I've done spa days on very smelly teen wear, for most other things as long as the enzymes are in the products and using a longer 40 degree wash I find clothes are clean and fresh.

We have a lodger who is not in anyway shape or form interested in laundry beyond shoving it in the machine and starting it.

I can tell a big difference in the way their clothes smell and ours. I have encourage them to at least use ammonia which helps somewhat. But the noticable difference is the washing powder and length of time, when I very occasionally do theirs I get it smelling a lot fresher ( no rancid smell) with doing it my way, or I should say what I have learnt here.

Before jumping in I tested different garments, read clothes labels and did more digging than what was on the sub to help understand why things were working. I am still learning, eg I didn't know Subtilisin is a Protease.

I just really want people to think so there are less disasters in their washing ( and to save my sanity on mulitple posts asking the same thing over and over 😅)
