The invention concerns a three component system comprising surface-active substances, vitamins and metal ions for efficient destruction and removal of contaminating proteins, nucleic acids and microorganisms from surfaces like for example laboratory benches, floors, equipment and instruments. These non-corrosive and non-toxic solutions for removal of proteins, nucleic acids and microorganisms are applied by spraying, rubbing or immersion of contaminated surfaces thereby destroying, solubilizing inactivating and removing proteins and nucleic acids. In that way also microorganisms are killed with high efficiency and at the same time all genetic information is inactivated.

The invention relates to a method for producing electrolyte solutions consisting of trialkylaluminium AlR, MAlR, MAlRand an aromatic hydrocarbon. According to the invention, a mixture of MOR and MOR is reacted with trialkylaluminium AlRat temperatures below 25&#xb0; C. in an aromatic hydrocarbon. MAlR/MAlRis isolated from the obtained mixture and a ready-for-use electrolyte for the electrochemical deposition of aluminum-magnesium alloys is obtained by the addition of aromatic hydrocarbon.

Disclosed is a process for preparing methyltransition metal compounds in which the halide metallocene precursor to be alkylated is initially charged in a hydrocarbon desired for the subsequent application, admixed with an aluminum alkyl and subsequently converted by addition of an inorganic salt into the end product: ##STR1## The reaction solution thus obtained can be freed of precipitated salts by simple filtration and directly used for polymerization, since the dialkylmetallocene is obtained in high purity and yield. If desired, it can also be isolated without problems.
