Can I clean and sanitise at the same time? April 29, 2020

Presco Environmental technician, Jeremy, using dry ice blasting to clean and sanitise at the same time.

Yes, you can clean and sanitise at the same time. 

Food safety 101 states you must clean first, sanitise second.  There is one way around this; dry ice blasting.

Dry ice blasting sanitises as it cleans. 

You may have read about this before, in a 10-part series I wrote on the benefits of dry ice blasting.  With people frantically looking for information on sanitising since COVID-19 took the world by storm, I thought it a good idea to refresh this information. 

So, how does it work?

Dry ice is super cold: -79˚C.  This causes dry ice blasting to instantly kill and remove bacteria (such as Salmonella, E-Coli, Listeria) from the surface of an object, disinfecting, sanitising and decontaminating all in one pass. Also, the cleaning process is totally dry.  This means you are not introducing moisture which could promote bacteria growth. 

And why does this matter?

  1. It saves you money. Cleaning and sanitising in one pass can cut your cleaning time in half.  This drastically reduces factory downtime, and you can get right back to production.  You also won’t need to pay for sanitiser (or any chemical at all). 
  2. No chemical is used. If your product cannot come into contact with chemical, sanitising can be an issue.  With dry ice blasting, no cleaner or sanitiser needs to be used; it is a chemical-free process.  You can learn more about this here

Dry ice blasting is an amazing cleaning method, that solves the most difficult problems.  Cleaning and sanitising at the same time is merely one of many benefits.  To find out if this method will help you, visit our service page here.  

Keep in mind, if you aren’t using dry ice blasting, the original rule still applies: clean first, sanitise second.  Matthew wrote an article called ‘You Can’t Sanitise Dirt: 7 steps to clean.‘  If you want to learn more about the steps you need to take to sanitise a surface, this would be a good place to start.
