Now, i'm a simple man but consider myself decently educated. I'll also pre-answer what all of you will say "Oi, Davie - you're over thinking this...."

I'll preface this by stating that i think it has to be this complicated as the flow of water discharged over the period of time it takes to empty the bottle is important (more water, more product, less water, less product) but i guess the question i *really* have is that we simply have to do this once and providing we don't change pressure washers or use larger snow foam bottles then we don't have to do this consistently.

Maybe i'm not that educated now i think about it, but i'll take one for the team...

I even asked chat GPT to help me out and said that it takes 3 litres of pressure water to empty the 1 litre bottle, it says if that's the case and i've added 40ml (4%) then the effective dilution is actually 1%, and this makes sense to match the total amount of water delivered. So, to achieve an *effective* 4% dilution over 4 litres of water being delivered (including the one litre bottle) then i must at 160ml to achieve 4%.

Can someone that can count please put me out of my misery? Surely if i simply add 40ml to a one litre bottle then i get a good PIR? I haven't even thought about what the impact of adjusting the snow foam lance to min / max might do. At this point i'm just going to burn a bottle of product and see what happens....

So, when i commited to buying some of the mega rated Touchless snow foam i thought i would look up what i need for my 1 litre snow foam bottle.

Bilt hamber doesn't use simplicity... oh no.... they use PIR (Panel Impact Ratio) ffs.

https://bilthamber.com/product/touch-less/ - click on "how to use" and these maniacs will have you fill a litre of water into the bottle then discharge into a bucket until the bottle is empty. Then multiply this by your required dilution (0.04 for 4% for heavily dirty cars, 0.02 for 2% for a maintenance wash and so on).

You take that total amount and then bung the value calculated into the bottle.

Why, for all that is holy can't they simply say for 1 litre of water simply add 40ml to the bottle for 4% , 20ml for 2% and be done with it?? Why do they need to try and explain this like scientists (granted that's what they are)....

Sake!



Even ChatGPT is dumbing it down...

You want the solution in the bucket to be at 4% - that’s the concentration you want it to be coming out of the nozzle. If you start with 4% in the pressure washer reservoir (40 mL in 1 L) then it will be too dilute on the car; using your example of 3 L in the bucket as the total volume that comes out of the washer in the time it takes to empty the reservoir (which seems far too small a volume anyway - I would expect more) then the “PIR” is 40 mL in 3000 = 1.3 %
And yes, I agree that the way BH describe the calculation is confusing.

Using a karcher k4 and autoglym snow foam blaster thing, I put 300 mil of touchless into the bottle & topped up with warm water - 700 mil ish.

This is inline with bh’s recommendations.

Cheers, i have a K4 and the only number i'm not sure about is flow from the washer. If you're putting 300ml in ant the total amount of liquid delivered is 4000ml then that must be approaching 9-10% dilution. Will do the job but wonder if theres room to reduce waste.

It is because of the variability between machines of how much detergent is sucked out of the bottle per litre of water flowing through the machine.
Putting a litre in the bottle then measuring how much water it takes to empty it gives you the 'machine dilution ratio', and you need to take this into account to mix the liquid to put in the bottle. A machine that empties the bottle twice as quickly, (ie with half the amount of water through the machine) needs half the amount of concentrate in the mix in the bottle to give the correct dilution at the nozzle.

It’s not set in stone, have a play with the ratios until you get the performance/ product cost ratio to your liking.

Ive not checked my ratios which i have written on my garage wall but im sure its more like 40 ml of product to 1L not 400ml.

It’ll depend on your equipment but mine was about 400ml. It seems a lot but it worked really well.

That would be correct if using a hand held pressure sprayer.

I must be thinking of Touch on then which im sure is around 30 ml. 400ml of product does seem like a lot but it depends how many washes it lasts i suppose.

I did the litre of water in the spray bottle, set the rate/release valve to the normal setting and run it into a bucket. Then did the maths …. Then they reformulated it….

Touch On is around 30ml to a litre bottle, it’s much lower than Touch Less.

I normally put around 250ml of snow foam or whatever in the bottle

Don't think but the most ott person goes by the brands that say to do it by a certain % of flow rate or whatever

Is this the new touchless or old touchless formulation you're referring to?

The new one is much more concentrated and has a max PIR of 2% for heavy soiling, with 0.5-1% being enough for maintenance washes.

If you use 4% PIR you might damage whatever wax/coating you have on the paint.

The new formula, should have stated that actually on the post and was part of the reason for the post.

I am looking to trip the car back from whatever is on there though - previous owner and me have attempted all sorts of things to deal with the swirls. I'm looking to get it back to bare swirls, but not bare paint / primer biggrin. Then from there i'll combat some swirls as best i can or just get some layers on for the winter and attack the swirls in the spring.

I apply it with a pump-action sprayer bottle. The foaming action adds no cleaning value, and it avoids all the calculation faff as you just add the percentage of the capacity of the bottle.

IIRC The Forensic Detailing YouTube channel has done a piece on PIR.

I just watched that actually and does a decent job.

Yeah, I thing the foam is just there to provide extended hang time that in theory should lift more crud.

I’ve found the best thing to do is pour a small amount in the bottle and worry no more.
