Bilt Hamber Auto Foam Review - Cost-Effective Cleaning Without a Compromise on Performance

Updated: Mar 31

Snow foaming is a vital part of the detailing process, particularly when starting with a filthy car. Every detailer and car enthusiast has a go-to snow foam, and Bilt Hamber makes some of the best in the business.

Following on from our look at the newer Touch-Less Snow Foam, we’re going to take a look at Bilt Hamber Auto Foam that has set the benchmark for so many years with its cost-effective and efficient cleaning performance.

Why Use Bilt Hamber Auto Foam?

Firstly, this is a Bilt Hamber product, which guarantees quality. They simply don’t make sub-par products. If they turn their hand to developing a product, be it a snow foam or a car wax, they are usually right up there with the best in the market.

What we like the most about the affordability of this snow foam is, with a five-litre bottle costing just £18.95, you can make that product last a long time since you don’t need to use much for each wash. In fact, it probably delivers the best clean within this price bracket. It doesn’t lather as nicely as some of the other snow foams out there, but it works really well on heavily soiled cars.

This particular snow foam is built with functionality in mind rather than aesthetics. So while it might not look the prettiest, it always gets the job done. It’s non-caustic, too, minimising the chances of swirl marks and any damage to the skin should you come into contact with it.

Lastly, this solution is extra flexible, working with all types of equipment, including pressure washers and foam lances.

How to Use Bilt Hamber Auto Foam?

The procedure for Auto Foam is pretty straightforward and follows that of many other snow foam products. As usual, make sure the car has cooled down after driving and try to avoid parking it in direct sunlight, so you have enough time to remove the product before it dries.

The PIR (panel impact ratio) or final dilution ratio (FDR) depends upon how dirty your vehicle is. A 3% PIR ratio is a good rule of thumb for Auto Foam, or you can go for a 4% ratio if there is a lot of dirt and grime on the paintwork.

Once made up to the mentioned ratio, we recommend applying the snow foam with a foam cannon or hand foam sprayer (IK Foam Sprayers are a great choice, and we stock them in the MD Detailing online store).

Leave for 5-10 minutes (although the longer, the better for it to do its stuff). Just be sure not to let it dry. Then, thoroughly rinse before you wash.

It's an excellent idea to apply Bilt Hamber Surfex HD before applying the Auto Foam on top. Surfex HD is designed to fend off the grease-based soiling from any part of the car, even from rims and tires. The use of the degreaser makes the task of Auto foam much easier, and you get better results in the end as a result of using these products in tandem.

Bilt Hamber Auto Foam Verdict

Overall, Bilt Hamber Auto Foam is an excellent snow foam that does its job well at an affordable price point. Though it doesn’t boast the same lather as other more expensive snow foams, it does the job of removing dirt and grime every bit as well, paving the way for your car shampoo to finish the job.

It’s a best-seller at MD Detailing for a reason. We stock 5-litre bottles of Auto Foam for just £18.95, and it’s a great idea, as mentioned, to also stock up on Bilt Hamber Surfex HD to get the ultimate deep clean finish. We offer the two products as a double pack for just £34.58.
