1. A system for sanitizing or disinfecting, the system comprising:
A) a resealable package containing a plurality of initially dry wipes; and
B) a sanitizing or disinfecting composition contained within a burstable pouch, which is contained within the package but separate from the dry wipes, wherein the burstable pouch is configured to dose the plurality of initially dry wipes with the sanitizing or disinfecting composition upon bursting of the pouch containing the sanitizing or disinfecting composition, wherein the sanitizing or disinfecting composition comprises:
(a) from about 0.05% to less than 0.5% by weight of free available chlorine as provided by a hypochlorite; and
(b) at least one of:
i) a nonionic surfactant comprising at least one of an alcohol ethoxylate, an alcohol propoxylate, or an alkyl polyglucoside; or
ii) a zwitterionic surfactant comprising at least one of lauramine oxide, decylamine oxide, or myristyl dimethylamine oxide,
wherein:
1) the composition has an R value that is greater than 0, where R is defined as the sum of the concentration of any nonionic or zwitterionic surfactants plus any cationic surfactants, divided by total surfactant concentration, wherein total surfactant concentration includes any surfactant aids;
2) the composition is free of anionic surfactants other than surfactant aids;
3) the composition has a pH from 8.5 to 12.5;
4) the sanitizing or disinfecting composition exhibits at least a 3-log reduction in a C. diff population within 10 minutes;
5) the sanitizing or disinfecting composition exhibits no more than a 500 ppm reduction in hypochlorite concentration over a 1 year period, and/or no more than a 0.5 pH drop over 1 year when the composition is sealed within the pouch.
