 almost all chemical/ organic filters are yellow becouse they need to absorb ultra violet rays, and as u see- yellow absorbs violete color (the only organic filters i know to have white color are: tinosorb m - white powder which works like in-organic (mineral) & organic filter in the same time, second organic uv filter i know to have white color is HAA299 - aka basf competitor to loreal's mexoryl 400 / mce, and the third one is uvinul a2b)

+===== - Scrud: The Dirtiest Word In Laundry =====

I'll include the image links and a description. Some are quite gross, click with caution if you have a weak stomach for slimy things.
+=== 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.
+**Warning:  Sensitive Readers May Be Terminally Grossed Out:**
+Here are some images of Scrud posted here in r/Laundry by other Redditors.
+**You may first notice Scrud on your textiles:**

+=== 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.
+=== What Can I Do To Prevent Scrud? ===
+  * Wash on hot periodically.  Scrud is more soluble in high wash temperatures.
+  * 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.
+  * Don’t use liquid fabric softener you can’t see through or scent beads that promise to soften
+  * Consider a citric acid rinse product as discussed at [[https://www.reddit.com/r/laundry/comments/1nhdr0r//|r/laundry/comments/1nhdr0r/]] - these work to remove the minerals that are required for Scrud formation and help rinse away excess detergent.  They also make your laundry feel and smell great.
+=== How to get rid of Scrud: ===
+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.
+/2 cup / 125 mL of cheap citric acid powder right in the drum, and either the machine clean cycle (preferred) or the hottest / longest possible wash cycle (with “Sanitize” enabled, if your machine has it) will get your machine clean and Scrud-free by dissolving mineral and soap/detergent buildup.     If you have a top loader without a machine clean cycle, use a high-fill hot wash setting, and once agitation starts, pause the machine for an hour to allow the citrate to do the work, then allow the cycle to finish.  Follow your machine’s instructions for filters and strainers that may need cleaning after this treatment.    Check the drum for chunks after the clean cycle and wipe them out before repeating if they’re present.  No sense trying to dissolve something you can wipe away.
+Machines that haven’t been cleaned regularly, have been exposed to the bullshit that is “homemade detergent” or have had other soap-containing products used in them may have a severe layer of Scrud buildup.   The telltale sign is that they will foam during a cleaning cycle with citric acid.  I cannot be emphatic enough - citric acid does not foam.  You can shake and shake and shake a citric acid solution, and the bubbles disappear instantly.  If there’s foam in the machine at any point in the cleaning cycle, there’s still retained Scrud getting removed.  The absolute worst machines can take 8-12 cleaning cycles to get completely clean and suds-free.  Be patient.  The anti-Scrud chemistry works as inevitably as Jennifer Lopez ruins a feature film.
+Once your machine has achieved a clean, suds-free state, a  final cleaning cycle with just household chlorine bleach, in the dose recommended by your machine’s manual will provide some additional disinfection coverage to those shiny clean parts.  It’s a bonus round, but worthwhile.
+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)
+There's more information about sourcing citric acid and discussion of the various price and purity options at r/laundry/comments/1nhdr0r/.
+**Editors Note:** See your washing machine manual for machine maintenance, how to clean your machine, if you have a filter that needs to be cleaned, and what type of product to use to best clean your machine.
