The Best Buy washing-up liquid that costs less than £1

Choose one of the three Best Buy washing-up liquids revealed in our latest tests and you’ll breeze through the washing-up after festive feasts – and you could save money, too. It’s the perfect time of year for big gatherings of friends and family, but once the crowds disperse, the task of scrubbing and scraping your way through piles of plates begins. Whether you’ve used five roasting tins for a show-stopping recipe, or Christmas revellers have used up every glass in the house, the best washing-up liquids will make light work of the challenge.

In our washing-up liquid tests, the very best clean up to twice as many plates as the worst-scoring options. We’ve tested 12 popular washing-up liquids from big brands and major supermarkets – three triumphed as Best Buys and, weight for weight, one of our Best Buys cost less than half the price of another. Want to find out which washing-up liquids are best – and best value for money?

Don’t pay more than you need to

Washing-up liquid probably isn’t the priciest item on your shopping list, but you can still save money without compromising on cleaning power. Our tests revealed one great value Best Buy washing-up liquid which costs less than GBP1 per bottle – that’s less that a third of the price of the most expensive option (per 100ml). Plus, Best Buy washing-up liquids can power through more grimy plates than others, so you’ll buy fewer bottles in the long run.

Ever splashed out for ‘premium’ options? We found one washing-up liquid that did just as well as its ‘premium’ counterpart, so you could be paying for ‘extra power’ that isn’t really there. Read all of our washing-up liquid reviews[2] to find out which it was.

Plus, our tests also revealed four Don’t Buy washing up liquids[3] that you might be best to avoid.

New, tough tests

Anyone who has tackled a cheesy lasagne dish or a gravy-encrusted roasting tin will know that baked-on fat is the most difficult foodstuff to wash off by hand. In 2015, we added a new ‘tough grease’ element to our washing-up liquid tests that revealed big differences between products. This year, we’ve enhanced this part of the test to make it even more realistic.

First, we bake tough grease into a metal tile. Then, we wipe it with even strokes of a sponge containing each washing-up liquid and count how many strokes it takes for all the baked-on grease to be completely removed. The results really separated the best from the rest – one standout performer cleared all the grease in just seven swipes, while the worst hadn’t shifted it after 100 strokes.

Our tests also measure how well each washing-up liquid removes lighter fat and grease, and how long the foam lasts when you’re cleaning everyday grime. That means that the washing-up liquids that score top marks are good all-round choices, while those that score poorly will leave you using extra elbow grease. For all the details on our rigorous testing process, find out how we test washing-up liquid[4].

Black Friday: are the deals real?

Shoppers spent a massive GBP1.4bn online on Black Friday – up some 11.7% on last year, according to the online retail trade body IMRG. But that doesn’t mean that all the Black Friday deals available were good value for money.

Our investigations have consistently found evidence of shops exaggerating and bending the rules on special offers to make them look better than they actually are.

In fact, our Black Friday deals investigation[2] found that up to 60% of Black Friday deals may not be the rock-bottom prices you’d expect.

If you’re planning your Christmas shopping or thinking of hitting the Boxing Day and January sales, make sure you know how to check if a special offer deal is genuine[3].

UK households waste 7.3 million tonnes of food a year

Roughly 4.4m tonnes of the food wasted in the UK annually is avoidable, and 2m tonnes of this is as a result of food not being used in time. A third of this is because of confusion around the existing date labels, according to new research by sustainability organisation WRAP (Waste & Resources Action Programme). Many people are unsure about the difference between ‘use by’ and ‘best before’ labels and how to best store their food, which can lead to food being unnecessarily thrown away.

According to WRAP, its recommended changes to labels could help cut around 350,000 tonnes of food waste a year by 2025. It could also save shoppers around GBP1bn a year. Your fridge is also an important factor in keeping your food fresh – if it’s slow to chill, or doesn’t keep a constant temperature, your food won’t keep as long.

If your current fridge freezer isn’t up to scratch, find a model that will keep your food at its best for longer with our fridge freezer reviews[1].

‘Use by’, ‘best before’ and ‘display until’ labels explained

Generally, a ‘use by’ date is about safety. It’s found on food that could be harmful if eaten beyond this date, such as fresh meat, fresh fish and packed salads. ‘Best before’ dates, on the other hand, are about quality.

They’re found on longer-life food, such as cereals, bread and canned foods. While the food may not be at its best quality after this date, it’s not unsafe to eat. However, there have been some cases where a ‘use by’ date has been used, such as on hard cheeses and pasteurised juices, even though eating the food beyond the date is safe.

Under new guidance set out by WRAP, these products, as well as others where there is no safety issue, will now carry a ‘best before’ date instead. While ‘use by’ and ‘best before’ dates are required by law, ‘display until’ labels are not. They are often used by shops to help staff know when to keep food on the shelves until, and to rotate stock, so that food with imminent dates are stacked to the front.

New food labelling

To help clear up confusion, WRAP has recommended that manufacturers and retailers simplify date labels by getting rid of the ‘display until’ date.

In addition, it’s suggesting that people are given more time to consume a product once it has been opened. It’s also encouraging the use of the ‘snowflake’ symbol (above), to highlight which products can be frozen, alongside instructions on when to freeze. Lastly, a new ‘little blue fridge’ logo has been introduced to signpost which foods should be chilled, or when storing in the fridge is beneficial to prolonging a item’s life.

Follow our simple tips to keep your food fresher[2] for longer in your fridge freezer.

Food storage: what to do

Another major cause of food waste is food not being stored correctly. Storing food in the fridge can add an average of three days to its life and save households money by cutting waste. As well as following the correct advice on your food, it’s important that you keep your:

  • fridge temperature between 0?C and 5?C
  • your freezer between -18?C and -20?C.

Food should also be stored on the correct shelves.

For example, higher shelves in your fridge and shelves in the door will be a higher temperature than lower shelves. Therefore, it’s better to store:

  • fresh meat and fish on the lower shelf;
  • condiments on the top shelf;
  • dairy, leftovers and ready-to-eat foods in the middle.

As part of our thorough fridge freezer testing, we scrutinise the time each appliance takes to chill and freeze, as well as whether the thermostats are accurate. We’ve found that some appliances chill faster than others and are therefore better at keeping your food fresh and retaining nutrients, and others which do a poor job at cooling your food.

Find out which are the most impressive by taking a look at our Best Buy fridge freezer reviews[3].
