Only works on the side visible to the UV rays, implements need to be turned over after 20 mins to sterilise the undersides. 

Often referred to as disinfectors as they are incapable of complete sterilisation. 

Maintains sanitation rather than sterilisation. ]]> 2022-09-30 13:33:45 UTC https://padlet.com/pamckenzie2/nfkw47jwslt8vsft/wish/2321061133 https://padlet.com/pamckenzie2/nfkw47jwslt8vsft/wish/2321062022 alcohol - surgical spirits, used on tools to remove grease and debris
barbicide - used to keep tools sterile, shelf life is around 2 weeks
