A friend of mine asked me to check her through the wall ventilation fan...as it
working properly. Removed the faceplace and the entire ductwork is loaded with
from cooking. (evidentally she does a lot of fried foods.). There is grease
What is a good grease cutter to clean this mess up. Dish detergent didn't make
dent....neither did using a household cleaner. Which cleaners will work.....
very little space to work in...the grease is all over the place and I don't want
get water down behind the wall.
Thanks in advance for your help !!!
I've used degreaser and works well but its a super mess so cover everything
up. The problem is how do you remove all the grease in the duct from the
hood area to the roof? Maybe easier just replacing the duct. The spray can
that cleans car engine and carburetors should also work and you will be able
shoot it up about 5 ft. up in the duct - ware eye protection and have
kitchen well ventilated.
Only if nothing else works...
Easy-Off Fume Free Max oven cleaner will probably work on this kind of
grease, but be careful. The active ingredients of oven cleaners (even the
fume-free) can be dangerous if not handled properly. Wear gloves (neoprene
gauntlets are best) and eye protection. Apply just enough to do the job.
Once the grease has softened, use a putty knife of an appropriate size to
remove the dissolved gunk.
If you choose to try this, make sure you do a thorough job of clean-up.
Oven cleaners can be very corrosive to some surfaces.
Just an idea.
I know what works for me 100% of the time.
But it's usually frowned on by most people.
(unhealthy fumes & possible skin irritation)
Mix a bit of dishwasher soap and chlorine bleach in water.
soak a rag in it and a few quick wipes will take just about anything off.
You might want to try automotive 'Brake Parts Cleaner', available at
your local auto parts store for about $2.50/can under several brand
It sprays on and evaporates oil and grease, so it will get into places
that you may not be able to get into with a rag or brush.
I have been really pleased with how this stuff works for removing oil
and grease and I have also used it to zap an occasional roach, or wasp,
that comes in the house.
Hope this helps you.
Thanks all for your suggestions.... headed out to clean out
the ductwork today. I'll bring a few cleaners along and try
a few in different areas to see how they work. Got gloves, eye protection,
plenty of ventilation and some masking plastic to protect surfaces.
Thanks again for your help and assistance.
...finished the job....it went well....
Simple Green is a good cleaner but just wasn't up to the job of
I picked up something called "Orange Cleaner" by DEPP, which
worked pretty well....took several applications to dissolve all the grease,
but it made life very easy. I liked the idea that it's somewhat organic
and doesn't contain any toxic chemicals.
Brake Cleaner and engine degreaser are definitely two options.... I've had
a lot of luck using them while working on my car...esp...the brake cleaner
just knocks the grease right off without leaving a residue.
Downside of the job.... there is an electric box connecting to the
fan. Box is mounted horizontally and became a grease sump for
all the grease. I removed the box...and literally poured several
tablespoons of liquid grease out of it. Now there was a BX
cable coming up into the box and the grease dripped down into the
cable, corroding the conductor insulation, and leaving several
bare spots on the wires. Cut back over 5" of covering and the
insulation was still soaked with grease and corroded.
Time to replace the cable !!!
Definitely a fire waiting to happen.... this is in a condo where
most units are similar and probably suffer from the same problem.
