You can get Pam residue off your pans with baking soda and water.
To get the Pam residue off your pants mix equal parts of baking soda and water together to make a paste out of the baking soda.
Then apply the baking soda and water paste to the pans and then use a non abrasive sponge or brush to scrub the pan which will then remove the Pam Residue from the pans.
Then wash the pans again using some Dawn Dish soap which helps to ensure all the Pam Residue is off the pans.
Before adding the baking soda and water paste to the pan make sure any other food residue or particles are off the pan.
The baking soda and water paste should easily take the Pam Residue or any other oil residue off the pans.
I use this remedy all the time for cleaning oil residue and Pam Residue off my pans and it has always worked great.
