From my "personal" experience. Regular laundry detergents couldn't get out all of the wax, polish, sealant, and oil from my micro fiber towels which can overtime can cause micro fiber towels to get stiff. As well as residue from regular laundry detergents (surfactants)
I myself don't have the time to do a 3-4 step process to wash my micro fiber towels so I use a one step process with a specialize detergent. I still recommend and use "plain vanilla" laundry detergents to get out the soiled stains. And every 2nd or 3rd wash I use a specialize detergent (*there are many out there) that helps breakdown the residue from regular laundry detergent, wax, polish, sealant, and oil. It will however, not remove any heavy soiled in stains.
But I have heard many success with various multi-step processes. Just do what works for you.
