I'm not familiar with the product you reference, but I would be wary of using them. EVERYTHING in our house is laundered with All Free-and-Clear including piggy items. Cavies are sometimes sensitive to laundry detergents (Tide is one of the worst offenders in general) and I simply wouldn't risk any issue. I use the All with a bit of bleach or the All brand of Oxyclean.
Once the wash cycle has finished, I run a very short cycle called "rinse & spin" on my machine and add copious amounts of vinegar to remove any residual odor.
