What likely caused the poor cleaning results observed?

The likelihood that the detergent did not meet expectations is a valid cause for poor cleaning results. If the detergent is ineffective or not formulated for the type of soil or surface being cleaned, it won't be able to break down dirt, grease, or stains effectively. Detergents have specific compositions that target different types of cleaning tasks; if the product does not align with the cleaning requirements, then it will fail to deliver satisfactory results.

It is also important to consider that even with proper application and equipment, if the cleaning agent itself fails to perform as intended, the overall effectiveness of the cleaning process will be compromised. This highlights the critical role of selecting the right cleaning product tailored to the specific cleaning job at hand.
