I was in a carpool with my friend’s husband, Josh, who’s obsessed with laundry. We talked about it for 45 minutes. He’s deep in the Reddit r/laundry community, studying detergent chemistry and comparing products.
I learned two things: 1) everyone needs a husband like Josh and 2) I’ve been doing laundry wrong my entire life. Probably you have too.
Three quick wins you can implement today
1. Add citric acid to your rinse cycle
Stop using fabric softener. Add 1-2 teaspoons of citric acid crystals to your softener dispenser instead. Fabric softener leaves a waxy residue that clogs fibers, but citric acid removes detergent buildup and softens without the gunk. Buy it online cheap—it’s used in cooking.
2. Check your water hardness
Visit your town’s water department website and find your water hardness number. If it’s over 120 ppm, your detergent isn’t working. For example, where I live, West LA is 425 ppm. The goal is under 100 ppm.
3. If you have hard water, add sodium citrate
Add ¼ cup food-grade sodium citrate to the drum before clothes. In hard water, calcium and magnesium ions bind to your detergent and make it useless. Sodium citrate fixes that.
Why your clothes still smell like a thrift store
Regular detergent leaves residue. Buildup accumulates on fibers, trapping dirt, sweat, oils, and minerals. That’s the “old soap funk” smell.
Fabric softener makes it worse by adding more waxy coating. Natural detergents lack the enzymes to break down oils. Hard water (over 120 ppm) makes 68% of your detergent useless.
Learn to LOAD your laundry (the chemistry behind it)
The laundry Reddit community calls it LOAD. Four ingredients:
L – Lipase enzymes break down oils from your body and food.
O – Oxygen bleach removes stains and odors without harshness.
A – Ammonia boosts oily soil removal.
D – Detergency (surfactants) that wash everything away
No single product has all four. They’re chemically incompatible for storage. Lipase lives in powders, not liquids. There’s also DNase, which breaks down blood and sweat stains at the molecular level. It’s still fairly new to the market, so most detergents don’t have it yet. That’s why you need multiple products.
The products that actually work
For whites: Tide Powder. It has lipase and optical brighteners that make whites crisp.
For darks: Tide Liquid (no brighteners) + an enzyme booster like FEBU.
For delicates: Spa Day soak with a booster powder for 30 minutes before washing normally.
Every load: Citric acid crystals in the rinse cycle (1-2 teaspoons in the softener dispenser).
If you have hard water: Sodium citrate in the drum. You can find food-grade sodium citrate online, or some people use the citric acid as a substitute (though it’s slightly different chemistry).
Things you’re probably doing wrong
Using natural detergents
They lack the enzymes to break down oils. Your clothes aren’t getting clean.
Using fabric softener
It clogs towel fibers, kills moisture-wicking in athletic wear, and makes clothes smell worse because wax traps bacteria and odors. Stop using it. Use citric acid instead.
Not checking your water hardness
If you have hard water over 120 ppm, your detergent chemistry is completely compromised. This is probably why your clothes feel stiff and dingy.
Assuming one detergent does everything
Tide powder and Tide liquid do different jobs. Use them accordingly.
If you want to level up:
- Rehab Day for clothes with serious buildup or odor
- Enzyme boosters with DNase for blood stains
- Oxygen bleach for brightening without optical brighteners
Start with the three quick wins. Your clothes will feel and smell different immediately.
Your action plan
- Buy citric acid crystals online ($5-10)
- Check your water hardness
- Get Tide powder for whites, Tide liquid for darks
- Add citric acid to your next load’s rinse cycle
- If you have hard water, grab sodium citrate
Don’t get overwhelmed. Just pick 1-2 things you want to improve on and go from there. I simply switched out my natural detergent to Tide and already found that made a huge improvement.
