they are fine you don't need to spend billions on MF towels just cut off the tags if they have them

I use pretty much the same as above, except i use cold water on the wash.

If you are washing a very fine thread towel, (Microfibers come in all kinds of weaves and thread count) The hot water could cause some damage to the threads as they are so small the temperature could actually melt them together.

I also use DP microfiber wash. The stuff is great, and I find it lifts all the gunk out of the towels and makes them nice and static full again.

I dry my towels, but on the lowest heat setting as to prevent heat damage.

On towels themselves, I prefer Cobra. They all have removable tags, come in a variety of size, weave, and thread count so you can tailor them to every stage of detailing, and on many have a nice protected edge to not scratch your baby.
