Thick Bleach
Support your washroom cleaning routine with Mirius Thick Bleach. The concentrated formulation cleans and disinfects compatible sanitary fittings and hard surfaces, while its thick consistency helps it cling during treatment. It is suited to planned maintenance of toilets, urinals, sinks and drains where the product label permits use.
The smaller bottle option is useful when taking supplies to individual washrooms, while the 5 litre container provides a larger supply for regular cleaning rounds. Select the size you need from the options on this page and organise the product alongside dedicated washroom equipment in your cleaning store.
For general hard-surface disinfection, Mirius directs users to dilute the product 1:50 in clean water. Remove heavy soiling first, apply the prepared solution using appropriate equipment and allow the contact time required on the supplied label before rinsing. A measured routine helps staff use the cleaner consistently across the areas assigned to them.
The 5 litre W3 product is listed by Mirius as tested to BS EN 1276. Follow the product's application instructions for its disinfecting performance and keep the label and safety data sheet available to the cleaning team.
