Disappointed with Bilt Hamber Auto Foam

Hi guys,

Having read rave reviews on BHAF, I bought some with high hopes of its cleaning abilities.

I used the product for the first time yesterday and have to say I was quite disapointed with it’s performance.

I’m either doing something wrong or my expectation levels are completely unrealistic. I don’t believe it’s the later after seeing the results as it really didn’t look like much if any of the dirt had shifted.

This was my process:

- mix to 4% PIR, applied through pump sprayer, to a dry car
- applied too fine to begin with, dried out very quickly. Adjusted nozzle and applied enough to produce a run off then moved to next panel.
- intended to leave for 10 minutes but appeared the product was drying out, left on for around 8 minutes.
- car hosed off with normal hose spray head
- car left to dry to see the effectiveness of the BHAF to see how much dirt had been removed.

Car dried and it looked like very little dirt had been removed.

The only thing I can think is wrong with the process above is that a PW wasn’t used to rinse the product off. The spray produced by the spray gun while not comparable to a PW is maybe not strong enough to blast the dirt away.

Am I relying too much on the product here? Is the PW necessary to get the results everyone seems to get?

If this is the case, is it really the pressure washer that’s moving the dirt and not necessarily the BHAF? After my results yesterday I would have yielded a better pre wash using just a pressure washer alone rather than the pump spray BHAF and hose off afterwards.

BHAF doesn't foam up as well as other foams which can appear disconcerting, but it's the cleaning agents that are key to how well it performs. PW rinse will help immensely.

Thanks for the reply. Was aware of the lack of foaming, especially through a pump sprayer, product was brought on the merit of its cleaning abilities.

Problem is, I didnít get much cleaning.

Maybe the BHAF is softening the dirt in readiness to be blasted away and my garden hose nozzle just wasnít strong enough to move the dirt off the body of the car.

Would be interested in seeing a PWashed panel vs an autofoamed then pw rinsed panel. Iím sure the later will be better, but by how much?

I have only ever used a power washer to remove the foam. I have never considered using just a hose (not saying it’s wrong). I have never been anything over than amazed at how good it works with the power washer. Also, I know for a fact that many times I have used it at less than the recommended 4% PIR and have still had excellent cleaning results. I have applied it with both a snow foam gun and a pump dispenser but always use a power washer to remove it.
You will not get better results just power washing the dirt off, the BH Autofoam softens the dirt and grime which makes it easier to blast off with the power washer.

I think the lack of PW rinse could be my problem here. I was using the BHAF prior to using ONR for the first time - to add another level of security.

Iím trying avoid getting all the kit out and keeping my wash to the minimum time necessary.

Looks like you only get the result so with BHAF (probably any foam for that matter) if youíre PWashing as your rinse.

Ths is exactly what is happening. The surfactants in AF soften the dirt but you will still need a high pressure rinse to lift and remove the dirt. Also I think you're leaving the product on a tad too long, 8-10 minutes and the product will start to dry on the panel, particularly when used as a spray.

Iím a big fan of Bilt Hamber products. In the past Iíve used auto foam and agree it doesnít foam much. I became a little disappointed with its performance and switched to Koch-Chemie green star which works incredibly well from a pump spray. IMHO I think it out performs Auto foam as a prewash.

I don't think it's as good as everyone says either but that's why we all have opinions.

I use Koch GS in a pump sprayer or AutoGlanz Spritzer in a lance. Perfect!

I use BHAF professionally for years....and nothing comes close to its pure cleaning ability and I've tested the majority of the big name foams....I always use it through my MTM foam cannon via one of my K10 machines....

I used same process including hose pipe and it lifts all the dirt and can see it running off, i do get drying out if the spray is too light though,

I currently have fusso on the car which may make a difference,
