Abstract

Cleaning solutions and related methods for cleaning and removing stains and residues from items and surfaces such as laboratory equipment and surfaces uses cleaning solutions containing from about 25 wt % to about 99 wt % of a liquid sulfoxide and from about 1 wt % to about 75 wt % of a base-water solution. A variety of bases can be used in the base-water solution so long as the base-water solution has a pH of at least about 8. The cleaning solutions are particularly fast and effective in cleaning stains caused by biological staining reagents and solutions. A preferred embodiment of the cleaning solution contains between about 80 wt % liquid sulfoxide, such as dimethyl sulfoxide (DMSO), and between about 10 wt % and about 20 wt % base-water solution, such as a 4.5% potassium hydroxide-water solution.
