The term "sos pad" has become synonymous with the rough, abrasive pad used for cleaning tough stains and grime. However, there are several alternative synonyms when referring to this type of cleaning tool. Some of the most common synonyms include scouring pad, scrubbing pad, abrasive pad, steel wool pad, and heavy-duty cleaning pad. Each of these words accurately describes the texture and purpose of the pad and can be used interchangeably with "sos pad". It's important to note that while these pads are effective cleaning tools, they should be used with care on delicate surfaces to avoid causing damage.
