Am I Overthinking Car Wash Shampoo for Home Use?

Hi everyone,

I’m looking for some advice on washing cars at home and wanted to hear your experiences.

Recently, I did some research (with the help of ChatGPT) and learned that using a pH-neutral car shampoo is recommended to maintain the original paint finish and shine, instead of using regular household shampoos or detergents. One product that was suggested is Meguiar’s Gold Class Car Wash.

However, when I checked the price, a 64oz bottle costs around LKR 9,000, which feels quite expensive. I’m wondering if it’s really worth the investment for regular home use.

I also found that many standard car wash centers don’t use pH-neutral shampoos—only premium detailing centers seem to use them. So now I’m a bit confused about what actually makes a noticeable difference in the long run.

For context, I’ve been learning proper washing techniques like the two-bucket method and other best practices to avoid scratches and swirl marks.

So I’d really appreciate your opinions:

• Do you use pH-neutral shampoo at home?
• Is Meguiar’s Gold Class worth the price, or are there better alternatives?
• Does it make a significant difference compared to regular car wash products?

Thanks in advance for your insights!
