| It’s Time To Talk About An Unpleasant Subject: Scrud | |
| |
| Scrud is a colloquial term for the residue that can build up in washing machines. While HE machines are most susceptible to Scrud, any machine is capable of developing it. It’s a combination of mineral, detergent, soap and fabric softener residues, along with fugitive dye, lint and soils. Scrud is not generally harmful to human health, but it’s disgusting AF and it can smell - both due to the contents and because Scrud supports bacterial growth including biofilms. Scrud often has a waxy, flaky texture that “feathers” when compressed. Other forms can include granules or sheets. | Scrud is a colloquial term for the residue that can build up in washing machines.

| What Causes Scrud? | |
| |
| The biggest contributor to Scrud is naturally-occurring minerals in tap water. The higher the calcium and total alkalinity of wash water, the more Scrud forming potential. When minerals start to build up, it’s usually not in isolation, though, especially in North American machines without boost heaters. There’s usually a soap or detergent component. Soaps (made from alkali-treated fats and oils) are especially notorious for causing Scrud, and soaps are now found in many mainstream washing products such as All Free & Clear as well as “green” products and boutique fragranced products. Fabric softener can also contribute to Scrud formation. As the Scrud forms, it traps dye, soils and lint in the layers, and any oils or fats can turn rancid. Bacteria can feed on these trapped soils and oils. | **Or around things like the tumble vanes:** |

| Avoid soapy products and ingredients - anything with cocoate/oleate/palmate/sunflowerate ingredients = bad news if you have water prone to Scrud formation. Same with liquid castile soaps. This rule especially pertains to homemade “detergent” hacks that use hard soaps like Fels-Naptha, Zote or Ivory - these are fine as spot treaters, but don’t rinse away in automatic laundry machines. | |

| Consider a citric acid rinse product as discussed at r/laundry/comments/1nhdr0r/ - these work to remove the minerals that are required for Scrud formation and help rinse away excess detergent.

| Citric acid is the best way to clean Scrud from your machine, and various companies sell it to do just that, at a premium price. One has the audacity to tell you not to use citric acid for machine cleaning and descaling, and then literally has a link on the same page to sell you their $15/dose descaling product. Which is 85% citric acid. The brass ones on some marketing departments. | Citric acid is the best way to clean Scrud from your machine, and various companies sell it to do just that, at a premium price.

| Starting from a new or cleaned machine, you should run a citric acid cleaning cycle somewhere between every 30-75 cycles, depending on your water hardness (harder, towards the more frequent softer to the less-frequent) | Starting from a new or cleaned machine, you should run a citric acid cleaning cycle somewhere between every 30-75 cycles, depending on your water hardness (harder, towards the more frequent softer to the less-frequent) |
