The Real Stuff

Another unpaid product endorsement. Commercial, professional grade cleaners and disinfectants work many times better than anything you can buy in the grocery store, but you have to be smart enough and responsible enough to use them properly. If you aren’t, then leave stuff like this to the professionals.


D128 is a professional dual-quaternary disinfectant. It is generally used to disinfect hard non-porous surfaces in kennels, livestock quarters, and operating rooms. Clean the room first to remove large organics - chunks of dirt and poop, etc. - and then spray the area down with this stuff, diluted 1 ounce per gallon. Spray enough so that the area stays wet for 10 minutes.

D128 kills damn near everything at that dilution, and will handle canine parvo at a 4 ounce per gallon dilution.

It is available from most veterinary supply companies, for about $20 per gallon plus 10lb worth of shipping and handling.

It is not generally available for non-professionals, ie it isn’t sold at Home Depot or in the grocery store. It’s serious stuff, and smart use requires gloves and goggles and perhaps a respirator if used in poorly ventilated areas.

Effective against the following pathogens:
Pseudomonas aeruginosa1, Staphylococcus aureus1, Salmonella enterica, Acinetobacter calcoaceticus, Bordetella bronchiseptica, Chlamydia psittaci, Community Associated Methicillin-Resistant Staphylococcus aureus – CA-MRSA (NRS384) (USA300), Community Associated Methicillin-Resistant Staphylococcus aureus – CA-MRSA (NRS123) (USA400), Enterobacter aerogenes, Enterobacter cloacae, Enterococcus faecalis-Vancomycin Resistant (VRE), Escherichia coli1,Fusobacterium necrophorum, Klebsiella pneumoniae1, Legionella pneumophila, Listeria monocytogenes, Pasteurella multocida, Proteus mirabilis, Proteus vulgaris, Salmonella enteritidis, Salmonella typhi, Salmonella typhimurium, Serratia marcescens, Shigella flexneri, Shigella sonnei, Staphylococcus aureus-Methicillin Resistant (MRSA), Staphylococcus aureus-Vancomycin Intermediate Resistant (VISA), Staphylococcus epidermidis2, Streptococcus faecalis1, Streptococcus pyogenes, *Adenovirus Type 4, *Adenovirus Type 7

– at 4 oz per gallon,
*Avian Influenza (H5N1), *Avian polyomavirus, *Canine distemper, *Feline leukemia, *Feline picornavirus, *Hepatitis B Virus (HBV), *Hepatitis C Virus (HCV), *Herpes Simplex Type 1, *Herpes Simplex Type 2, *Human coronavirus, *HIV-1 (AIDS virus), *Infectious bovine rhinotracheitis, *Infectious bronchitis

Effective against 99.9% of Influenza A that causes the flu.

Mold, mildew, fungus, and most viruses don’t stand a chance against dual quaternary disinfectants. D128 costs about a quarter of KCT Quat, which uses nearly the same ingredients but at different ratios. It is a violation of federal law to use either product in a manner inconsistent with it’s design.

But holy cow, does this stuff work. It will work fine in moderately hard water (400 ppm) and up to 5% organic/soil contamination. Best bet is to dilute it with distilled water, since you’re spending the money.

  2. Pretty sure you’d only mix it once. And it’s this sickly green color too.

    Alcohol - ethyl or methyl - is another kind of disinfectant. I have no idea how the dimethyl ethyls in D-128 would react, seeing as they themselves are alcohol-like ... isotopes? ... of the main chemical.

    Is there a chemist in the house? This is beyond my level. And yes, I know Rich was just being his daily wiseguy self, but he did hit on a common question (what happens when I mix this germ killer with that one? [though I think he was thinking more along the shaken not stirred lines than the more effective germicide ones]).
