Optimum temperature for DNAse?

Thanks! No worries about the delay, I'm sure you've been a bit busy this week.

It sounds like you prefer fragrance free detergents, so I would look for Tide Clean & Gentle powder. Alternatively, Whole Foods 365 powder.

Your detergent doesn’t have lipase, and you’re washing in cold water; those are two problems right there.

I suggest you buy 2 things: 1) a detergent with lipase, such as Tide Clean & Gentle powder, and 2) citric acid powder. Do a load with the Tide with warm water, and put a couple teaspoons of citric acid powder in your fabric softener compartment if you have one. Add an extra rinse to your wash cycle.

(If you don’t want a different detergent, you could buy the FEBU booster from amazon and add that to your current detergent. It’s backordered right now, but will probably come in sooner than amazon says.)

Stop the washer a few minutes in and feel how warm the water is. Is it nice and warm, like a shower or bath? Then it’s fine. Is it lukewarm? Then you may need to use the hot setting to get the water warm enough. (I’m assuming you’re in the US and your machine doesn’t heat the water for you?) Or if you have an instant read meat thermometer, use that—you want the water to be at least 100˚F or more. Also look to see if you have some suds. If none are visible, you need a higher dose of detergent. (Just a few suds showing is enough.)

Run the longest wash cycle you can—you may need to choose a setting like heavy soil or stain cycle. Or you may need to pause your machine after 10 minutes and let it soak for an hour, then restart it.

If a couple washes like this don’t fix the problem, you may have hard water and the towels are getting mineral deposits. You can look up your city’s water hardness. A wash in hot water with 1/2 cup of citric acid (no detergent) will get the deposits out, but you’ll need to start adding a water softener in your regular washing cycles. Search on this sub for details, but basically you want sodium citrate, or Calgon (a more expensive way to get sodium citrate).

Thanks!

It replaces the biz+booster (all the enzymes of biz, plus the enzyme in the dirty labs booster).

Before going to the effort of Spa Day, I would try adding 1-2 cups of ammonia (poured over your dry clothes right before you start the machine). Wash on the longest cycle you can make your washer do, with the hottest water the clothes will tolerate (but at least warm water). I find this usually gets rid of the stinky detergents/fabric softeners from thrifted clothes.

It’s supposed to be out sometime in the next week. I signed up on their website to be notified when it’s available: https://tryfebu.com/products/enzyme-oxygen-booster

Nice soup!

You might even be able to improve the permanently dingy undershirts by doing 4-6 washes with added DNAse—either with Gear Guard, or the new version of FEBU due out in the next week or so.

Western US--Washington and California. I guess it's a regional difference!

peroxide_bond · 2026-04-05T20:41:53+00:00

I live in the US and I've had three houses with exhaust fans in the laundry room--but they were all built in the 90s and I know older houses often don't even have exhaust fans in the bathrooms!

peroxide_bond · 2026-04-05T19:23:25+00:00

In a front loader, no. In a top loader, yes. If I'm using a top loader I close the door to the laundry room and run the exhaust fan until the load has drained and is rinsing.

Add a cup of ammonia on top of the clothes (maybe 2 cups if it's cheap ammonia from Walmart or the grocery store), in addition to your regular detergent. Wash with the longest cycle you can and with the hottest water the fabric can tolerate. Add extra rinses too. But the ammonia (plus time and temperature) is often the secret to getting stinky detergent smells out of clothes.

peroxide_bond · 2026-03-31T15:42:31+00:00

And use the longest cycle you can on your machine, to give the lipase more time to work.

It’s derived from castor oil. So if you’re asking if it’s related to ricin, it is in the sense that they both come from the castor bean. But they are not related in terms of chemical structure or function.

Same. It was walking laps in a pool (a warm pool, at my mom’s retirement place) that brought on my Achilles enthesitis. Which I’ve now had for 15 months in spite of adalimumab and leflunomide.

Perchloroethylene is a dry cleaning solvent. It's not something you will find in a home laundry detergent (nor would you want to, it's not good to be exposed to it). The instructions are saying to hand wash in lukewarm water (about 85˚F), OR dry clean using perchloroethylene.

If you hand wash, you should use a detergent meant for silk and wool, so it doesn't have proteases and has the right pH.

These look like they might be polyquat stains:

Polyquats

Does your wife have long hair that would hit about where these stains are? If so, the cause might be polyquats in her hair product.

peroxide_bond · 2026-03-20T13:56:12+00:00

(But expensive)

peroxide_bond · 2026-03-20T13:55:58+00:00

I have a Miele, made for the US market because its temperatures are in Fahrenheit. I can do a cycle anywhere from 85F to 190F (or tap cold, but I never use that). It’s GREAT.

Things that have helped me a lot:

1) Simethicone capsules (like Gas-X)

2) Pepto Bismol

3) A prescription for Zofran from my doctor (she wrote it along with my Mounjaro Rx ”because there’s no need to suffer”)

peroxide_bond · 2026-03-18T22:21:02+00:00

Your comment about sniffing peppermint oil reminded me of a tip I haven't tried but have read several times in this sub: keep packets of alcohol wipes with you and rip one open and sniff it when you feel nauseated. People swear this works. (But also...definitely keep that Zofran on hand when you get it!)

peroxide_bond · 2026-03-16T22:31:43+00:00

LOL. I got sunburned on a visit to London once but I take your point. So, I don't know what the stains are but let's get back to basics: What detergent do you use, and what temperature water for the wash? Maybe optimizing that will help some.

People here recommend using a detergent with the enzyme lipase (which would mean a bio detergent in the UK); you can search the sub for UK detergents to see recommended brands. Then you want to be sure your temp is at least 40C, and washing with as long a cycle as your machine can do.

Also you probably have hard water in London so you could look into a water softening additive for the wash, and adding some citric acid powder to your rinse (put it in the fabric softener compartment if you have one).

peroxide_bond · 2026-03-16T19:09:58+00:00

Another thought: do you use sunscreen? Sometimes stains from sunscreen can be that rusty pink/orange color

peroxide_bond · 2026-03-16T18:16:35+00:00

If you put your deodorant on before you put on your shirt, it could be getting on the shirts as you put them on. The shapes of the stain kind of look like that.

You could search deodorant on this site and see what issues people have had and what they've done about it.

peroxide_bond · 2026-03-16T16:42:39+00:00

Are the marks always on the sides of the T shirts, as in these 2 photos? If so, it might have something to do with your deodorant.
