One step disinfectant (sporicidal) cleaner (disinfectant (sporicidal) with surfactant) is “preferred” (as I said in the previous post) according to experts of cleaning and disinfection and microbiology.
“At least” it is definitely more effective than the same disinfectant without surfactant and will ensure no barrier between microorganisms and the effect of antimicrobial agent.
Even when we always stick to the “2 step” cleaning and disinfection process , still disinfectant (sporicidal) with surfactant (one step disinfectant (sporicidal) cleaner) is advantageous
(Note that in my previous step I did not talk about the possibility of replacing 2 step process by 1 step process , I only said that disinfectants containing surfactants are “preferred” to disinfectants not containing surfactants and I said that room surfaces need detergent e.g. soap for cleaning)
