Car Shampoo Buying Guide
Car shampoo is an essential product for washing your car and it’s available in several forms. It’s highly advised that you avoid using household solutions for washing your car as they can be tough on the paintwork. They can also strip any car waxes that have been previously applied to the car too.
Depending upon whether you use a pre-wash technique, you may also require two different shampoos for use with a pressure washer and then with a car wash bucket.
To help you make an informed buying decision, we have produced the below guide regarding car shampoos.
pH Balanced Formula
The car shampoo that you use will need to maintain a pH balance that’s similar to water. This is required because it prevents the shampoo stripping any wax that you’ve applied previously. Higher alkalinity to the formula does assist with breaking up dirt and can be useful in certain situations but it shouldn’t be used on a regular basis.
Amount of Suds
Car shampoos that produce plenty of thick suds will be more effective at removing dirt particles without scratching the paintwork. However, some people may prefer the lack of suds because it provides a sheeting effect that lets water run off the paintwork. Therefore, depending upon how dirty your car is will determine the amount of suds that’s best to clean it.
Inclusion of Wax
Some formulas may include carnauba wax and other special ingredients to make them standout from the hundreds of shampoos available. Although it’s not strictly necessary, it’s very beneficial for those that occasionally wash their car. However, if you intend on polishing or waxing the car straight after washing it, it isn’t really worth paying the extra for a shampoo that includes wax.
Water Spot and Streak Resistant
After washing your car, there is nothing worse than seeing water spots or steaks upon the paintwork. They are made noticeable under direct sunlight or lighting and can make the car look worse than it did before it was cleaned. Using a quick drying formula will prevent both of these issues and make washing your car slightly easier.
Other Desirable Features
Many brands will state that their car wash shampoo formula is 100% biodegradable. Although this may not benefit your car, it’s environmentally friendly because once the soap is removed from the car, it goes down the drain.
A benefit for the person washing the car is the scent from the shampoo. There is an array of fragrances available and it makes using the shampoo slightly more enjoyable and you can often smell it from the car hours after washing it.
Conditioning is often included in the formula of some shampoos. They are designed to enhance the colour of your paintwork as well as making it more slippery, which improves water beading.
Most brands also offer their shampoos in a range of different bottles sizes. If you want the best value for money, you will want to purchase the larger capacity bottles. It’s worth noting that some formulas are concentrated, which means you may be getting more shampoo but just in a smaller bottle.
Best Tips For Washing Cars
The simple task of washing your car is something many people get wrong on a regular basis. Using an improper technique can increase the chances of swirl marks, scratches and other defects in the paintwork.
We highly recommend that you adopt the “Two Bucket Method” for washing your car. Although you’ll need to purchase an extra bucket, it will ensure that the wash mitt that you are using remains clean and free of any dirt.
You should also chuck away any sponges and invest into a proper wash mitt that captures dirt. If you use a sponge, the dirt becomes trapped between the paintwork and the sponge, which may transfer onto the paintwork and cause scratches.
In terms of your technique, we recommend that you start with the wheels. Begin by using a wheel cleaner and allowing the formula to get to work. You can then spray away the residue and clean any leftover dirt with a wash mitt dedicated for your wheels.
Once the wheels are completed, you can fill up two wash buckets with warm water and the car shampoo. Starting from the top, begin to wipe down each panel and regularly dunk the wash mitt into the bucket using the Two Bucket Method.
Once every panel is cleaned, begin to dry the car using a microfiber drying towel. It’s always recommended that you wash your car in the shade and not in direct sunlight. This will give your more time to properly dry the car and also reduce the chances of water spots appearing.
In order to safely wash your car and avoid stripping any wax from the paintwork, you will need a quality car shampoo. There are hundreds to choose from but the above recommendations are suited to a range of budgets and car washing methods. It may be tempting to use household cleaning products but you can cause damage to your paintwork. Considering most car wash shampoos are fairly cheap, it’s strongly advised to buy the best you can afford.
