Hi
I use technical Acetone for eyepieces as it leaves no streaks.
Both Bintel brew and Isopropyl alcohol I find useless for eyepieces.
I use the Bintel brew for corrector plate on my SCT.
Be careful with acetone as some eyepieces use plastics that acetone will dissolve. Pentax and TV eyepieces are OK.
