How to Best Clean Fryer Hood Filters

Q: Is there an easy way to clean the filters from my hood? Caustic degreasers make the aluminum turn brown and are dangerous to work with.

A: One of the most efficient ways to clean the hood filters is to do it when you are already cleaning the fryer with a mild alkaline detergent.

  • Drain the fryer and refill with water. Add 1lb. of Alconox PFS® concentrated detergent to the water and stir to dissolve.
  • If the fryer has a “Boil Out” or “Simmer” setting, use that. If not, set the fryer to 190 degree F.
  • Now take the filters from the hood and place them in the hot detergent in the fryer. If they don’t completely submerge, don’t worry – just let them soak for 10 minutes and then turn them over for another 10 minutes. While they are in the detergent, use a long-handled nylon brush to remove the grease buildup.
  • Carefully remove the filters from the detergent and spray them off in the sink with fresh water. Then use the same brush to remove the grease buildup from the fryer.
  • Drain the detergent solution from the fryer, rinse with fresh water, and dry completely.

Now you have a sparkling clean fryer (which will help the fresh oil last much longer) and sparkling clean filters for you your hoods.

A win, win for efficiency and cleanliness.
