All-purpose has its limits. WoldoClean goes beyond everyday cleaning tablets with dedicated products for coffee machines, robotic mops, ovens and drains. Coffee oils and limescale require different treatments. So do routine drain maintenance and stubborn blockages.
Inside the WoldoClean range
- Cleaning, in tablet form – 40 all-purpose tablets make up to 200 litres of cleaning solution, depending on dilution. Separate dissolvable toilet tablets are formulated for ceramic toilet bowls.
- Two sides of coffee machine care – phosphate-free tablets remove coffee oils from compatible brewing units, while the liquid descaler targets mineral deposits in the water system.
- Floors and tougher surfaces – a concentrated cleaner for compatible robotic mops, diluted at 15 ml per 300 ml of water. For baked-on cooking grease, there's a separate oven and grill cleaner supplied with an application brush.
- Drain care, two ways – an enzyme-based gel for regular maintenance and a more intensive Power cleaner for blocked household drains.
