‘Can I use dishwashing liquid to wash my car?’ [Newbie Guide]

Updated Jul 29, 2022

You might save on costs, but you won’t be doing your car any favors. 

Rising oil prices have a domino effect on how much everything else costs, and this is especially true where automotive-related products are concerned. Practically anything that has something to do with your car is bound to be more expensive, from the fuel it runs on to the parts it uses.    

Washing the car is a satisfying chore for many car owners

One car item that motorists rely on to maintain their rides is the car wash shampoo. After all, a clean car beats an expensive one any day. Of course, an easy way to keep the car clean is to bring it to the car wash, but many car owners prefer to take the hands-on approach, investing time and effort to pamper the car themselves. 

However, sometimes a car owner’s desire to save on costs can have disastrous results. Washing a car in the comfort of one’s garage is one thing, but then someone might go further and consider substituting the regular car wash brand with dishwashing liquid, thinking that it will have the same effect since both are used for cleaning. 

We’ve got news for you: they’re not the same, and it’s not just about cutting costs. 

Don't be tempted to use dishwashing liquid in cleaning your car

Aside from washing dirt and grime off the vehicle’s exterior, a car wash shampoo also leaves a gloss that’s good for bringing out the shine on your ride’s metal exterior. It’s one of the things that shouldn’t be missing on the list of essential car care items. 

Replacing your car’s shampoo with dishwashing liquid achieves the exact opposite. The latter is formulated to remove oil from kitchenware, which is why it needs to have an abrasive quality. If you use dishwashing liquid to wash your car, those abrasive additives and degreasers can strip away the protective topcoat on the car’s paint, leaving it vulnerable to corrosion.

And that’s not even mentioning the dull finish that will result, compromising your car’s aesthetics. Unless you prefer the matte look, in which case it would be better to use a foil wrap instead.
