The weakest commonly used disinfectant is generally considered to be methyl alcohol (methanol), which has a very weak bactericidal action compared to other alcohols like ethanol or isopropanol.
Low-level disinfection kills some viruses, bacteria, and fungi but not mycobacteria or spores. Intermediate and low-level disinfectants (except chlorine bleach) must have a Drug Identification Number (DIN) or Natural Product Number (NPN) on the label.
Low level disinfection: Kills some viruses, bacteria, and fungi. Intermediate level disinfection: Kills a larger range of pathogens than low-level disinfection, but does not kill bacterial spores.
Hydrogen peroxide is active against a wide range of microorganisms, including bacteria, yeasts, fungi, viruses, and spores 78, 654.
Different groups of bacteria vary in their susceptibility to biocides, with bacterial spores being the most resistant, followed by mycobacteria, then Gram-negative organisms, with cocci generally being the most sensitive.
Choose hydrogen peroxide.
That breaks down into oxygen and water. It's kinder to the environment (and many surfaces, fabrics and your hands) than chlorine bleach. That's why it's touted as the environmentally safest alternative to chlorine-based bleaches.
Antimicrobial resistance mechanisms fall into four main categories: (1) limiting uptake of a drug; (2) modifying a drug target; (3) inactivating a drug; (4) active drug efflux.
Like most disinfectants, it kills pathogens by penetrating their cell walls. But compared with bleach, hypochlorous acid has been shown to be more than 100 times more effective at much lower concentrations, and it works much faster.
Both Clorox and Lysol wipes are EPA-approved to kill 99.9% of viruses and bacteria, including nasty ones like E. coli, Salmonella, and Influenza A. I tested both on kitchen counters, door handles, and my phone screen (gross, I know). They both did a solid job.
To make your own disinfecting spray that can be safely used on a variety of surfaces around your home, just combine the following ingredients in a large glass spray bottle: 1 cup water, 1 cup white vinegar, 2 tablespoons rubbing alcohol, 20 drops lemon essential oil, 20 drops tea tree essential oil.
Low level disinfectant means a disinfectant that rapidly kills most vegetative bacteria as well as medium-sized lipid containing viruses, when used according to labelling. It cannot be relied upon to destroy, within a practical period, bacterial endospores, mycobacteria, fungi, or all small nonlipid viruses.
Cleaning can be thought of as the lowest intensity of the three levels of contamination, but that doesn't make it less important. Cleaning involves the act of removing organic material such as dirt and other impurities including blood, feces, etc.
Bleach is a strong and effective disinfectant – its active ingredient sodium hypochlorite is effective in killing bacteria, fungi and viruses, including influenza virus – but it is easily inactivated by organic material. Diluted household bleach disinfects within 10–60 minutes contact time (see Table G.
Low-level disinfectants are used to disinfect noncritical items that come into contact with skin. This includes shared patient-care devices that staff would use on multiple patients through the course of any given work day, including hard surfaces like bed rails and equipment like blood pressure cuffs.
Utilities add disinfectants, such as chlorine or chloramine, to tap water to kill germs and make it safe to drink. Low levels of disinfectants kill germs as water travels through pipes to your tap. The low levels of disinfectants allowed in tap water do not make people sick.

Hydrogen peroxide is one of the most powerful natural cleaning and disinfecting agents. Health professionals trust it against harmful bacteria, antigens, and viruses.
Strains of pathogens that've developed resistance to multiple drugs are the hardest to get rid of. Infections like MRSA and CREs are often resistant to more than one type of antibiotic, so finding one that's effective (or a combination of medications that work together) can be challenging and take a long time.
Bacteria resistant to antibiotics
Antimicrobials – including antibiotics, antivirals, antifungals, and antiparasitics – are medicines used to prevent and treat infectious diseases in humans, animals and plants. Antimicrobial Resistance (AMR) occurs when bacteria, viruses, fungi and parasites no longer respond to antimicrobial medicines.
