Topic: Solar and UV Sensors

No one has mentioned surgical alcohol wipes.

Some seem to be up to 99% pure Isopropyl.
Others lower but only contain the addition of distilled water.

Yeah I honestly don't see why they say you need labratory-grade Ethyl alcohol. The atmosphere, as stated by others, is full of "contaminates" and it sits in it day in and out. I would have no problem using Everclear. It makes no sense the things Davis does/says. Sometimes seems like the left hand doesn't know the right over there...

Understood, but you aren't personally guaranteeing my use of Everclear.

Consider Davis' position.  If they say Everclear is OK, and then somebody uses Everclear, has problems, and sues Davis, ............

Remember, you are supposed to use it on the sensors. Not drink it.

I know I can get ethyl alcohol through science supply stores. I do not know if that is available to the general public.

Nasco. Wards.

Although I agree with you that isopropyl should work fine (but no guarantees....) - Davis specifies ethyl alcohol.
