Skin Irritation, Hard Water: DIY Laundry Detergent Troubleshooting

Irritation and Yellowing

Lots of folks choose DIY detergents for skin irritation.  But then they’re skin is still irritated!  There are no additives, right?  And why are my clothes getting dingy and yellowing?

Amazingly, it’s NOT additives that get most people.  It’s the pH of the clothes when they come out.  Even with no additives, alkaline laundry can irritate skin.  Skin like a pH of about 6.5.  Laundry water is almost 11.  Professional laundry services have know this for ages.  They “sour” the laundry to get it back to an acid pH that you skin likes.  Acetic acid (vinegar) is generally the SOUR used by industrial services; it also removes rust yellowing and graying.

VINEGAR IN THE RINSE!

So, REGARDLESS OF WHAT DETERGENT YOU USE, help out sensitive skin by SOURING your laundry in the rinse.  1/2 cup in the rinse compartment is more than enough; you might be able to get away with 1/4 cup.  Just play with depending on how well your clothing was rinsed.

Hard Water, Harder Water

Vinegar in the rinse will also help remove hard water deposits on clothing. If you want to use it pre-emptively to keep those particles suspended in the wash water, you can use vinegar or citric acid in the wash. But, if you have any significant water hardness, it might take a lot more vinegar than you want to fool with. Lemi-shine citric acid at $4/72 tsp is cheaper for me than vinegar. 4 cups vinegar equals one tsp of citric acid in water-hardness-suspending-capabilities. The other problem is hard water starts eating away at your diy savings because you have to add so much more washing soda to the mix to keep up the pH. For every cup of vinegar you add to the wash water or for every tsp of citric acid you add, put in 4 extra tsp of washing soda.

So here are my hard water dry detergent mixes for you to try. Tell me how your experiments go!

I Think I Have Hard Water Mix
1/4 c citric acid
3/4 c finely ground soap
2 3/4 c washing soda

Mix in can. Shake a lot first day. Will try to clump. Use 3T per standard load. Vinegar in the rinse.

I Pretty Sure I Gots the Hard Water Mix
1/2 c citric acid
1/2 c plus 2T finely ground soap
2 cups plus 6T washing soda

Same mixing instructions as above, use a rounded quarter cup per standard load. Vinegar in the rinse.

  1. Does anyone know of a good resource for buying citric acid? I’ve checked out local Walmart and two grocery stores and no one knows what it is….lol Thanks

  2. You can find citric acid with the canning stuff right now. I’m not sure if it’s the cheapest way to go, but it should be enough to see if it helps your laundry.

    How much would I add to my HE washer? ‘Cause I know I gots hard water. :)

  3. I forgot to say that I found my small bottle of citric acid at Lowe’s with the canning supplies.

  4. start with half the recommended amount for top loader. tell me if it works. Hard water is why “detergent” was invented.

  5. We have the most awful water I’ve ever seen, it stains the shower stalls rust brown in a couple of weeks after I scrub them with extremely caustic cleaner to bleach them. I mix TSP (trisodium phosphate) into the washload, 1 tsp per load, and this makes a huge difference with the dinginess too. It binds to any iron in the water and takes it out of the clothes and down the drain.

  6. Salt in the wash works great as a water softener (and clothes softener) I used to rinse with vinegar and still come out with rough diapers (vinegar in the rinse helps soften too) then I remembered how bad hard water we have here in denver and went looking for natural water softeners. . . charlie’s makes one that I realized was just essentially salt, ever since I’ve been adding roughly a tsp with each load of plain ol table salt and the diapers almost feel brand new! softer and don’t irritate my girls legs anymore! :) cost is around 50 cents per 75-100 loads. . . works for me!!

  7. I am new to your site and I love it already. Just have one question where do I get or find Washing soda????
    Thanks in advance

  8. Tommie–Thank you! You can usually find washing soda in the laundry aisle of most larger supermarkets.

  9. Any tips for a scented fabric softener? I’ve tried wool dryer balls with essential oil but the clothes don’t smell like the oil at all. I currently use 1/2 cup of vinegar as a rinse but I need something with a scent.

  10. You can either buy citric acid in the laundry section of grocery stores under the brand name Lemi-Shine, use lemon Kool-Aid or bulk Wylers quart of Light (sugar free) lemonade mix from Dollar Tree.

  11. Wow! Mind blown! Your researched responses are EXACTLY what I needed in my search for the best homemade cleaners. Not that satisfaction stops my mind from coming up with new questions . . .

    Let’s see if I can ask this in a way that makes sense -

    You add citric acid to counter hardness, but need to increase the washing soda to keep the overall product basic(alkaline, whatever). What is the neutralized citric acid doing to keep minerals from depositing on clothes? Once neutral, the citric acid is now itself a salt, and I’d think that would increase sediment? Maybe?

    I’ve been using vinegar in my rinse cycle, and while I feel it’s successful, I have my doubts, given that water is naturally alkaline in my part of the country (buffered around 8.5 pH). I’m wondering if I should just add the citric acid to the rinse cycle. Does it dissolve quickly? Should I dissolve it in some distilled or other non-alkaline water and add it as a liquid to the softener dispenser?

    The pH is neutralized, but not the ability to handle minerals. After the acid base reaction, that salt created is still anti-mineral. It’s not the pH that does it. I can’t remember the mechanism (9 months preggers right now) but it doesn’t precipitate.

    You can do either. I calculated the amount of store-bought vinegar needed for neutral water. Depending on your washer, it may be more or less easy to add the acid at different points. Mine has an automatic liquid release during the rinse, so I like the laziness of putting it in at the beginning of the cycle. If you are more attentive than I, I would think you could just put it into the rinse cycle dry…but that’s just a guess. I haven’t watched it dissolve before; I just know it sucks water in from teh atmosphere like crazy and makes clumps, so I would think it would love a liquid environment.

  13. Questions…
    1. Does this get hard in humid weather?
    2. If the salt helps soften clothes, can salt be added to the detergent recipe? How much would one need?
    3. What is TSP and is it harmful?
    Thanks!!

  14. I’ve been using the old laundry recipe for a year and have gotten the bad dingy’s. Old recipe with washing soda AND borax. Will adding citric acid remove the dinginess? I’ll be making a new batch with the new recipe soon.
