Important Information

Always work on cool surfaces and perform a spot test before first use. Surfex-HD is suitable for a wide variety of automotive and household cleaning tasks when diluted correctly, but stronger dilutions should only be used where appropriate for the surface being cleaned.

PRO TIP: Keep multiple spray bottles labelled with your favourite Surfex-HD dilutions. A 2% mix is ideal for interior plastics, 5–10% is excellent for tyres and wheel arches, while stronger mixes can tackle engine bays and heavy grease, all from one incredibly versatile product.
