Essential maintenance: cords, grip, and anti-fog.
Buying well is half the battle. The other half is maintaining it .
1) Strings: when to replace them (even if they're not broken)
A commonly used rule of thumb: change your strings as many times a year as you play per week.
Example: you play 3 times a week → consider 3 trades per year as a baseline. This helps maintain feeling and control.
2) Grip: when to replace it and why
If the grip starts to slip, loses absorption, or no longer "holds" well, it's time to replace it. (Many players solve this with regular overgrip.)
To get the right grip size from the start, measure your hand and use the matching chart.
3) Glasses/mask: how to clean without destroying the anti-fog coating
The biggest mistake: rubbing the inside of the lenses. This can irreversibly damage the anti-fog coating.
Best practices:
-
Rinse gently after your workout.
-
Avoid detergents (they attack the anti-fog coating).
-
Let it air dry.
4) Save correctly
Keep your glasses protected (in a case/box) to avoid scratches and impacts.
FAQ
Can I use soap to clean my glasses?
In general, it is not recommended because it can affect the anti-fog coating.
Does it make sense to change strings before going out?
Yes, because tension and sensation change over time, even without breaking.
