Limescale, grease and detergent residue are the silent enemies of washing machines and dishwashers: they settle on the heating element, drum, hoses and pump, reducing wash efficiency, encouraging bad odours and increasing the risk of breakdowns over time. The Wpro DES123 descaler and degreaser (pack of 12 single-dose 50 g sachets, universal and compatible with all models) was created precisely for this kind of preventive maintenance.
What this product does
According to the manufacturer’s data sheet, the formula works with a triple professional action: it reduces limescale deposits on the heating element and internal components (drum, hoses, pump), dissolves grease and detergent residue even in the hardest-to-reach spots, and prevents the formation of bad odours.
When to use it
- Once a month, as regular maintenance: this is the frequency recommended by the manufacturer for ongoing appliance care.
- If you notice persistent bad odours from the drum or tub, even after an empty wash cycle.
- If wash results start to decline: dull dishes, laundry that doesn’t smell as fresh as it should, longer cycles than usual.
- In areas with hard water, where limescale forms more quickly and more frequent treatment is needed.
- After a period of inactivity of the appliance, for example when returning from holiday.
How to use it
- Make sure the appliance is empty, with no laundry or dishes inside.
- Pour the contents of one sachet directly into the drum or the detergent drawer.
- Start an empty cycle at 60°C, without prewash and without adding any other cleaning products.
- At the end of the cycle, leave the door open to air out and thoroughly dry the gaskets.
Manufacturer’s guidance: one sachet a month for ongoing appliance care. Always check the instructions on the packaging, which may vary slightly depending on the model.
Why it’s worth doing regularly
- Extends the appliance’s lifespan, reducing stress on the heating element, pump and gaskets.
- Improves wash efficiency, for cleaner clothes and shinier dishes.
- Prevents bad odours caused by organic residue and stagnant moisture.
- Costs little compared to a repair or replacing the appliance.
