Alkaline Deruster HD is a highly concentrated, alkaline, aqueous cleaner with chelants and flash rust inhibitors to remove rust, carbon, scale, and other soils. Designed for global regulatory acceptance.
Alkaline Deruster HD is designed for immersion applications that use turbulation or ultrasonic agitation and is low foaming for use in spray wash applications where ventilation is adequate. Readily soluble in tap water, Alkaline Deruster HD is free rinsing. It provides unparalleled cleaning performance while providing a water-break-free or higher level surface cleanliness.
Always follow directions and information directly on the product label before use. Download Safety Data Sheet for more information.
[1] Do not add Alkaline Deruster HD to hot water on initial charge (it is not necessary that make-up be cold).
[2] If ultrasonic agitation is present, it may be possible to operate with concentrations as low as 0.2% (v/v) on some soils. Parts should be precleaned to remove gross filth such as oils and greases to minimize contamination of Alkaline Deruster HD.
[3] This product is inherently non-foaming at all temperatures but excessive foaming may occur if the soil is inherently foamy.
[4] For titanium descaling, do not exceed tank strength of 30% (v/v), operating temperature of 170°F (77°C) or 15 min cleaning duration to avoid etching and excessive stock lost. Titanium should also be cleaned only in a tank dedicated to that alloy as the presence of other metals increases the potential for etching.
[5] Some aluminum alloys may be safely cleaned at dilutions of less than 0.5% (v/v) with exposures of less than 60 seconds and temperatures below 120°F (49°C). Test on a representative scrap part first.
Alkaline Deruster HD is suitable for a variety of alloys. Some selected categories of materials compatible with Alkaline Deruster HD include:
Not for use on aluminum-based alloys and IVD coatings, chromium and tin plating, copper-based alloys (brass, bronze, 90/10 and 70/30 copper nickel alloys), and zinc galvanized steel substrates.
Material compatibility and soil removal should always be confirmed via testing with specific contaminants under specific cleaning conditions.
Alkaline Deruster HD removes a wide range of organic and inorganic soils. Some categories of soils that can be removed with Alkaline Deruster HD include:
Material compatibility and soil removal should always be confirmed via testing with specific contaminants under specific cleaning conditions.
