News and information from the world of NatraSan, plus some of the science and research behind the products.

How often should you clean…?

If you can handle learning about the germs you may encounter in your home, carry on reading. If the mere mention of a bed bug will give you the heebie-jeebies, may we suggest you learn about the germ destroying power of NatraSan by reading one of our other blogs.

Although you may have a regular cleaning routine, there are items that perhaps you do not give enough attention to, which allows germs and bugs to fester. From the necklace you wear every day to the mattress you sleep on every night; how often should you be cleaning these everyday items?


For items that sit so closely to the skin, many people do not give a second thought to the germs that could harbour in earrings, necklaces and rings. A 2020 study by jewellery and watch seller Est1897 analysed the bacteria that collects on jewellery by swabbing the underneath of rings and watches, and the backs of earrings. Scarily, the study found that 23,000 growths of bacteria can manifest on jewellery in a single week.

The study highlighted that without weekly cleaning, germs can grow on your jewellery at an alarming rate. These bacteria could cause skin irritations or infections. Cleaning with warm water and gentle soap will do the job, but as NatraSan has been proven to kill 99.9999% of germs in seconds, and contains no damaging chemicals or alcohols, it is safe to spray on jewellery.

The fridge

Every time you add groceries to your fridge, new germs are let loose – in most cases these are harmless. Although you may think the temperature would stop germs from spreading, there are certain forms of bacteria that thrive in cold spaces. An investigation by Which? found that out of 10 fridges it analysed, all had some forms of bacteria, but seven contained high levels.

Remove everything and give your fridge a deep clean – by this we mean making sure you get into those shelf crevices and corners – every three or four months, but as bacteria can spread quickly, it is vital to wipe away small spills straight away. Make sure you also remove any food that is on the verge of turning rotten before it has a chance to spread bacteria.


Even during the winter months our bodies make approximately half a litre of sweat and shed just under a gram of skin every night. This means your mattress is a haven for bacteria, bed bugs and dust mites – in fact, your mattress is home to approximately two million dust mites.
You will never be able to get rid of all these bugs, but it does highlight how regular mattress cleaning is a must. It is recommended to give your mattress a clean at the beginning of every season, which involves vacuuming to remove dead skin cells and bugs, and using an anti-bacterial spray, such as NatraSan. As NatraSan comes in a simple to use spray bottle, it is also easy to regularly give your mattress a spray between vacuuming.


If you have family members who you are constantly asking to pick up their damp towel from the floor, advise them that as soon as it is dropped bacteria and germs will start to grow – then ask them if they would like to use that towel next time they wash!

You will not be able to keep towels 100% germ free, but as pesky pathogens thrive in warm and damp conditions, how you treat your towels can aid the unwanted spread. Ensure towels are fully left to dry between uses, wash them every three to four uses (except hand towels which should be changed every three to four days) and do not share used towels between family members.

NatraSan is completely safe to use on skin, meaning it can be used as a disinfectant to sanitise hard and soft surfaces, and used as an antiseptic. Purchase it from our online shop, or by calling 0800 707 6883 to place a telephone order.
