Solutions that require a little patience
Some techniques, popularized on social networks, rely on time rather than elbow grease. Applying a cleaning product, covering with cling film and leaving it on for several hours limits evaporation and optimizes effectiveness. For extreme cases, disassembling the goggles and soaking them overnight in warm water with mild cleaner can really make a difference.
What if nothing works?
Sometimes the discoloration is related to the wear and tear of the material itself. In this case, even the best tricks can’t work miracles. You can improve the visual appearance, but not always get back to the original white. This is often a sign that it’s time to start fresh.
Once
the glasses have been cleaned or replaced, adopt a little weekly ritual: a quick cleaning with a gentle product is enough to avoid unpleasant surprises. Shiny surfaces are less easy to stain and clean faster, a detail to keep in mind when making a future purchase.
