Easy-Off Heavy-Duty vs Fume Free | What’s the Difference?

Easy-Off is a powerful cleaner that’s proficient at cutting through tough grease, oil, caked-on food residue, and similar messes. This product makes cleaning your oven a breeze and practically eliminates the need to put in some elbow grease. But, when it comes to their Heavy-Duty vs Fume Free products, what’s the difference?

The difference between these two products is their ingredients. The original Heavy-Duty formula contains more harsh chemicals that emit powerful fumes and VOCs. The Fume Free version is still an effective oven cleaner, but it uses a different chemical composition to eliminate those unpleasant fumes.

Are you struggling to decide between Easy-Off Heavy-Duty and Fume Free? Well, you’re in the right place because we’re going to do a detailed review of each product so you can understand the difference between the two. Read on to learn about these two cleaners so you can choose the best one for you!

History of Easy-Off

Easy-Off was invented in 1932 by Herbert McCool. This gentleman was working as an electrician at this time and invented the very first Easy-Off product in his spare time. McCool began selling Easy-Off around his neighborhood during the Great Depression, then sadly passed away in 1946.

Following McCool’s death, his widow Doris moved to Quebec and continued manufacturing the product out of her garage. She began selling Easy-Off in major stores in Quebec and surrounding areas.

However, in 1954 she sold the rights to this product to American Home Products after visiting a trade store. The product was again sold in the 1990s and is now produced by Reckitt Benckiser.

What’s The Difference Between Easy-Off Heavy-Duty and Fume Free?

The difference between these two products is their chemical compositions. Easy-Off Heavy-Duty and Fume Free both deliver the same results- eliminating tough messes to leave you with a clean oven. However, the way they achieve those results is slightly different.

The Fume Free product doesn’t emit any harsh fumes. It also requires more wait time than Easy-Off Heavy-Duty formula, but we’ll get into that further in this guide.
