I have been using Dirty Labs dishwasher powder for about a year, since we got a new dishwasher, and inspired by some of his older videos on this topic. The performance has been good, no complaints. I don't torture-test my dishwasher like Alec does :). With the powder, I can do the whole some-on-the-door, some-in-the-dispenser thing mentioned here, or just use less for light loads. It is without a doubt not a budget option.

One aspect I like about it is that they have a fragrance-free variant, and even the "fragrance" one is not too bad. A second aspect I like is that it's biodegradable, et cetera. So a bit lighter on the environment, I hope, and the SDS is prominently available on the website.

I think another thing which is under-appreciated is that you need to know how to do the basic cleaning chores for your dishwasher-- for example if it has a filter, learn to clean it! Otherwise its ability to clean will probably be compromised.
