User Manual | Laboratory Fume Cupboard | Cleaning of Laboratory Fume Cupboards
If the contaminants are not removed immediately, standard domestic cleaners can be used, such as washing powder,
liquid or hard soap, which do not contain any abrasive components. If there is a more intense contamination, it is
advisable to leave the cleaner to soak in. Finally, all cleaning agent residues should be removed with water and kitchen
paper or a soft cloth.
7.2.2 Melamine-coated chipboard (DBS)
Standard domestic detergents or grease-dissolving all-purpose cleaners can be used for cleaning melamine-
coated chipboard. The use of so-called balsam detergents should be avoided, as the substances contained in
these leave a fi lm on the surface which is diffi cult to remove. The use of abrasive cleaners, aggressive cleaning
agents and descalers should also be dispensed with, as these damage the surface.
Cleaning the surface of melamine-coated chipboard.
The basic cleaning of the surface is carried out with a solution of warm water and detergent. The solution
should be applied to the contaminated area. In the case of heavier soiling, the solution can be left to soak briefl y.
Prolonged soaking must, however, be absolutely avoided. Subsequently, the cleaning agent residues should be
removed from the surface using warm water and kitchen paper or a soft cloth and the surface dried with a dry,
lint-free cloth in the direction of the pattern.
7.2.3 TRESPA
®
TOPLAB
®
PLUS
To clean TOPLAB®PLUS surfaces, a mild household cleaner or organic solvent can be used. Abrasive or
polishing cleaners damage the surface and must, therefore, not be used.
Cleaning the surface of TOPLAB
®
PLUS
The surface should be cleaned with a dry or damp cloth and, if necessary, a mild household cleaner. The surface
is then wiped with an absorbent cloth. Special stains, such as solvent-based lacquers should be removed with
an organic solvent, e.g. white spirit.
7.2.4 Compact board (coloured high-pressure-compressed laminate board HPL)
When cleaning the surface of the compact board, a soap solution or suitable organic solvent can be used.
Cleaning with abrasive cleaners or bleach, strong alkalis, strong acids or other salts damages the surface.
Cleaning the surface of compact board
Apply a soap solution to the contaminated area with a damp cloth and allow to act for a short time. Then
remove the soap residue using kitchen paper and water. In the case of more intensive contamination or staining,
an organic solvent such as benzine can be used.
