I use liquid soap for 90% of my laundry (this one:-
https://www.ocado.com/products/dri-pak-liquid-soap-flakes-302725011 Sorry for the Ocado link, it was the 1st one that came up)..
As I understand it (I'm a chemist but soap isn't my speciality !) detergents contain sulphates, soaps contain carbonates (ionic v aromatic ends of the molecules). Soaps are (allegedly) better for washing surface treated garments: waterproofs, windproofs etc....
They don't strip the surface treatment to the same extent so the "water repellency" is, allegedly, more effective for longer.
I use soaps in my washing machine most of the time so that I can wash the "technical" garments without either having to flush the machine or handwash the "technicals".
From time to time, I use Halo "Sports Wash" but I make sure that it's only normal gear and I also make sure that no "technical" gear goes through the machine before there have been 2 "soap" washes following the Halo.
FWIW, I always wash at 30 deg. C (delicates programme) but I stop it for about an hour to "soak" when the machine has filled initially and all the soap is in the drum with the clothes.
Sometime I rub the detergent into "critical" or particularly "dirty" areas.
On tour (I only stay in hotels/motels sometimes, even, Holiday Inn) I usually wash the bike gear in hotel provided shower gel/shampoo but I also take a small bottle of Halo and wash the cycling shirt and bibs one night each (2 shirts, 2 bibs) in that. It make a huge difference to the "
airiness" smell. It certainly makes me feel better.
I always do the "rubbing" thing outlined above^.
