The present invention generally relates to methods of cleaning residual pesticide from an agricultural vessel, and to kits and compositions useful for the practice of such methods.

A decontamination composition with at least one primary neutralizing agent and at least one secondary neutralizing agent, for the removal of chemical residues, to a method for employing the composition, and the use of the composition for removing residues on materials, machines, and equipment soiled with chemicals of any type, such as a corrosive product or a chemical containing fluoride ions.

A detergent composition is a detergent composition for removing temporary adhesive containing a silicone compound that is present on a substrate. The detergent composition contains: (A) an organic solvent: 75 to 99 parts by mass; (B) water: 0 to 5 parts by mass; and (C) an ammonium salt: 1 to 20 parts by mass (where (A)+(B)+(C)=100 parts by mass). The organic solvent does not contain an organic solvent having a hydroxy group and contains, in 100 parts by mass of the organic solvent, 50 parts by mass or more of an organic solvent having a heteroatom. The ammonium salt contains at least one kind of a hydroxide ion, a fluoride ion, and a chloride ion.

The present invention addresses the problem of providing a remover composition which can sufficiently remove ruthenium (Ru) remaining on substrates and can be inhibited from evolving RuO.sub.4 gas. The remover composition, which is for removing ruthenium remaining on substrates, has a pH at 25° C. of 8 or higher and includes one or more pH buffer ingredients.

A composition for dissolving abrasive particles, and a cleaning method using the composition are provided. The composition includes a sulfur-containing organic acid, a fluorine ion-containing compound, and a solvent, and a turbidity change rate (%) measured at 60° C. for 15 minutes may be in a range of −80 to −99.

Warewash detergent compositions with reducing agents to overcome corrosion challenges in stainless steel dish machines subject to conditions from chlorine sanitizing rinse steps (or other oxidizing chlorine containing compositions) are provided. Liquid and solid detergent composition beneficially containing a reducing agent that reacts with chlorine introduced in sanitizing rinse steps that follow detergent cleaning steps are provided. Methods for ware washing using the detergent compositions with reducing agents and methods for reducing residual chlorine in a ware washing cycle are also provided.

Provided therefore herein is a novel acidic fluoride activated cleaning chemistry. The present invention includes novel acidic fluoride activated, unique organic-solvent based microelectronic selective etchant/cleaner compositions with high metal nitride etch and broad excellent compatibility, including tungsten (W) and low-k. It does not use W-incompatible oxidizers, such as hydrogen peroxide or particle-generating corrosion inhibitors.

The present invention relates to a method for the corrosion-protective and cleaning pretreatment of metallic components, produced at least partially from metallic materials from the elements iron, zinc and/or aluminum, with the use of an acid aqueous composition containing, in addition to the water-soluble compounds of the elements Zr and/or Ti causing the conversion of the metal surface, a mixture of an aliphatic diol and an aliphatic saturated polyhydroxy compound. It also comprises a chrome(VI)-free aqueous composition based on the constituents mentioned above which delivers outstanding results in cleaning and simultaneous corrosion-protective conversion of technical metal surfaces in one method step.
