Quats, such as the blue Lysol liquid, have two primary weaknesses. They have no
residual
killing power and they are not tuberculocidal. There are some relative new
products that
are still called quats, but are tuberculocidal.
Phenolics, such as the brown Lysol liquid, are highly corrosive and toxic to
humans. It is
tuberculocidal and does have bacteriostatic properties. Of course, that residue
is what
corrodes surfaces--or skin.
Hospital grade quats or phenolics do have a low in-use cost, because they are so
concentrated, but they still cost about $25.00 per gallon. Common dilutions are
1:128 or
1:256. Since I already have plenty of water, I buy the most concentrated
products, because
it saves on shipping.
Experience is something you do not get--until just after you need it.
