You can soak the soap and water mixture into a towel as you go, or prepare it in a spray bottle beforehand for ease of application. Watch out for industrial cleaners. They can be extremely harsh on paint, and if you’re not careful you could make the problem worse.
While softer surfaces are less likely to damage your paint, it will take longer for them to work on the stain, increasing the total time of the process.
A chamois or microfiber towel works best for drying as it absorbs and holds moisture.
Soak the sandpaper in water for a few hours (or overnight) to slightly soften the grit. Otherwise, the friction of the sandpaper is more likely to damage your car. Cutting the sandpaper will create a smaller sanding surface, making you less likely to accidentally scrape other areas of paint. Alternatively, a Mr. Clean Magic Eraser might do the trick. Its dense plastic surface works much like a fine, high-grit sandpaper, and it can be purchased in most supermarkets and convenience stores.
You can optionally apply a polish coat at this point. Use a pure polish on the buffed area to remove any unsightly swirl marks. If the egg damage is still not gone, you may have to do an area respray (spot-blending). If you’re not familiar with how to use a machine polisher or don’t have access to one, take your car to a garage to be polished once you’ve removed the stain.
Caution: Brake cleaner is a toxic, corrosive and potentially flammable solution. Exercise care when using brake cleaner fluid at home. If applied improperly or left on too long, it could cause considerable damage to your car’s paint. [6] X Research source
Paper towels are optimal when working with brake fluid as they can be disposed of. Avoid using a towel that you might reuse as the brake fluid is toxic and mildly corrosive.
If you want your paint to look best, the mechanics at your car’s dealership can touch up your car professionally for a small fee.
Wash & Wax cleaners work essentially the same way that brake cleaner fluid does, but are intended for use on the vehicle’s exterior and are safer for most common uses. There is no guarantee that a Wash & Wax will work for its applied purpose here. They can be an effective cleaner for many types of dirt and stains that build up on vehicles, but you’ll be using at your own risk.
Nylon scrapers are cheap and safe. It’s better to spring for one than to use a harder scraper with unexpected results.
Use a microfiber cloth to buff the spot. In all, this should only take about 20 minutes, with minimal muscle.
