About Alcohols

Examples: ethanol, industrial denatured alcohol (IDA), such as industrial methylated spirit (IMS), Isopropanol (also known as 2-propanol, isopropyl alcohol, IPA or surgical spirit)

  • Alcohols need to be least 70% (70 parts alcohol, 30 parts purified water) to be effective. Both components play a crucial role in deactivating the virus by breaking down the lipid shell. Consult the manufacturer’s instructions to make sure the ethyl alcohol component is not diluted below 70%.
  • Industrial alcohols can be difficult to buy and transport. You will need to register with HMRC.
  • Methylated spirits bought from DIY stores are not generally suitable for treating historic surfaces because they usually include harmful additives and dyes that could stain historic surfaces.
  • Isopropanol is readily available at 70% and can also be purchased as impregnated wipes. Always read the product labelling or MSDS to check that isopropanol and deionised water are the only ingredients.
