GitLab is Ruby at least, I don’t immediately remember any others but there probably are some

If you’re using powdered detergent, make sure yours doesn’t have zeolite as the water softening agent. It will deposit in the machine, and starts eventually covering the fabrics with a talcum-like powdery substance. It gets especially bad if you either have to use a lot of detergent because of hard water, or are overusing the detergent.

Zeolite was brought in to replace phosphates due to environmental concerns, but it has its own problems with the washing results.

One other thing that often ruins the freshness of clothes for me is overly scented/perfumed detergent. The smell can get quite overwhelming, and contribute to a chemical-y smell and feel.

Just in case someone misreads this, add the vinegar as the softener, so it’s not in the first load that contains the detergent. The detergent is a base, and relies upon that fact to get rid of some of the stains, and vinegar as an acid will neutralize that. Vinegar is meant to be in the rinse cycle when washing laundry, where it can help get rid of any extra detergent by neutralizing it and do any other magic it does.

Also, though I don’t usually encounter them often, do note that vinegar can wash away zinc and silver oxides used for some sterile clothing, and can supposedly damage lyocell.

But overall I second these suggestions. Most times the amounts listed for detergent are far too big, and you can often get by with less.

And we’ve nowadays taken it even further, in spoken Finnish we’ve even got rid of the “hän” and mostly use “se”, which is the Finnish word for “it”. The same pronoun is used for people in all forms, animals, items, institutions and so on, and in practice the only case for “hän” is people trying to remind others they consider their pets human.

Context will tell which one it is.
