## Abstract

This invention relates to a multipurpose cleaner composition which has been found to be useful in a very broad range of cleaning applications when employed in various aqueous dilutions. The cleaning compositions of this invention have found utility in cleaning applications of low demand, such as cleaning of windows, to those of high demand, such as encrusted stoves or automotive engines and the like. Because the concentrated multipurpose cleaner is readily diluted, it can be marketed in a concentrated form and diluted by the user to the desired concentration for the particular cleaning job requirements, thus reducing the amount of cleaner packaging consumed by a household.

## Claims

### Claim 1

A multipurpose cleaning composition comprising:
from about 5% to about 20% by weight of sodium sulfite;
from about 0.5% to about 1.5% by weight of sodium meta bisulfite;
from about 0.5% to about 1.5% by weight of mono-normal-butoxy propanol;
from about 0.5% to about 1.5% by weight of mono-tertiary-butoxy propanol;
from about 0.5% to about 1.5% by weight of sodium xylene sulfonate;
from about 0.5% to about 1.5% by weight of the tetrasodium salt of ethylene-diamine tetraacetic acid;
from about 2% to about 5% by weight of the monosodium salt of isodecyloxypropyliminodipropionic acid;
said components in admixture with water and present in said composition in amounts sufficient to provide an essentially neutral composition with broad cleaning capabilities for a broad range of surface applications.
