Sonitron SK50 is a carpet prespray built around a non-solvent emulsifier for the removal of oil and grease. Sonitron says it is especially useful on greasy polypropylene carpets, and that it applies to all synthetic carpets, including 5th generation protected nylon.
The safety data sheet lists its uses as carpet shampoo, pre-spray and spot cleaner.
What It Is For
- Prespraying greasy and oily traffic lanes before extraction
- Polypropylene carpet, which holds oily soil
- Synthetic carpets generally, including 5th generation protected nylon (Sonitron)
Why a Non-Solvent Emulsifier?
Oily soil does not rinse out with water alone. A prespray has to break the oil into fine droplets that stay suspended in the solution so the extraction rinse can carry them away. SK50 does this with an emulsifier, not a solvent. The safety data sheet does not classify it as flammable and it is not dangerous goods for transport.
Directions for Use
Sonitron does not publish dilution rates for SK50 on its website. Follow the directions on the container label, and ask us for them if you need them before you order. As with any prespray, apply evenly, agitate, allow dwell time without letting it dry, then extract.
The concentrate is pH 10 and Sonitron names synthetic carpets only. Pre-test before using it on wool or other natural fibres.
Safety
Sonitron's safety data sheet (SDS 5052, revision 5, 3 February 2026) carries the signal word Warning: causes serious eye irritation, and harmful to aquatic life. Wear tight-fitting chemical splash goggles or a face shield and protective gloves when handling the concentrate. If it gets in the eyes, rinse cautiously with water for several minutes. Read the full SDS before use.
