Dissolves alginate and plaster residues from containers, mixing spatulas and impression trays. Add two scoops (50 grams) of Cavex GreenClean to half a litre of warm water. Remove any loose alginate residues. Allow the Cavex GreenClean solution to dissolve alginate and/or plasters from the surface for 15 to 30 minutes, then rinse or brush off. ItÕs done! No more scraping or scouring. Cavex GreenClean is pH-neutral and biodegradable making it safe to use and environmentally friendly allowing residues to be removed in the sink without problems. Only works on the alginate or plaster residues and will not affect other surfaces it contacts. Gentle on the skin.
