suds in this method, unless there are a lot of dishes) If I have to soak a big saucepan, I pour this water into it instead of tap water. When the 洗ing plastic container on the right is full, I take it to the garden or pour it down the sink if it is too dirty.
    – I rinse the dishes under a slow flow of tap water in the left plastic container. When the 洗ing plastic container on the right is emptied, I pour the collected rinsing water into it to start the whole process again
    –因此,平均而言,我每天要消耗掉大约2升水。
    Needless to say, I use an environmentally friendly 洗ing product so the water I poor into the garden 确实 not damage the plants. Which brings me to the point that dishwashing products tend to be very toxic, adding to the pollution accumulated by discarded dishwashers.

  4. I’我经常洗手,我先将所有脏盘子,盘子,杯子,杯子,餐具装满水槽,然后再洗手。加入洗碗液,然后加热水。然后,我喜欢让他们坐在那里放松或做其他事情。如果食物残渣变干,可能会成为问题的锅也要装满一点热水,然后放在一旁。

    When I come back a few hours later, the dishes are practically clean and so I just give them a quick wipe and rinse with water, and they are done. I then use the remaining water in the sink to deal with the pots. 唐e.

    I’我从来不想要洗碗机,除非我们有来访者’我面对着一堆碗菜。因此,我很快就会得到:),尽管我不太可能每天使用它。

  5. 我更喜欢手工洗碗,因为它减少了伤害。扁平餐具,玻璃杯和餐具会被刮擦,有时肥皂(我已经尝试过全部使用)会使某些颜色褪色。我有一套黑色处理的不锈钢餐具,必须更换,因为它们从Cascade中漂白了。我还有一些老式的东西,我不敢放在洗碗机里。因此,即使我的厨房里有洗碗机,我也很少使用。

  6. 只是读这个就不能’不要相信洗碗机要用多少水!我从来没有用过,今晚我发现自己要用3升的水完全清洁碗碟。
    我在澳大利亚内陆的一个农场长大– water was treated as more valuable than gold, especially our limited drinking water from a rain tank. I kept to my frugal ways when I moved to the city, and I still shudder when I see people wasting water by 洗ing their car on the driveway, for example.

  7. Hi Melissa I too 洗 my dishes by hand. I 洗 once a day and do what others do , also rinse in bowls. I only use a max of 10 litres , most times less. All of the water is for plants etc. I also shampoo my hair over laundry sink then bucket it out for a flush in the toilet. Likewise in the shower I have a bucket and use that for a toilet flush. I am going to buy your book because I am extremely budget conscious out of necessity. I enjoy reading the comments. ????????

    1. 嗨,凯,谢谢您的评论。

      It’很高兴听到您的节水方式。我们的淋浴间还有一个水桶,可以重复使用水。自撰写本文以来,我们已经购买了洗碗机。它也使用10升。虽然我喜欢便利,但我可以’t collect the water and reuse it like you can when you hand 洗!

  8. 非常感谢您撰写本文!我一直在寻找逐步指南,因为我只有一个隔间水槽,没有洗碗机。谢谢谢谢!
