In the case when contamination is hard to remove, e.g. adhesive, rubber, resin, polyurethane foam
residues etc., you can use a special cleaning agents based on a mixture of aliphatic hydrocarbons
that do not dissolve plastics. Before using the cleanser for all surfaces we recommend carrying out
tests. Do not use products containing abrasive substances.
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 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 protofilic solvent (sodium carbonate), to remove BASE use protogenic solvent
(mineral acid of various concentration).
In case of heavy contamination use brush or detergent nevertheless avoid detergents containing
large and hard molecules which could potentially scratch glass panes.
Use soft brush with wooden or plastic handle exclusively to avaoid risk of scratches. Do not use wire
brush.
At the end of the cleaning process rinse the pane using running water first, distilled next.
Rinsing is a necessary cleaning process stage allowing to remove remaining soap, detergents and
other cleansers from the panes prior their reinstallation.
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.
One shall not use driers when drying measuring glass tools.
It is a frequent treatment to leave glass components on a rack to dry.
Cleaning stainless steel components:
Avoid using cleansers containing any corrosive chemicals, e.g. bleach (containing chlorine). Do not
use abrasive substances. Always remove the dirt using microfiber cloth to avoid damage of protective
coating.
In case of a daily maintenance:
1. Remove the dirt using cloth dipped in warm water.
2. For best results, add a little dishwashing detergent.
Cleaning powder-coated components:
For preliminary cleaning 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.
