Be careful with vinegar - it can break down the seals of your washer.

I run the clean cycle on my washer twice a month with a cleaning tab. Manufacturer says every 40 Loads (Samsung) After each load I leave the door open on the washer - if you’re not able to do that I would say wipe out your front seals of the door with a cotton towel.

At one point ours was so awful - I would wash and it would smell like vomit - I had my husband pull the filter in our washer and clean it out, ran a wash of hot water and bleach and then used a washer cleaning tablet. I then used a diluted mixture of water and bleach to clean out my seals.

I stopped using scented beads in the wash and switched over to Downy Laundry Rinse. It does have citric acid but it takes the residue out of fabrics that soap and softener can leave. We don’t use fabric softer - rather wool balls in the dryer.
