Instead of the special "scent free" stuff on your camo?

Does anyone use regular laundry detergent?

I was using All Free and Clear because it is perfume and dye free. Unfortunately, it has an optical brightener that absorbs and flouresces UV light. I switched to Arm and Hammer for Sensitive Skin, after reading the ingredients and not seeing an obvious listing of a brightener. It is also perfume and dye free, and uses baking soda (obviously) to absorb and control odor. I later discovered that it also uses the optical brightener Tinopal. I'm still researching just how much and what UV spectrum that Tinopal absorbs and flouresces, but I haven't had any critters give me the stink eye this season, and I have seen and been very close to plenty.

This thread got me interested enough to do some quick research, and I found a link to a chart of detergents used by folks that wash cloth diapers. This detergent market has decided that brighteners are a potential skin irritant, so it is avoided in detergents used for the cleaning of cloth diapers:
Pretty interesting, especially the amount of detergents that use optical brighteners like Disodium Diaminostilbene Disulfonic Acid (Purex, and several others) and Tinopal (Arm and Hammer and many others.) They all function the same, in that they absorb various wavelengths of UV light, and flouresce them back, causing an increase in the perceived brightness of textiles (and coincidently other treated materials, such as paper.) It has been suggested that deer have the optical and neural mechanism to see into the near UV and UV spectrum of light, but I haven't found any conclusive or comperhensive study that indicates to what degrre of sensitivity or wavelength range they can detect. I imagine that playing it safe, and eliminating products that enhance the flouresence of UV light on hunting clothing is the best bet. It looks like almost all of the "normal" bands have brighteners, so I will have to search for some of the brands recommended on the chart in the link. The good news is that they are not significanly higher in price per load than other detergents, and are significantly less than the UV free detergents marketed and sold to hunters.
