RINSING & MECHANISM CHECK
Once the timber is clean, we carefully rinse the surface to clear away any remaining residue. During this stage, we also ensure the moving parts are totally clear of obstructions so the cowl turns smoothly.
NATURAL DRYING & INSPECTION
Finally, we allow the structure to dry naturally in the wind. We perform a final visual inspection to guarantee your oast cowl looks completely refreshed, vibrant, and perfectly clean.
