Should I scrub a paver patio after a Vancouver rainstorm?

No, you shouldn't scrub your paver patio immediately after a Vancouver rainstorm. The pavers will be saturated with water, making cleaning products less effective, and you risk driving dirt and debris deeper into the paver surface and joints rather than removing it.

Wait for dry conditions before cleaning your patio. Give the pavers at least 24-48 hours of dry weather after rain to allow surface moisture to evaporate. This is especially important in Metro Vancouver where humidity levels stay high (60-80%) even after rain stops, keeping pavers damp longer than in drier climates. Cleaning wet pavers often just redistributes dirt and organic matter rather than removing it effectively.

The exception is removing organic debris like leaves, moss, and algae that accumulate during storms. Vancouver's frequent rainfall from October through March washes leaves, twigs, and organic matter onto paver surfaces where it can stain or promote moss growth. You should sweep or blow this debris off as soon as possible after it stops raining, even while pavers are still damp. Organic matter that sits on wet pavers for days creates ideal conditions for moss and algae growth, which becomes a bigger cleaning challenge and a slip hazard.

When you do clean, use the right approach for Vancouver conditions. Once pavers are dry, pressure washing with a surface cleaner attachment (1,500-2,500 PSI maximum) effectively removes the dirt, moss, and algae buildup that's common in our marine climate. For stubborn moss growth, apply an iron sulphate-based moss killer first, let it work for 24-48 hours, then pressure wash. The key is timing your cleaning during a dry weather window — ideally 2-3 consecutive dry days so the pavers can dry completely before the next rain.

Consider the seasonal cleaning cycle that works best in Metro Vancouver. The most effective approach is a thorough spring cleaning (April-May) after the heavy winter rains, followed by spot cleaning as needed through summer, and another cleaning in early fall (September) before the rainy season returns. This schedule works with our climate rather than fighting against it, and ensures your patio stays safe and attractive year-round.
