ALCOHOL BASED SANITISER SURFACES SPRAY

Jo Mantini

 

With the Covid-19 emergency, many of us are thinking about how we can keep our homes as clean and germ-free as possible. Even if lots of the shops are selling out so many products, especially in the cleaning section, you still have plenty of options.

 

In regular times you would want to clean and sanitise every few days, but these are anything but normal times. 

Based on what is currently known, Coronavirus spreads from person-to-person among close contacts (within about 6 feet) via respiratory droplets. On the other hand, the transmission to persons from surfaces contaminated with the virus has not been documented. Current evidence suggests that Coronavirus may remain viable for hours to days on surfaces made from a variety of materials. Cleaning dirty surfaces, followed by disinfection, is the best practice to prevent viral respiratory illnesses in households and community settings.

So, not just sanitising, but cleaning first is a good rule, especially if very high risk and vulnerable people are living with you.

  • Cleaning is about removing contaminants from a surface.
  • Disinfecting is about killing pathogens.

It's better to first clean the area with a soapy sponge or cloth and then apply any disinfectant. In terms of what to clean, anything that you are putting your hands on should be cleaned. 

A good rule is to thoroughly wash your hands when you get home before you touch anything. This is when you are likely to spread unwanted germs.

 

Bleach could be excessive in most cases, if you don't have to sanitise a place open to the public, but just your private home. In fact, we need to remember that cleaning agents and beauty products could be dangerous for our respiratory system. There is a study that shows that while transport-derived emissions of volatile organic compounds (VOCs) have decreased owing to stricter controls on air pollution, volatile chemical products derived from coatings, printing inks, adhesives, cleaning agents, and personal care products has increased and now contribute fully at one-half of emitted VOCs in 33 industrialised cities (full study here). 

Also, you should never mix bleach solution with ammonia or any other cleanser. Use bleach as a last resort if you can't source any other kind of disinfectant. 

You can make your own bleach-free sanitiser spray using Peroxide (recipe here).

The WHO (World Health Organisation) suggest using for disinfection alcohol solutions with at least 70% ethyl alcohol, or sodium hypochlorite at 0.5%.

 

 

Making your own alcohol-based sanitiser for cleaning your home surfaces is very easy as you need just two ingredients!

 

INGREDIENTS

 
Ethyl Alcohol  
Boiled Water 

 

The quantity depends on the alcohol content you decide to use, and it's very easy to calculate. In fact, there are different types of alcohol.

 If you are using a 99.9% alcohol, and your solution should be at 70% alcohol concentration, then calculate using the following:

1000 ml (total solution) X 70 (% concentration) / 99.9 (% alcohol content)

In this case, you need 700 ml of alcohol and 300 ml of water. 

 

If you are using a 90% alcohol, the calculation is really simple to modify the ingredients' quantity. 

1000 X 70 / 90 = 778 alcohol + 222 water

Have a look at this file for more info. 

The best alcohol to use is the Grain Neutral Spirit, because is "natural" alcohol without any additives.

You can use rubbing isopropyl alcohol as an alternative, but this alcohol has additives and is synthetic. It can cause damage to the central nervous system and drowsiness or dizziness when inhaled (have a look at the file)

 

HOW TO USE 

 

Spraying and leaving the disinfectant untouched on surfaces for around 30 seconds before wiping helps to kill the bacterias more efficiently. Make sure that the area is well-ventilated while you’re cleaning. 

 Boiled water is an essential precaution to avoid every risk of microbiological contamination (eg. spores). 

 It also very important to wash your cloths and sponges, so they cannot spread germs themselves. Pop the sponges into the dishwasher or washing machine, or soak them with hot soapy water and sodium percarbonate (more info here) and leave overnight. 

It's also a good idea to run the washing machine empty once a month at a high temperature with 50 g of sodium percarbonate to sanitise and prevent the growth of germs (more tips here)

 

Always keep calm, stay safe

and don't forget to wash your hands! ;)

 

HAPPY DIY
