Silicone Stains: Your Questions

Advice from Dr. Laundry
Q.

Is it possible to get silicone stains off from denim and cotton?

A.

It would be helpful to know the source of the silicone. I worked on Armor All and we used a lot of silicone for our protectant and tire products. The important thing here is to use a good product with lots of surfactants like liquid detergent to pretreat prior to washing (apply; rub into stain; wait 5–10 minutes) in HOT water using liquid detergent.

The good news is these are cotton fabrics here rather than a poly/cotton blend, which would hold the silicone much more tightly than cotton.

Don’t forget to check for success before drying as it will make any unremoved silicone much more difficult/impossible to remove. If there is still silicone remaining you can retreat fabrics again.
