Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Several "do-it-yourself" home formulations were evaluated for performance on several substrates and typical soils for all purpose cleaning. All Purpose Cleaner Formulations:
Home Formulation 1 - Dissolve 4 tbls baking soda in 1 qt warm water for a general cleaner
Home Formulation 2 - Vinegar and salt, mix together into a paste for a good surface cleaner (another version is mix salt and water together with a little vinegar)
Home Formulation 3 - Liquid castile soap (small amount) and baking soda/borax with lots of water for floors walls or counters
Home Formulation 4 - Liquid castile soap (medium amount) and baking soda/borax for tubs, sinks, cat boxes or anything that can be well rinsed.
Home Formulation 5 - Baking soda and water, make a paste for all purpose cleaner
Home Formulation 6 - 3 tbsp vinegar, ½ tsp washing soda, ½ tsp vegetable based liquid soap (Murphy’s), 2 cups hot 2cups hot water and put in spray bottle or bucket. Apply and wipe clean. General cleaner

Many of the mixtures left behind a lot of residue when using the standard laboratory procedures for commercial cleaning products. Modification of the cleaning process may improve the effectiveness of these "do-it-yourself" formulations.
Home formulation 1 and 9 showed some signs of effectiveness, removing over 60% of the all-purpose soil.
