- Scrape off the excess with the dull side of a table knife.
- Rinse under cold running water.
- Keep the water cold, because hot water sets the egg.
Egg on siding is a protein stain, and fresh egg dissolves in plain water, which is why speed counts. Once it dries it gets harder to lift, and hot water will set it in place, so keep the water cold from the first rinse to the last. A fresh spill usually rinses off with little effort, but an old one may need a long soak, which siding can take with care.
Egg stains on vinyl siding usually lift with the cold rinse, so give that a fair try before anything stronger. If egg yolk stains on siding still show after a soak, a mild dish detergent mixed into a bucket of water is the next step, tested on a hidden spot first. Aluminum siding needs the same patience, so let the soak do the work.

Step by step
Step 1 of 6
Scrape off the excess egg
Use the dull side of a table knife to lift off whatever is sitting on the siding. Work gently from the edges toward the middle, lifting rather than pushing, so the egg doesn't spread.
Step 2 of 6
Rinse the spot with cold water
Run cold water from the garden hose over the area to flush away the loose egg. Use a gentle flow and keep it going until no more egg washes off.
Careful. Hot water cooks the egg and sets it, so keep every rinse cold until the stain is gone.
Step 3 of 6
Test the soap on a hidden spot
Mix the dish detergent into a bucket of water and test it on a small, hidden patch, such as a spot under an eave or the back of a corner. Let the patch dry, then check the finish for dullness or a color change before you clean the visible stain.
Step 4 of 6
Scrub with soapy water and a soft brush
Dip the soft brush in the soapy water and scrub the egg spot in short, gentle strokes, following the direction of the boards. Work one small section at a time so the job stays manageable.
Tip. On fiber cement, a soft cloth does the same job as a brush.
Careful. Don't let the soap dry on the siding; rinse each section before it has a chance to dry.
Step 5 of 6
Rinse the section thoroughly
Rinse the whole section with the garden hose, starting at the top so the runoff carries soap away from the clean siding. Keep rinsing until no soap is left on the surface.
Step 6 of 6
Check the spot once it dries
Look at the spot in daylight after the siding has dried. If a faint shadow remains, repeat the soap-and-scrub step and rinse again. If it is still visible after two rounds, move on to the stubborn-spot notes below.

Best products for egg on siding, roof & exterior
Choose a mild liquid dish detergent and a soft-bristle brush. Skip degreasers and solvent-based cleaners for siding.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on siding, roof & exterior, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
The spot should blend in with the siding around it, with no tacky, shiny or sticky feel. If the area still feels slick or soapy, rinse it again with cold water and let it dry before you judge the result.
What changes for yours
Adjust for your siding, roof & exterior
Vinyl siding
Vinyl responds well to the soap-and-rinse method, and the hose handles most of the rinsing. Keep harsh solvents away from it, including organic-solvent cleaners, undiluted chlorine bleach, liquid grease remover, nail polish remover and furniture polish.
If the spot still looks cloudy after the soap-and-scrub step, let the area dry and check it again before you try anything stronger.
Aluminum siding
Aluminum siding takes the same soft-brush and mild-soap method as the steps above, so follow them as written. What changes is what you keep off the metal, so avoid abrasive scrubbers and scouring pads, which can scratch or dull the finish.
If the spot is slow to lift, be patient with the soap and brush rather than reaching for something stronger. Once it is clean, a final rinse with the garden hose removes any soap that could leave a mark.
Old, dried or set-in stains
Old egg that has dried on the siding is harder to shift, but it is usually still manageable. Start by rewetting the area with cold water and waiting until the crust softens, then scrape it gently with the dull knife before you scrub.
Siding can't be soaked the way fabric can, so the stubborn-spot approach is repeated gentle rounds rather than a long soak. Each round should be one scrape, one soap-and-scrub and one cold rinse, followed by a look in daylight. The heat rule still applies, so keep to cold water even on the stubborn spots.
If the stain is still visible after a few careful rounds, stop scrubbing harder, since that can damage the finish. At that point a professional siding cleaner is the realistic next step.

Do home remedies work on egg on siding, roof & exterior?
Most home remedies for egg stains are fabric tricks or work against this stain, so only one of the common options belongs in the siding steps. The rest are listed below with the reason each one stays out or gets limited.

What makes it worse
Mistakes to avoid
Don't rub the egg into the siding
Rubbing spreads the egg across a larger area and pushes it further into the surface. Blot and scrape gently instead, lifting the egg off rather than working it in.
Don't aim a pressure washer upward at vinyl
Vinyl siding can be damaged by an upward spray, so always aim any spray downward. A garden hose handles fresh egg well, so a pressure washer is rarely needed for this stain.
Don't use harsh tools on fiber cement
Fiber cement siding can't take a high-pressure power washer or a hard metal brush. Keep bleach off it. Keep acid off it as well, and use a soft brush or cloth with mild soap, which is all the job needs.
Don't mix cleaners together
Never mix bleach with ammonia or a detergent containing ammonia, since it forms a toxic gas. If you must use more than one product, rinse the area completely between them.
When to call a professional
If the spot survives a few gentle rounds, or the siding looks dull or uneven after cleaning, a professional siding cleaner is the sensible next step. A pro can judge the finish and choose a product that is safe for it.
Questions
Does egg stain vinyl siding permanently?
Usually not, if you clean it while the egg is still fresh. Scrape off the excess, rinse with cold water, then scrub with mild dish soap and a soft brush. The longer it sits, the harder it is to get out, so act as soon as you spot it.
How long can egg sit on siding before it's too hard to remove?
There is no fixed time limit, but the longer egg stays on the siding, the harder it is to remove. Fresh egg comes off with the steps above, while dried egg needs the repeat rounds in the stubborn-spot notes.
Is yolk harder to remove than egg white?
Yolk has a fatty part as well as protein, so it can leave a greasier mark. Mild dish detergent handles that part, and the same scrape, cold rinse and soap method works for both.
Does siding material change the cleaning method?
The basic method stays the same across vinyl, aluminum and fiber cement. Not much: the cleaning stays the same across vinyl, aluminum and fiber cement, but the brush and what you keep off the surface change.
Is dish soap safe on aluminum siding?
Yes, mild dish detergent in water is fine on aluminum and is the cleaner to use for egg. Use a small amount and rinse it off fully so no residue is left on the metal.
Does egg on siding need a special cleaner?
No. Mild dish detergent in water is enough for most egg stains on siding, and it doesn't need a specialty product. Save stronger cleaners for stains the steps don't remove.
