Apparently there are some laundry detergents that have fabric softener in them. I think one of them may be Cold Power powder. You may need to read the containers of various brands. The Reject Shop has some but I don’t know the Brand of it. Purity makes a liquid one. The bottle is blue and I think the fabric softener has a pink lid. If you put too much detergent in your washing it may make your clothes hard / stiff. Also if you dry it in very hot sun makes some materials go still / hard. I was also told that too much detergent doesn’t actually make some clothes any cleaner. Also it may not rinse out properly.
