Abstract
Abstract A cleaning composition is provided which includes a lower alcohol, ultrapure water, a surfactant, 3,5-dimethyl-1-hexyn-3-ol and ammonia solution. This cleaning solution is 100 percent volatile, water-clear, and contains no solids or colloidal matter, in addition to being contaminant- and particulate-free, it is found to leave no detectable residue even if not fully wiped off in a cleaning operation.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
35 words
A method of cleaning lenses and mirrors of electrophotographic copiers comprising providing a filmed lens or mirror surface, applying a cleaning solution which consists essentially of lower alcohol, ultrapure water, ammonia solution and 3,5-dimethyl-1-hexyn-3-ol surfactant.
Claim 2
Independent Claim
35 words
A method of cleaning lenses and mirrors of electrophotographic copiers comprising providing a filmed lens or mirror surface, applying a cleaning solution which consists essentially of lower alcohol, ultrapure water, ammonia solution and 3,5-dimethyl-1-hexyn-3-ol surfactant.
Claim 3
Dependent Claim
24 words
The method as defined in claim 1 wherein said lower alcohol is a mixture of 100 parts by volume ethanol and 5 parts methanol.
Claim 4
Dependent Claim
22 words
The method as defined in claim 1 wherein said water has the quality of greater than 10 megohm-cm resistivity and is ultrafiltered.
Claim 5
Dependent Claim
23 words
The method as defined in claim 1 wherein said alcohol is selected from the group consisting of ethanol, methanol, propyl and mixtures thereof.
Claim 6
Dependent Claim
21 words
The method as defined in claim 1 wherein said alcohol is present in 70-95 parts for 100 parts of total solution.
Claim 7
Dependent Claim
