směs 60 % acetonu a 40 % metanolu
Izopropylalkohol je bezpečný a účinný, ale jeho relativně pomalé odpařování může zanechat na optice zasychající stopy
Doporučujeme použít techniku "ponoření"

Si Mirror: Silicon Glass Gold coated, great reflective index, not good for anything over 80 watts.
Mo Mirror: Molybdenum, very tough but the lowest reflective index,great for 80 watt sources or above.
Cu Mirror: Copper, Below gold Si for reflective index but tough and better index than Mo.
K9 Mirror: Close to worthless gold-coated glass (likely from re-melted milk bottles).
