As I understand things the soap removes an oily film that protects the virus and helps it enter human cells. Bit of a guess here, adding oil might replace the film or even make the virus stronger.

For a definitive answer try the World Health Organization they might have the answer.

Stay away from washing your hands in those four products, especially Benzene !

A longer explanation here, its not just the AA interactions that soap disrupts.:https://www.theguardian.com/commentisfree/2020/mar/12/science-soap-kills-coronavirus-alcohol-based-disinfectants

Despite advice from across the pond, don't drink it, dont inject it!

Castrol Cooledge used to carry the dead fish and tree symbols (the new stuff doesn't), so used neat may work.

I'm going to stick to soap / water and alcohol hand gel for now

Interesting Idea!

All I know is that soap and water does a cracking job.

One factor which is relevant to any answer is – What type of oil? The physical and chemical characteristics can both vary hugely, depending on whether you are looking at cutting oil or cooking oil, olive oil or castor oil, whale oil or EP oil. It is rather like asking 'I need to drill holes in rock – will metal be Ok for this?'

As someone said here recently, we all need to be careful about the various meanings of the words we use.

Cheers, Tim

WD40 is useless for storage, as it's name implies, it's used for water displacement. When it dries out it just leaves a sticky residue.

This is the sort of oil that does work well, I use it in my model engines for a long term layup Air Tool Oil

Hi Lee, I said most Disinfectants don't work on Coranavirus, which is true. Disinfectants target Bacteria and maybe Fungi. Virus are very different; maybe not even alive in the sense animals, bacteria and fungi are. Many substances effective against bacteria have no effect on viruses. Although some disinfectants are anti-viral a particular disinfectant's effectiveness depends on what it's made of, read the small print. I'd be surprised if a Supermarket or informed employer was using the wrong one. We might!

English abounds in words with subtly different technical, lay and trade meanings. I mentioned Antibiotics, Disinfectants, Antiseptics & Germicides and Lee adds Cleaners and Sanitisers. Sanitizer is American, and originally just meant disinfectant. Today a Sanitiser is more likely a combined cleaner and disinfectant, but they're not special. A particular Sanitisers effectiveness against COVID depends on its active ingredients. Necessary to use the right one.

Killing is an exact science. Most organisms dislike strong heat or extreme cold. Most are vulnerable to skin damage caused by strong chemicals. Many can be dehydrated with high-proof alcohol. Others can be poisoned with antibiotics or chemical agents. To deal with a threat some weakness is identified and exploited. It's a matter of selecting the best weapon for the job.

Cleaning alone isn't a particularly good way of dealing with a virus. While washing most of it safely down a drain is useful, the remainder stays active. And cleaning makes some of it airborne. Therefore best to combine cleaning with a potent anti-viral, so the beast is washed away and killed.

Bleach and Hydrogen Peroxide are oxidising agents effective against bacteria, fungi and viruses. Powerful chemicals capable of damaging surfaces and people. Good for Toilets rather than Kitchens. And these chemicals aren't good cleaners on their own. But bleach is a very good way of killing a virus, and it doesn't matter if detritus is left behind because a virus can only reproduce inside a host – there is no 'breeding ground' as would help a bacteria.

Lee's advice is good – wash hands regularly and don't touch face. Happens that Covid-19 is damaged by soap so it's quite simple to reduce the risk simply by washing hands.

The real danger is other people! In Sainsbury's yesterday I saw 4 old friends completely forget COVID precautions in the excitement of meeting for the first time in months. The women kissed and the men shook hands before standing in a tight ring to enjoy a long chat. On the way out they were still gas-bagging and I noticed one of the men had taken his mask off…

I would only Covid-clean tools in a workshop shared with someone else. You can't catch Covid-19 off yourself!

Having read Lee's & SOD's posts mentioning disinfectants i was somewhat concerned. I have been using a couple of 2 litre pressure spray bottles. One in the house for parcel deliveries & certain items of shopping ie items that other shoppers seem to love handling then put backon the shelf for no reason. I even spray the loaves of cut bread from our village shop, because the older villagers love to cough over them & fondle them. (I think they miss their deceased partners)

The other I carry in my van for spraying tools etc that may get shared with others when doing jobs at our sailing club (socially distanced of course). I also spray my hands from time to time if using handrails etc when touching others boats etc. & water is not immediately available

The product I use was purchased from a major builders merchant & is labelled as being to BS 6471. After reading the posts I researched a little & this BS does not seem to appear on any covid related info. So today I rang the manufacturers tech department. i was told that a major constituent is Quarterny Ammonium Compounds of which Benzl C12-16 alkylidnclyl chloride is one ( sorry if I have spelt that wrong ) These are used in the products specified as anti Virus specific products. The tech chap told me that because this disinfectant had not been specifically tested under the particular standards they could not make any claims.( they do have some that has been tested) However, as the chemicals used were the relevant ones he could confirm that this disinfectant was Ok in my domestic situation. He went on to say he was using it at home himself as it was much cheaper. He further felt that possibly not all disinfectants were advisable for use, but would not comment directly on other companies products.

The disinfectant cost £10-00 for 5 litres & has a dilution rate of 1:60

If any one wants to PM me I will tell them what builders merchant & what disinfectant – if that does not break the rules

That would be the same ‘blowlamp’ who was previously full of missionary zeal for BitCoin:
