First time post for me and first time deer hunting in a long time. Was wondering why everyone was seeing and getting deer but. Started searching the forum and low and behold it was my scent and the fact they could see my clothing. Figured out the scent part, but was curious about the UV optical brighteners. I saw how expensive the hunting specific unscented laundry detergents were and wondered if regular unscented detergents would work. Looked on the Tide\P&G website, clicked on Contact tide and searched on UV brighteners. It returned a FAQ answer that stated there are several products they sell that are unscented and contain no optical brighteners. web address and FAQ response below.

Contain optical brighteners?
Question
Do you make any laundry detergents that don't contain optical brighteners?
Answer
Optical brighteners are commonly used in laundry detergents to enhance fabric appearance and maintain whiteness or brightness. We understand there may be situations in which a detergent without these brightening agents is needed. The following detergents do NOT contain optical brighteners:
Bold Powder
Cheer Original Liquid
Cheer with Bounce Fresh Linen Scent Liquid
Cheer Free & Gentle Liquid (but not HE)
Cheer Dark Liquid
Cheer Powder (all versions)
Tide Free Liquid (except Tide HE Free)
Hope this helps!
