Mayonnaise itself normally does not have much color, but it contains oil and eggs, both of which can stain things easily, partially because of the oily film left behind.

Below are instructions for how to remove mayonnaise stains from clothing, upholstery and carpet so you can just enjoy your mayo without worry.
Step 1: Scrape off any excess mayonnaise from the fabric.
Step 2: Rinse the stained area under cold water to get out as much of the mayonnaise as possible.
Step 3: Pretreat the stain with a laundry prewash stain remover.
Step 4: Launder in the hottest water allowed for the fabric to thoroughly remove the stain and the oil.
Hint: Make sure the stain is gone after washing, but before you place in the dryer or you may set the stain. Repeat if necessary.
Additional hint: If the greasy part of the stain does not seem to be going away you can also try rubbing a small amount of hand dishwashing soap into the fabric where the grease spot is located. This will help remove the grease.
Afterward rinse the stained area well, flushing away both the mayonnaise and grease, and also the dishwashing soap.
Step 1: Scrape up as much of the mayonnaise as possible from the upholstery without spreading the stain further.
Step 2: Place an absorbent, such as cornstarch or baking soda, onto the mayo stain, and let it soak in for approximately 15 minutes.
Step 3: Scrape or vacuum up the absorbent, which has absorbed some of the mayonnaise and oil.
Hint: Depending on the amount of the mayonnaise spilled you may need to repeat this step until no more is absorbed by the baking soda or corn starch for complete mayonnaise stain removal.
Step 4: For the mayonnaise stain still remaining take a clean white cloth and sponge the stain with a dry cleaning solvent.
Hint: First, be sure to test this solvent on an inconspicuous area of the upholstery to make sure it is safe.
Step 5: Next, blot at the stain until the solvent is absorbed.
Step 6: Repeat steps 4-5 until the mayonnaise stains are removed from the upholstery.
If the greasy part of the stain remains you can mix a solution of two cups cool water, one tablespoon dishwashing liquid, and one tablespoon of vinegar. Using this solution, sponge the stain with a clean white cloth, blotting at the solution until the liquid is absorbed, and the stain removed.
Once the stain from the mayonnaise is gone use plain cold water and a new white cloth and sponge the area to remove the cleaning solution, and then blot dry.
Hint: Be sure to get the upholstery only as wet as necessary to remove the mayo stain.
