The white mark on dark clothing and the powder feeling in the stitches are commonly referred to as “laundry powder Residues”. It may come from the insufficient dispersion of the powder, or from excessive detergents, fibre crumbs from clothing friction, or sediment accumulated in washing machines. It is usually more effective to distinguish and then process than to directly increase the number of bleachings.
1. Reduction of one-time usage
When the actual quantity of clothing is less than full drums and the stains are not heavy, the usage should also decrease. Excess detergent not only increases the drift burden, but may also re-encumber the sludge on the fibre surface. Tests can be performed twice in a row at lower usage and other conditions remain unchanged.
2. Inspection of delivery methods and water temperature
Extremely low water temperatures, ultra-short programs or pressure of powder directly under heavy clothing may affect dispersion. A small amount of water may be used to disperse the powder, before being dropped according to the washing machine description. Do not raise yourself to the unsuited heat of the fabric.
3. Leave room for clothing to flip
When overstretched, the flow is difficult to pass through, and the detergent is difficult to evenly reach and discharge. In particular, thick towels, beddings and protective clothing can easily form local packages. A moderate separation between large and small items is often more effective than increasing product use.
4. Inspection procedures, detergent boxes and machines
- (a) Whether the short procedure is suitable for the current level of clothing and stains;
- Whether the detergent cartridge is damp or blocked through passage;
- Whether filters, ducts and inner cylinders need cleaning;
- The drainage is smooth.
What about the white print?
Smash or brush the surface dust, and then wash it alone with fresh water. Do not insert detergents repeatedly before determining the cause. If it occurs only on a particular piece of clothing, other reasons such as hair loss, softener spots or pocket paper chips should be examined.
