Cleaning glasses

For easy cleaning, you should have: 

• a bucket of clean, warm, lime-free water (demineralized water)
• with a spray of dishwashing liquid
• a non-abrasive sponge or a nozzle with a sponge
• a scraper
• clean cloth to dry the scraper
• a large cloth

Here is the method:

• place a large cloth on the inside to collect the drips on the floor
• rub the glass with the wet sponge
• pull the liquid with the scraper, American "S" method
• systematically dry the scraper before resting it on the glass
• remove drips by dabbing with a cloth
• if labels or dirt, use your nail, it does not scratch!
• avoid working in direct sunlight, as water evaporates too quickly
• avoid hard water that will leave white traces
• avoid scrapers that will scratch the glasses
• And if you have Structural or Pollux windows, dirt can't get stuck on sills and cleaning becomes a pleasure!

For the first cleaning at the end of the construction work, it is essential to wet the glasses a lot before rubbing them. The construction dust has stuck to the glasses and you may carry it away with your sponge, which then turns into sandpaper.
