Cleaning With Household Cleanser
Add 1/4 cup of scented household cleanser to 1 gallon of water, then pour the solution into a spray bottle.
Spray the household cleaner mixture onto the exercise ball. Dampen a washcloth with cool water, then wipe the surface of exercise ball clean.
Let the exercise ball dry outside for two to three days, and then bring it back into the house. Repeat the spraying process if the smell has not been removed from the exercise ball.
Cleaning With Baking Soda
Combine a 1 to 1 ratio of baking soda and water into a bowl, and mix the two ingredients together.
Add the mixture to a damp washcloth, then rub the paste-like substance onto the exercise ball.
Leave the paste on the exercise ball, and then place it outside for two to three days. Retrieve the ball, and then remove the paste from the ball with water. Repeat the process if the smell was not removed from the exercise ball.
