Vaseline is a brand name of common petroleum jelly, a product with an oil base. If vaseline soils clothing, follow careful pretreating procedures to remove the vaseline. After pretreating the stain with several different solutions, presoak the stain and wash the garment with detergent.
Use the plastic putty knife to remove as much vaseline from the clothing as possible, scraping along the surface of the clothing with the blade. Do not scrape too hard or you could damage the fabric.
Saturate the affected area with isopropyl alcohol. Dab at the stain with the white towel. Continue dabbing until you have removed as much vaseline as possible.
Mix 1 tbsp of dishwashing liquid with 236ml of warm water. Fill a spray bottle with this mixture and spray the stained area generously to saturate it. Dab at the stain with the paper towel to remove any vaseline that remains on the clothing.
Fill the other spray bottle with hydrogen peroxide. Spray the stain generously with the hydrogen peroxide. Allow the area to dry completely.
Apply the laundry presoak product to the stain, following the directions located on the package. Allow the presoak product to set on the garment for approximately 15 minutes (you should also consult the package for the recommended standing time).
Wash the garment with washing powder, following the washing instructions on the care label on the garment. Remove the garment from the washing machine and visually inspect it to see if the stain remains before drying. If the stain persists, repeat steps three through five.
Do not dry the garment in the dryer until you have completely removed the vaseline stain because the heat of the dryer will further set the stain, making it impossible to remove.
