Power scrubbing vs power washing is a question almost every property manager runs into once a parkade starts looking tired. Parkades take more abuse than almost any other part of a commercial or strata property. Oil drips, tire marks, brake dust, road salt, and the occasional spill all end up on that concrete, and none of it goes away on its own.
The question is whether a straightforward power wash will handle it, or whether the parkade needs power scrubbing instead. The short answer: it depends on how long the stains have been there.
Power Washing: Good for Regular Maintenance
Power washing uses pressurized, often heated, water to rinse dirt, dust, and light grime off the surface. On a parkade that’s cleaned regularly, this is usually enough. It clears loose debris, lifts fresh spills before they set, and keeps the concrete looking maintained.
Where power washing falls short is on stains that have had time to bond with the concrete. Oil that’s been ground in by tire traffic for months doesn’t lift with water pressure alone, no matter how hot the water is.
Power Scrubbing: Built for Stubborn Stains
Power scrubbing adds a rotating brush to the pressurized water, providing the mechanical agitation that actually works stains out of porous concrete.
Think of power washing as rinsing and power scrubbing as actually working the grime loose. A neglected parkade usually needs scrubbing first, then can go back onto a regular power washing schedule afterward.
4 Critical Warning Signs Your Parkade Needs Scrubbing
- Oil and grease stains that have set into the surface and don’t lighten after a wash
- Tire marks and rubber buildup near turns, ramps, and stalls
- Salt residue that’s crystallized into the concrete over a winter, leaving white, chalky patches
- No real deep clean in a year or more, even if the parkade gets washed occasionally
If you’re seeing any of these, the power scrubbing vs power washing decision is already made: scrubbing is the right starting point.
How to Tell Which One Your Building Needs
Walk your parkade and look at the stalls and drive aisles specifically. If the concrete looks dusty or lightly dirty but the original surface color is still visible, power washing is probably enough.
If you’re seeing dark, embedded stains that don’t change color even when wet, scrubbing is the better choice. Salt is a common culprit in Metro Vancouver parkades. Chloride damage is serious enough that Environment Canada has a Code of Practice for road salts, and our guide to winter salt damage explains what it does to concrete.
Don’t Forget Where the Runoff Goes
Scrubbing and washing a parkade lifts oil and contaminants that shouldn’t end up in the storm system. In Metro Vancouver, storm drains typically lead to local waterways, so a responsible contractor captures and manages wastewater rather than rinsing it into the nearest drain.
Building a Realistic Schedule
Most Metro Vancouver parkades do well with an annual or semi-annual scrub to reset heavily trafficked areas, paired with more frequent power washing and power sweeping in between. That combination costs less over time than waiting for the parkade to look bad enough to justify a full restoration clean.
Getting the power scrubbing vs power washing balance right is easier with a season-by-season plan. See our year-round parkade cleaning schedule for details.
