Best Clay Bar Kits UK (Reviews) of 2021

Best Clay Bar Kit UK

Using a clay bar kit is a nice little way to pre-clean your car paintwork before some polishing and waxing take place, providing you’ve given it a good snow foam blast down first. A jet of water will only do so much for your paintwork and will not remove tough contaminants, making the whole finishing process less smooth and effective on the exterior overall.

A clay bar removes all the little bits of dirt, tar and contaminants that might not be as visible to the eye, but will clearly be visible as you run the bar along the surface of your motors paint. An unwanted build up on your car’s body is natural over time, but this can leave your paint damaged if not treated correctly every now and again. Clay bars are not damaging to your paintwork when used correctly, so take a look at our 5 top car clay bar kits for a more complete detailing finish.

Car Clay Bar Buying Considerations

Kit vs Single Bar

This is more about preference than anything, and may also be determined by what you already have on-hand at home. But generally speaking, a complete kit with the bar and lubricant will give you more value for the money spent. This is especially true of clay bar kits that come with microfibre towels or other accessories that will help you to clean your car and keep it glossy for the foreseeable future. But, if you have the lubricant, towels, and other supplies already, you might just want to buy a new bar and continue to use the products you have on-hand until they run out.

Eco-Friendliness and Lubricant Types

Typically, there is very little need to worry about the bars of these kits containing any harmful ingredients, since they’re made from resins. But, it doesn’t hurt to double-check before use, and also to check the ingredients of the lubricant. Harsh chemicals can harm you just as easily as it can harm the environment.

On the note of the lubricant, you also want to determine what type it is you’ll be using. Some clay bars can work well with plain soapy water or a similar compound, but they usually also won’t provide a high-quality, professional shine like you may be hoping for. The best lubricants will contain ingredients such as wax, and will likely have other synthetic lubricants designed specifically for the job at hand. These ingredients work well together with the clay bar in your kit to provide a glossy, shiny finish.

Colour and Size of the Bar

The size of the bar matters much more than the shape since the bar will need to be molded and ripped apart in some instances for use, particularly in small areas. However, the size helps to determine the value of the bar. The larger the bar, the more use you’ll get out of it, whether it’s cleaning one particular vehicle multiple times or cleaning several. The larger the bar, the more clay you have to work with, and the longer it will take to dirty it all.

Additionally, the colour matters as much as the size. It’s a factor that’s often overlooked, however. The colour of the clay bar can help to determine how much dirt you’ve cleaned off of your vehicle, and will even give you an indication of whether or not you’re claying your car correctly. Darker-colored bars make this difficult, as the dirt from your vehicle will simply blend int. Lighter-colored bars will give you a clear indication of all the dirt you’ve cleaned.

The Final Word

Clay bars are beneficial regardless of whether you look after your car on a regular basis with other products or not. As long as you follow the correct process of giving your car a good soapy washdown first, the clay bar can then work its magic and remove all the nasty particles from your paintwork. Most of our best clay bar kit recommendations above have everything included for a smooth finish, allowing your polishing and waxing process to be more effective.
