The biggest benefit of car wash shampoo is that it will clean your car without stripping away any wax or paint sealant that may be underneath that thick layer of dirt you’re finally fed up with. Household soaps and detergents tend to be harsher than car wash shampoo and break down waxes and sealants.

Car wash shampoo is designed to specifically break down the bond that dirt and road grime have on your car or truck but not be so harsh that it will break down the wax or paint sealant that is protecting your finish. The primary way this is achieved is by formulating the shampoo to be ph neutral.
Another good reason to use car shampoo is that it’s pretty inexpensive when compared to hair shampoo, laundry detergent, or dish detergent. You can pick up a gallon of car wash shampoo that will last an extremely long time for 25 bucks or so depending on the brand. My wife’s shampoo comes in a tiny bottle and costs more. It’s probably close to the price of gold pound for pound.
Do yourself a favor and go ahead and buy some car wash shampoo now so you’ll have it on hand the next time you need to wash your car. You’ll be glad you did.
Sure, but it’s going to be harsh on your finish and not help with the longevity of your wax or paint sealant. Like most household soaps, it is going to be harsher than car shampoo because it’s not designed to wash an item with a coating. For instance, dish detergent is designed to break down grease and food particles. It’s great for cleaning oil off ducklings and probably axle grease off your lower control arms but it’s not ideal for your finish.
A better car wash soap alternative is something that is going to be a little more gentle. An excellent choice is hair shampoo. I honestly have to say I’m not very discriminating with my shampoo choices. Even though I may not buy the highest quality shampoos they will be more gentle than dish detergents or laundry detergents.
My wife is much more critical when choosing a shampoo. The shampoo that she uses is likely far more gentle than the cheap brand I picked. If you live with someone that is more particular about their hair care products and you think you’d survive stealing a bit. The best choice for washing your car is a premium hair shampoo if you don’t have a quality car wash shampoo. My wife would be livid if she found out that I wasted her precious hair product. But your situation may be more conducive to you surviving the shampoo theft unscathed.
Some will suggest baby shampoo as an ideal option. Interestingly baby shampoo is going to be slightly more acidic and therefore harsher on wax and paint sealants protecting your clear coat. The reason why baby shampoo is ironically more acidic is that it is trying to match the natural physiological ph level of baby. This will prevent irritation but is actually harsher than the lower ph of shampoo.
Some people wonder if laundry detergent is a good choice for washing their car. Laundry detergents usually have strong degreasers and other harsher chemicals to help break down dirt stains and grime embedded deep within fabrics. This are going to more harsh than using a proper car shampoo.
If you’re considering using laundry detergent, it isn’t likely going to be your best choice but it won’t be the end of the world either.
