Cleaning Draft Shield Panes
Select dissolvent depending on a dirt. Never soak the glass panes in alkaline solutions since they
interact with glass and may cause damage. Do not use cleansers containing abrasive substances.
For organic dirt use acetone first, next use water or detergent. For other than organic dirt use diluted
acid solutions (soluble salts of hydrochloric or nitric acid) or base solutions (ammonium or sodium
base).
To remove ACIDS use protophilic solvent (sodium carbonate), to remove BASE use protogenic
solvent (mineral acid of various concentration).
In case of heavy contamination use brush and detergent, nevertheless avoid detergents containing
large and hard molecules which could potentially scratch glass panes.
At the end of the cleaning process rinse the pane using distilled water.
Use soft brush with wooden or plastic handle exclusively in order to avoid risk of scratches. Do not
use wire brush.
Rinsing is a necessary cleaning process stage allowing to remove remaining soap, detergents and
other cleansers from the panes prior their reinstallation.
After preliminary cleaning process stage, rinse the pane using running water first, distilled next.
Avoid drying the panes either using paper towel or forced air circulation since some fibres, grains or
contamination of other type could permeate into the panes thus causing weighing errors.
We do not recommend using driers when drying measuring glass tools.
It is a frequent treatment to leave glass components on a rack to dry.
Cleaning Powder-Coated Components
For preliminary cleaning process stage you need running water or wet sponge featuring large holes,
this will help you to remove loose, heavy dirt.
Do not use cleansers containing abrasive substances.
Next, using cloth and cleanser-water solution (soap, dishwashing liquid) gently rub the cleaned
surface.
Avoid using cleanser without water since it may result with damage of the cleaned surface, please
mind that large amount of water mixed with cleanser is a must.
Cleaning Aluminium Components
While cleaning aluminium components use products acid by nature, e.g. spirit vinegar, lemon. Do not
use cleansers containing abrasive substances. Avoid using hard brush, this may cause scratches. It
is recommended to use microfibre cloth.
While polishing the surface use circular movements. Use clean, dry cloth to make the surface shine.
