### Required Materials

* Few clean microfiber cloths.
* Warm water.
* Mild liquid dishwashing soap.
* Spray bottle with clean water.
* Spray bottle with mild soapy water.
* 99% Isopropyl alcohol.

{% hint style="warning" %}
Avoid using hard water when cleaning the sensor.
{% endhint %}

{% hint style="warning" %}
Do not use acetone to clean the window. It will embrittle the polycarbonate. 
{% endhint %}

{% hint style="warning" %}
Do not wipe dirt directly from the sensor. Spray it off with warm water first.
{% endhint %}

### Procedure

1. Using the 99% isopropyl alcohol and a clean microfiber towel, wipe away bugs/mud/debris from the sensor.
2. Spray the sensor with warm, mild-soapy water and gently wipe the sensor with a clean microfiber towel. Wipe along the curve of the sensor, not top-to-bottom (think moving with the grain).
3. Spray the sensor with clean water to rinse off the soap and dry with a second microfiber towel.
