I use it in my dishwasher. My understanding is that it is the old, old Cascade that worked so well but was taken off the market for being too strong. I like it very well. Maybe I'll try it to clean my washing machine. Can't hurt!

hisown, it was likely removed because of the amount of phosphates, chlorine bleach, and later with the ban of phosphates.

From what I understand, as long as there is cyanuric acid present in the solution, the Sodium dichloroisocyanurate will continuously release hypochlorite to replace the other hypochlorite when it converts to another product, or is given enough time to break down. From what I read, a solution like the one I produced can last for days.

I would not use this to clean a front load washer. It is harsh for one, and not all front load washers heat the water properly on designated "clean" cycles. You could end up with a glob of undissolved Cascade somewhere. Citric acid based descaler products would be best. I use Finish Booster, 2tbsp for my Miele W1 on "clean" cycle. I have had several front load washers and none of them actually even sanitize the drum using a clean cycle...the Miele W1 does. Bleach as a cleaning agent is what some brands call for in a clean cycle, if water is not heated for clean cycle use that. Or use a citric acid based descaler on a hot cycle. Miele does sell a descaler, I find the Finish Booster to be similar and cheaper. 2tbsp per load in a dishwasher, so I use same amount in my Miele W1.

Lemi-Shine laundry/washing machine cleaner is the best and most inexpensive I have found locally. Miele descaler is fine too, but its more expensive and harder to find. Need a washer that heats water HOT to make citric acid work well.
