Daily Fryer Cleaning Steps
1. Filter the Oil (or Dispose if Spent)
Let oil cool to safe temperature (~50–60°C).
Use oil filter machine or carefully pour oil through a filter cone into a clean container.
Store filtered oil in a labelled, covered container.
2. Remove Debris
Use a fryer scoop to remove loose food particles from the fryer well.
3. Wipe Exterior
Spray BS EN 1276 food-safe degreaser on the fryer exterior (cool to the touch).
Wipe with a damp cloth, focusing on handles, knobs, and splashes.
4. Clean Baskets
Soak baskets in hot soapy water.
Scrub using a nylon brush, rinse thoroughly, and allow to air dry.
🔁 Weekly Deep Cleaning ("Boil Out")
Always refer to the fryer manufacturer’s manual before boiling out.
Step 1: Drain Oil Completely
Ensure oil is fully drained and discarded or filtered/stored.
Step 2: Scrape & Rinse Interior
Use a fryer cleaning brush to remove hardened oil and debris.
Step 3: Fill with Hot Water + Degreaser
Fill fryer up to oil line with hot water.
Add fryer-safe degreasing solution (follow dilution instructions).
Step 4: Boil Out
Turn fryer on and bring water to gentle boil (10–15 mins).
Turn off and let cool fully.
Step 5: Drain, Scrub, and Rinse
Drain water safely.
Scrub interior walls with long-handled brush.
Rinse with fresh, clean water at least twice.
Step 6: Dry Thoroughly
Wipe down with clean cloths and let air dry.
Moisture left behind can cause oil splatter or degradation.
Step 7: Refill with Fresh Oil
Pour in clean, high-quality oil and preheat fryer as normal.
Record oil change in your maintenance log.
