InteractiveSQUASH uses a highly reliable and precise optical system to detect the exact location of your ball on the wall. Every once in a while it makes sense to clean the sensorbars of that system, especially the lower one where dust accumulates over time.
Information
Utilizing a lint-free cloth, such as a microfiber cloth, is recommended for cleaning. Additionally, equip your vacuum cleaner with a brush attachment to avoid scratching the sensors.
In general, it is not advisable to use any liquid unless necessary, for example, in the case of a spill. If liquid cleaning is unavoidable, it is best to use as little as possible and only use purified water - but be aware: liquid cleaning might break your warranty!
