Proper Disinfectant Application
What are the right ways to apply BotaniClean Disinfectant or Mediclean Germicidal Cleaner Concentrate (MGCC)?

The answer is easy - what's listed on the label!

BotaniClean and MGCC labels instruct users to apply the product to a pre-cleaned area until the surface is wet, then allow the surface to remain wet for the label-specified dwell time.

Fogging does not achieve these conditions, as it does not wet the surfaces sufficiently and will dry too quickly. Instead, use trigger sprayers or electric sprayers set to a coarse spray.

Both BotaniClean and MGCC have demonstrated effectiveness against viruses similar to SARS-CoV-2 (as the surrogate for COVID-19) under the current EPA Emerging Pathogens Standard, so they are included on List N: Disinfectants for Use Against SARS-CoV-2 (under their EPA registration numbers).  To ensure compliance with kill claims, use the disinfectant as instructed on the product label.
