A change in color from green to brown in your homemade dishwashing liquid could indicate several potential issues:
Ingredient interaction: Different ingredients used in your homemade dishwashing liquid may have reacted with each other over time, leading to a change in color. Some ingredients, such as certain oils or botanical extracts, can oxidize or degrade, causing discoloration.
Contamination: If the dishwashing liquid was not properly stored in a clean and airtight container, it could have been exposed to contaminants. Bacteria or other microorganisms can multiply and cause discoloration or spoilage.
Shelf life: Homemade products typically have a shorter shelf life compared to commercially manufactured ones, as they may lack preservatives or stabilizers. Over time, the natural degradation process can occur, leading to changes in color, odor, or effectiveness.
To address the issue and potentially salvage your dishwashing liquid, here are some steps you can take:
Evaluate the smell and consistency: Besides the color change, check if there are any unusual odors or changes in the texture or consistency of the dishwashing liquid. If it smells off or has an unpleasant odor, it may be an indication of spoilage or bacterial growth, and it is best to discard it.
Strain and filter: If there are no signs of spoilage or contamination, you can try straining the dishwashing liquid through a fine mesh or cheesecloth to remove any particulate matter or impurities that may be causing the discoloration. Transfer the strained liquid into a clean and airtight container.
Test effectiveness: Before using the dishwashing liquid on your dishes, test it on a small area or a few items to ensure it still cleans effectively. If you notice any adverse effects, such as residue, poor cleaning performance, or skin irritation, it's best to discontinue using it.
Consider making smaller batches: To prevent issues like discoloration or spoilage, consider making smaller batches of homemade dishwashing liquid that can be used within a shorter time frame. This reduces the likelihood of degradation or contamination.
It's important to note that homemade products may not have the same stability or consistency as commercially produced ones, as they lack the formulation precision and testing done in a controlled manufacturing environment. If you continue experiencing issues or concerns, it might be worth considering using commercially manufactured dishwashing liquid instead.
