Tri suit/short/tops wash/rinse

Please do everyone around you a favour and wash your clothes. Rinsing will not clean the garment and you will have a virtual cloud of stink hovering above you. 

I personally wouldn't buy an article of clothing that precluded me from tossing it in the wash regularly without worries. Having said that, I do try to maximize the life of the garments by washing my workout/race clothes together, always cold water, with a no-residue detergent designed for sport/technical fabrics (or if I'm out I'll use Tide free, or Ivory). Never use fabric softener because it reduces the effectiveness of the moisture wicking properties of the clothing. I usually throw everything in the dryer on a low setting, but never with a dryer sheet for the same reasons as never using fabric softener.  

Considering some of the most expensive clothing in my wardrobe are some of my sport gear, I do try to go easy on them.

I have a seprate hamper for all my technical gear/swim stuff. I was it all seperatly and use only the specialty detergents designed for lycra/dry technical clothing. I have been using "double clean" but I liked the other one in the blue bottle better. They are available at running specialty stores.  The main reason I gave up on using the traditional stuff is detergent w/ fabric softner is the worst thing you can do to your tech fabrics, it clogs the pores and stops it from breathing. So after my underarmor cold gear got mixed in with a load of regular wash it felt like I was wearing a plastic bag for a few washes, no breathability and really hot- Hence the 2nd hamper.  

Reason number 2 for the speciality detergents, go smell your favorite running shirt or shorts- no matter how many time you wash them they always have a funk about them. The specialty stuff lessens the funk or eliminates it. 

 So far after 3 years the tech fabrics have all held up no issues, no pilling. I wash on cld/gentle and tumble dry on fluff no heat then hang/lay flat if necessary. 

 Which reminds me, its laundry day- 

Definately wash; don't just rinse.  We use the Win detergent, which you can get off Amazon (four for $19).  It does a good job with the technical clothing, but it has a rather strong sickly-sweet fragrence that I don't like in my workout stuff.  Although, its better than washing them with regular laundry detergent. 

I've never used scented tech-fabric detergents; IMO kind of defeats the purpose of going out of your way to use a specialty product such as this, which is not supposed to have anything in it that would impede the properties of the fabric, such as softeners and scents.  

If you can't find unscented, try an outdoorsman or hunting goods shop like Cabelas, Bass Pro, etc - they have unscented detergents meant for hunting clothing that are guaranteed to remove any "funk" without leaving any scent (so you will be undetectable to your prey) but are still gentle for tech fabrics. 

I have found the BEST to be SPORT-WASH by Sno-Seal, 18 oz bottle, good for 18 large loads for about $5/bottle. http://www.campmor.com/outdoor/gear/Product___10601  and usually available at my Walmart.
