Sonitron SK25 is a general-purpose, water-miscible spotter for water-based stains on carpet and upholstery. It can be used by absorption and does not need to be extracted, which makes it a practical everyday spotter for jobs where no machine is on site.
Sonitron notes that general cleaners often carry SK25 together with Sonitron S110 for daily carpet maintenance: SK25 for water-soluble stains, S110 for solvent-soluble ones.
What It Is For
- Water-based spots and spills on carpet and upholstery
- Daily maintenance spotting in offices, hotels and other commercial sites
- Spotting by hand where the area cannot be extracted
It is not the product for grease, oil, tar, gum or ink. Use a solvent spotter such as S110 or GROG for those.
Directions for Use
Pre-test in an inconspicuous area. Apply to the stain, allow a short dwell, then blot with a clean absorbent cloth, working from the outside in. Repeat while the stain is still transferring. Follow the container label for any further directions.
Safety
Sonitron's safety data sheet (SDS 5050, revision 3, 3 February 2026) does not classify SK25 as hazardous, and no special protection is required in normal use. For large spills, wear eye protection and gloves. Read the full SDS before first use.
