During the pandemic, as people sought to protect themselves from Corona Virus, more and more products entered the market claiming to use Ultra Violet light to clean your belongings. These vary from UV wands and lamps, to phone boxes and UV baby bottle sterilisers. 
You may have seen them advertised online, claiming to kill 99% of viruses and bacteria.
But do they deliver, and are they worth it, compared to more traditional methods of cleaning like alcohol wipes, or soap and water...
That's what listeners Chris and Ben wanted to know. I'll be finding out by speaking to an expert in radiation safety Professor John O'Hagan at Loughborough University and Matt Knight, Product Testing Expert at the consumer group Which? Once again this series we’re testing and investigating your suggested wonder-products, so if you’ve seen an ad, trend or fad, and wonder if there’s any evidence to back up a claim, drop us an email to sliced.bread@bbc.co.uk or you can send us a voice note to our WhatsApp number: 07543 306807 PRESENTER: Greg Foot PRODUCER: Jay Unger

While Sliced Bread takes a break we serve up... Toast. A study of the spectacular failures of brands which had promised so much to consumers.     In each episode, the presenter and BBC business journalist, Sean Farrington, examines one big idea. What did it promise? Why did people back it? Why did they get burnt?   Some of the world's most successful businesses have also brought us some of the world's most remarkable failures. So, what led them to be toast? And what can we learn from their stories today?  Sean unpicks all the early optimism, hype and ambition. He learns about the tremendous success of a brand before hearing how it faltered, with help from expert commentators and people who were directly involved. How do they view things now and what, if anything, could have been done differently?  The self-made millionaire and serial entrepreneur, Sam White, is alongside him, analysing the missteps that changed a brand's fortunes and reaching her own, often instructive, conclusions.   From big tech to high street retail and, of course, food, Toast tackles the business ideas that, one way or another, ended up cooked.  Sliced Bread returns for a new batch of investigations in February. In the new series, Greg Foot will investigate more of the latest so-called wonder products to find out whether they really are the best thing since sliced bread. In the meantime, Toast is available in the Sliced Bread feed on BBC Sounds. Toast is a BBC Audio North production for BBC Radio 4.

Toast - Little Chef

This one's all about mushrooms - not so much your chestnut, button or portobellos from the supermarket, but more the likes of lion's mane, reishi and chaga. These much-feted fungi are claimed to offer all sorts of benefits, from relaxation to disease-fighting properties. We've had loads of questions about products containing them, particularly around mushroom coffee. Is there any evidence that it's better for you than your regular brew? Listener Leon is fond of it - and wants to know if there's any science to back up his inclination. To get him some answers, we hear from a registered nutritionist and a mycologist (fungi expert) who's just written a book all about medicinal mushrooms. So are they the best thing since Sliced Bread? If you’ve seen an ad, trend or wonder product promising to make you happier, healthier or greener and want to know how it stacks up, then email us: sliced.bread@bbc.co.uk or send a voice note to our WhatsApp number: 07543 306807 PRESENTER: GREG FOOT
