Pre-clean inspection and safety setup
Start by reviewing the kitchen layout and identifying every grease-producing area connected to the exhaust system. Check hoods, duct runs, fans, filters, and any accessible dampers so you know where buildup tends to collect. Before Kitchen exhaust cleaning work begins, confirm the power isolation method and ensure the extraction fan can be safely locked out. This prevents accidental start-up while you remove components and handle degreasing chemicals.
Next, prepare the workspace to control mess and protect surfaces. Lay down absorbent pads or protective sheeting around the hood zone, and protect floors and nearby appliances from drips. Gather the right equipment such as non-corrosive degreasers, brushes sized to duct diameter, and appropriate scrape tools for heavy carbon. If water is part of the process, confirm drainage routes and ensure spill control is in place to avoid contamination.
Step-by-step extraction system cleaning checks
Use a structured approach that follows airflow from the hood to the discharge point. Remove filters and pre-screens so you can inspect them for saturation, warping, or damaged mesh. Clean hood surfaces by loosening grease Water tank cleaning deposits and wiping to remove residue rather than just spreading it around. Inspect fasteners, hood seams, and corners closely, because residue often hides in creases where wiping isn’t visible.
Then move into duct and fan components using a method that matches the level of contamination. Verify duct joints for leaks or gaps, since grease can escape and re-accumulate after partial cleaning. Clean fan blades and housings thoroughly, paying attention to imbalance risk caused by uneven deposits. Finally, check that dampers move freely and that airflow pathways are clear so the system can ventilate effectively without restriction.
Water tank cleaning and residue management
If your cleaning method uses water tanks or wash systems, treat them as part of the hygiene process rather than optional equipment. Inspect the tank for sludge buildup, emulsified grease layers, and sediment that can reduce cleaning performance. Remove debris and rinse thoroughly, then sanitize according to the product instructions so residues don’t redeposit onto cleaned parts. This step is essential for consistent results, especially when multiple hood sections are processed in one service visit.
Manage waste responsibly by separating grease-laden water from cleaner rinse streams where possible. Use proper containment to prevent spills and avoid draining residues into unsuitable waste lines. Keep clear records of what was removed, including filter condition and any unusual blockages encountered. These details help refine the next maintenance plan and reduce the risk of recurring hotspots in the ductwork.
