Penetrant & Dirt Remover (SC 21) is a versatile cleaning solution from MR Chemie, developed for the effective removal of penetrant residue (red and fluorescent) and industrial dirt from various surfaces. It is ideal for use in NDT environments where surfaces must be free of dirt and indicator devices prior to testing.

Key features and benefits

• Effective against both red and fluorescent penetrant residues and general industrial dirt.

• Can be used undiluted or diluted up to 1:10 with water, depending on how heavy the soiling is.

• Low pH value (~ 6) makes the product relatively gentle on surfaces.

• Suitable for industrial floors, workbenches and non-corrosive metals — test on difficult and untreated surfaces first.

Technical specifications

• Delivery form: Bulk packaging, 1 litre.

• Storage temperature: +5 °C to +45 °C. Application range approx. +5 °C to +50 °C.

• Shelf life: At least 3 years when stored correctly.

• Directions for use: Apply directly or dilute 1:10 with water; leave on for 5–10 minutes on stubborn dirt; use a melamine sponge for smooth surfaces or a pot sponge for rough floors.

Areas of application

• Cleaning surfaces and components before penetrant inspection (FPI) to ensure that residues do not affect the test result.

• Removal of penetrant stains and general industrial dirt on floors, benches and metal surfaces.

• Cleaning in inspection tools and environments where high cleanliness is required for NDT procedures.

• Maintenance and pre-inspection preparations, to reduce false indications during testing.
