A cleaning composition including a metal bisulfate and metal inorganic
salt acid package, and at least one surfactant. The cleaning composition
can be a one-step wheel cleaner/brightener. The composition preferably
contains no HF, no bifluoride, no oxalic acid, or other poisonous and
highly toxic materials commonly found in both industrial and consumer
wheel cleaners. Further, the wheel cleaner/brightener composition matches
or exceeds the performance of those hazardous formulations and does not
damage aluminum wheels even when applied to hot metal. The composition
can be a foam composition, provided in a foam dispenser. The foam
dispenser includes a container and a mechanical foaming head. The
container includes a cleaning composition containing a metal bisulfate
and metal sulfate acid package, and at least one surfactant, water, and a
foam-boosting solvent.
