Dry mixture of that aids in the removal of heat scales and carbon smut from ferrous, stainless steel and high temperature alloys without corrosion of the base metals. Treatment with Freiclean 105CT can improve the subsequent pickling and coating uniformity by removing any interfering heat scales or carbon smuts from the substrate.

Freiclean 105CT is a dry mixture of sodium hydroxide and potassium permanganate that aids in the removal of heat scales and carbon smut from ferrous, stainless steel and high temperature alloys without corrosion of the base metals. Treatment with Freiclean 105CT can improve the subsequent pickling and coating uniformity by removing any interfering heat scales or carbon smuts from the substrate.

Freiclean 105CT is a highly alkaline and oxidizing material. Contact with skin or eyes may cause irritation or burns. Observed the same safety precautions as when handling caustic type materials. (P.P.E.) Personnel Protective Equipment should include eye protection, rubber gloves and apron or other protective clothing when working with this material. Processing tanks using this material must have adequate exhaust system to protect workers against irritating or corrosive airborne contaminants.

When making up new solutions add Freiclean 105CT SLOWLY to cold water with constant stirring. Heat is generated as this material is dissolved into water, using warm or hot water to make-up the bath could cause boiling or eruption of the tank. If it is necessary to make replenishment additions to the hot tank, spread the Freiclean 105CT addition over the surface of the tank a little at a time while stirring.

This material can be used with 300 series stainless steel or mild steel tanks and heaters. However the most efficient method of heating is with gas burners placed beneath the tank. Racks and baskets are usually made from 300 series stainless steel.

Ventilation equipment should be made of materials that resist oxidizers and caustic fumes. Do not use ductwork made of aluminum, organic materials or with organic linings such as wood, plastic or paint.

• Pre-cleaning to remove organic oils and grease with a Freiclean alkaline cleaner.
• Water rinse to remove the acid.
• 15 to 30 minute soak in the Freiclean 105CT bath.
• Water rinse to remove the Freiclean 105CT solution.
• An acid pickle or bright dip to remove any staining and further loosen the smut and scale.
• Water rinse to remove the acid and loose soils. (Cleaning cycle can be repeated if not
totally clean.)
• Coating or sealing the cleaned metal surface.
