After a rainstorm, your synthetic lawn may look fresh and clean, but water and contaminants may become trapped in the turf layers and potentially lead to unpleasant smells, fungal growth, or pooling water if not properly maintained. The good news is that post-rain turf care requires minimal effort and doesn’t require heavy equipment or harsh chemicals.

Start by checking for standing water. If water lingers longer than 3–4 hours, it could mean your infrastructure has become compromised. Assess the underlying substrate and ensure the gradient directs runoff away from your foundation.

Next, lightly rake the surface using a specialized turf rake. This helps return the grass to its upright, realistic appearance while promoting circulation that reduces dampness. Avoid metal bristles, which can damage the synthetic material.

If you notice leaves, twigs, or dirt washed onto the surface, remove them with a soft-bristled push broom. High-pressure washers are not recommended as they can dislodge infill or stretch the backing.

If pets have used the lawn, clean spots using a diluted vinegar-and-water mix to neutralize odors. You can also apply a thin layer of activated charcoal, let it sit for 10–20 minutes, then work it into the fibers and flush with water.

Always let it dry naturally before use after cleaning. To prevent future issues, consider scheduling a monthly inspection of your water flow and material density. Top up infill if it has settled or been displaced. Limit walking on wet turf, 熊本 人工芝 業者 as this can cause compaction.

With consistent, gentle care after each rain, your synthetic lawn will stay bright, odor-free, and long-lasting for many seasons.
