Was once told its a problem to leave Arba Minim soaking in water for 24+ hrs due to "kovush kemevushel" they become posul.
What is kovush kemevushel?
Something soaked for 24hrs is considered cooked.
Is a wet towel considered kovush? Would it matter if you use it the same time every day (so it wouldn't sit there for 24 hours)? (over Shabbos would still be an issue)
I buy 2 sets of each - you can get them for really cheap.
link?
i do wet/ damp towel covered in foil in the fridge
