5 DIY Car Wash Soap Alternatives Found in Your Home

Car wash

If you’ve got yourself a vehicle, you’ve got to keep it clean. Unless you’re a fan of a muddy, dusty vehicle painted in a lovely shade of bird poop-white. But here’s the thing. Car wash solutions can get expensive, and some are filled with more chemicals than you can count.

Fortunately, there are some other solutions available. You can make your very own car wash solutions at home out of some common household goods.

In this article, we’ll go over some alternatives for store-bought solutions, what cleaners to avoid, and the best commercial soap available—should you choose to use it.

Why Should You Use a DIY Car Soap Solution?

Why not just use a store-bought soap and be done with it? Commercial-grade soaps are convenient and effective. But do you really know what’s inside of them?

Commercial soaps are specifically designed to be tough on dirt and gentle on your car’s paint. And they’re chock full of chemicals. If you like to know what’s inside your soaps, you might want to make your own.

5 Car Wash Soap Alternatives

Now, let’s take a look at some of the best DIY car wash soap solutions you can try.

1. Dish Soap

This is one of the most popular DIY car soaps you’ll see people using. And there’s a good reason: It works.

Dishwashing liquid is often touted to be tough on grease and gentle on your hands, which makes it a perfect candidate for use on your car. A bit of elbow grease and some dishwashing soap can cut through even some of the most caked on mud without damaging your car’s finish.

However, you need to be careful when using this method. Getting overzealous with the soap can leave unsightly residue. We recommend creating a watered-down soap mixture of one part soap to three parts water.

2. Hand Soap

Hand soap’s another good cleaning agent when you’re in a pinch. The soap will clean better than you think. But due to the mild nature of most hand soaps, you’re going to want a higher concentration than dish soap to get the same level of effect.

But that produces an issue. You’re going to end up using near a whole bottle to get the suds you want. At least, you’ll walk away with soft hands scented to your liking.

3. Laundry Detergent

As far as potency and efficiency goes, this is one of the better options available. Laundry detergent is designed to bring out deep-rooted stains while keeping your clothes unmarred. And it can do the same for your car as well. But only if you utilize it properly–especially if you’re using detergent powder.

In order to make the most of this solution, you’re going to need to dilute in water first. However, depending on the brand of detergent, this is easier said than done. If you just dump a scoop of powder into a bucket of water, you’ll find that the powder isn’t just going to dissolve. Even after stirring it around, you may still have grainy bits.

A grainy solution has the possibility of acting like a fine-grit sandpaper on your car’s finish. This can be prevented, though. When mixing your soap, add the detergent powder first. Next pour in some hot water. You’ll need just enough to thoroughly dissolve the soap. Afterward, you can fill up the rest of the bucket and agitate to get suds. Or just use liquid detergent.

4. Baby Shampoo

Those of you with kids may be in luck for this next DIY soap. Baby shampoo works great…in certain circumstances. It’s not the ideal option for washing your whole vehicle. Its super mild nature isn’t really going to cut through accumulated grime.

But remember that bird poop we mentioned earlier? Baby shampoo’s been known to eat right through it.

However, you really need to be careful when using baby shampoo. If you leave the shampoo solution on your car’s paint for too long, it’ll dull the finish. So, if you’re going to go with this method, we recommend washing your car piece-by-piece (from top down) and rinsing as you go.

5. Hair Conditioner

Using a hair conditioner is one of the more interesting options on this list. And that’s because of one of the compounds often found in them. Lanolin found in conditioners is one of the things that really makes your hair smooth and shiny.

And it can help do the same for your car. It’s almost like pre-waxing your car. Lanolin also helps to repel water and protect your paint!

However, this is also one of the more expensive options. A good hair conditioner can have a heavy price tag. And seeing as you’ll need to use a lot of it… It’s probably best to use another solution.

Car Wash Soap Alternatives You Should NOT Use

While the above list is full of tried and true alternatives, there are a few things out there that you should avoid.

  • Household Cleaners: We cannot stress this enough: Do not use household cleaners to wash your car. These are often made of harsh chemicals designed to penetrate deep into tile, grout, and porcelain. And it’s even worse if they’re made with bleach. If you check out our list of viable options, you’ll see we recommend mild natured soaps. These are anything but.
  • Wheel Cleaner: You’ll hear debates about whether wheel cleaner works or not. Just avoid it. It’s specifically designed for use on your car’s wheels. There’s plenty of other options out there to clean the rest of your car.

Which Store Bought Car Wash Soap Should I Use?
