Natural waxes only come in paste form, and although they take extra effort to use, they produce the best results. The catch? They tend to be more expensive, and also only last for six to eight weeks. As you might have guessed, car wax contains natural wax. Don’t be fooled by car waxes that don’t contain any natural wax, as these are technically called paint sealants, no matter what the manufacturer says. Typically, a hard car wax has around 30-40% carnauba wax.Naturally, the higher the natural wax count, the better protection it will offer. However, don’t be fooled by manufacturers suggesting products feature 100% carnauba. Carnauba is hard, so you’d never be able to use the product if it was 100%. Instead, what they mean is that of the wax being used, it’s 100% natural carnauba wax. The rest of the product is made up of various oils and solvents.

Wash waxes will save you time - but that doesn’t mean there’s no effort involved in applying them. So you want to make sure all that elbow grease pays off with a layer of protection that lasts. In our test, we applied each product to a section of car bonnet and we monitored how water beaded across it over four wet weeks and three dry weeks. Also, we factored-in the cost of each of them, along with ease of use and any extra items that were included, such as cloths.
