ABSTRACT:
A cleaning kit for use in cleaning surfaces in clean rooms, semiconductor fabrication plants, pharmaceutical manufacturing facilities, etc. A stack of extremely clean wipers is packaged together with a container of cleaning fluid in a liquid-tight outer container. The kit is stored until just before it is to be used. Fluid is released from the inner container into the wipers. In one embodiment, the inner container is frangible and is broken by application of hand pressure to the outside of the outer container. The cleaning liquid is allowed to soak into the wipers, and the wipers are removed from the outer container for use. The container can be resealed to protect the wipers after the package has been opened. This device and method minimize deterioration of the wiper material due to prolonged contact with the cleaning fluid, and minimize the loss of effectiveness of substances such as biocides which might deteriorate due to prolonged contact with the wiper material.
