GLASS
CARE
How to properly clean handblown glass to maintain maximum optical clarity and long-term appearance.
For different levels of contamination we recommend three cleaning methods.
Required materials
Citric acid solution
Citric acid solution
Citric acid solution
Citric acid solution
Citric acid solution
Quick clean
Suitable for regular maintenance and removal of fingerprints.
1
Apply IPA
Lightly spray a small amount of isopropanol onto the glass surface.
2
Wipe
Gently wipe the surface using a clean Swedish cloth.
3
Evaporation
Allow the remaining IPA to evaporate naturally.
result
Removes fingerprints and light surface contamination.
Recommended cleaning
The recommended method for achieving maximum optical clarity of the glass.
1
Apply citric acid
solution
Lightly spray a small amount of isopropanol onto the glass surface.
2
Rinse
Gently wipe the surface using a clean Swedish cloth.
3
Dry
Allow the remaining IPA to evaporate naturally.
4
Apply IPA
Allow the remaining IPA to evaporate naturally.
5
Final wipe
Allow the remaining IPA to evaporate naturally.
6
Evaporation
Allow the remaining IPA to evaporate naturally.
result
High optical clarity of the glass without streaks.
DEEP clean
Recommended for:
visible mineral stains
stronger contaminationl
ong-term deposits
1
Apply citric acid solution
Spray the citric acid solution evenly onto the glass surface and allow it to act for 10–15 seconds.
2
Wipe
Gently wipe the surface using a clean Swedish cloth.
3
Rinse
Thoroughly rinse the glass with distilled water to completely remove the citric acid solution.
4
Dry
Dry the surface with a paper towel.
5
Apply IPA
Lightly spray a small amount of isopropanol onto the glass surface.
6
Final wipe
Gently wipe the surface with a clean Swedish cloth and allow the remaining IPA to evaporate naturally.
result
Removal of mineral deposits and restoration of perfect optical clarity.
note
In case of heavy contamination, steps 1–4 may need to be repeated.
Important notes
Do not use greasy or contaminated cloths
Do not apply pressure to the glass surface
Isopropanol should only be used as a final step, not as the primary cleaning agent
Safety when working with IPA
Isopropanol is highly flammable.
Do not use near open flames
Ensure sufficient ventilation during use
A brief odor is normal as IPA evaporates quickly
If ventilation is insufficient it may cause dizziness or headache — in that case stop the cleaning process
What if I do not have citric acid
or distilled water?
The cleaning process can be performed without them, but the result may not be optically perfect.
Without citric acid:
Skip steps 1–3 and continue from step 4.
Without distilled water:
Tap water can be used but may leave mineral stains, especially in areas with hard water.
BROKIS recommendation
To preserve the highest glass quality and long-term appearance, we recommend following the full cleaning procedure.
Simplified cleaning methods are suitable for regular maintenance but may not remove long-term mineral deposits.
