KD-590 · Warehouse Floor Cleaner

The product in detail

Kärcher KD-590 targets warehouse soil and dense dust on compatible concrete. The manufacturer page lists a phosphate-free formula intended for Kärcher machines; the catalogue describes daily cleaning of finished or unfinished concrete. On sealed or polished slabs, test whether sheen is preserved after drying.

Loosens warehouse soil on compatible concrete. After drying, check that the cleaner’s alkalinity and the pad preserved the finish’s sheen.

Listed specifications

Values come from the supplier documentation consulted. Performance depends on conditions and configuration. The supplied reference’s container or nameplate and manual determine its use.

Surfaces and compatibility

For oily and greasy soil on explicitly permitted surfaces. Distinguish surface soil from oil absorbed into porous material and identify any sealer, paint or floor finish.

The web page lists pH 10.5 and the 2025 catalogue lists pH 12.9. The catalogue foam table and descriptive text also differ. Confirm the current formula before setting the washing procedure.

Preparation and use

Identify the slab coating. Test at the label dose before machine scrubbing and recover the solution.

1. Remove loose debris and collect free oil using the site procedure.
2. Read the label and SDS for dilution, protection, ventilation and incompatibilities.
3. Test at the intended dilution. Check for finish softening or colour change.
4. Apply, allow contact time and agitate only as instructed; prevent solution drying on the surface.
5. Recover solution and rinse as directed. Use the approved disposal route for greasy wastewater.

Care and storage

Clean dosing equipment and splashed surfaces as instructed. Keep containers closed and labelled. If the floor remains slippery, check grease recovery and rinsing before reopening it.

Limits and things to check

A stronger concentration may damage the floor without improving results. Approval for concrete does not establish suitability for aluminium, wood, paint or food-contact materials.

Equipment, accessories and options

Auto-scrubber, consumables suited to concrete and sealer, measuring device and recovery.
