We offer stain removal suggestions for both Crayola and Silly Putty products. You can find this information by going to Stain Removal.
Specifically, the suggestion for removing Silly Putty from fabric is as follows:
How to remove Silly Putty® & Clay from fabric
-Dull knife or metal spoon
-Liquid dish soap (preferred: Dawn or Joy)
Scrape off as much putty as possible. Use ice cubes to chill the putty making it easier to scrape away. Saturate a cotton ball with rubbing alcohol and blot the stained area. If stain persists, rub liquid dish soap into the stain and wash as normal. Repeat as needed.
Please bear in mind, all the stain removal suggestions we offer have been tested in our laboratory, but we are unable to guarantee the results. We recommend you test our suggestion in an inconspicuous area first.
