One option, is to take your microfiber collection to a local Laundry Matt and use their washers and dryers for your car detailing towels.
I didn't start this thread and I've never boiled any type of towels and have never recommended it as a best practice and at this time I don't ever plan on boiling towels.
For as long as I've been detailing, that includes before microfibers were the new norm, I've used Tide Laundry Detergent, powder most of the time, and used normal top load washers and dryers and I've never had any problems wiping anything off of anything.
Everyone's always encouraged to find a way that works best for them, and a segment of online enthusiasts tend to like to take things that should be very simple and make them as complicated as they can, nothing wrong with this, buy my personal style is use the
KISS system,

From experience, you want systems for common tasks that are easy to duplicate over and easy to start and finish.
Here's my simple tip that I practice myself...
Start washing machine, set the water level to small or medium, select the
HOT setting for water temperature, add your soap, either liquid or powder and let the washer fill and agitate the soap solution into a thoroughly mixed soap/water solution.
AFTER the soap and water have become a
thoroughly mixed solution,
THEN then add your microfiber polishing cloths and turn the wash timer back to the maximum time setting.
Let the washer run through it's cycle. Never just add the microfibers and the soap solution together at the same time because by the time the soap mingles through the microfiber and mixes thoroughly the wash cycle will be almost over.
If you like, repeat the above and wash the microfibers a second time. I do this often and when I've peeked in on the wash solution it's sometimes surprising to see how much residue is still coming out of the microfibers as you can see it by the color of the water.
After the wash cycle is over, place the microfiber polishing towels in the dryer on the normal setting or the setting for cotton towels and dry them.
Remove towels from dryer, fold and as your folding them separate them into their appropriate groups, (If you washed towels from different groups), and then store in a place where they will not become contaminated.

The above is a fairly normal and simple process that is easy to duplicate over and over again and the results must work because all my cars come out looking good after wiping them with microfiber polishing towels I've washed and dried using the above system.
