That's the price for the 5L, the 1L is $24.95 which seems to me is right in the ballpark for other "premium" washes, and certainly less than some of the high-end ones.

It was my understanding that BH is not producing it in the 5 liter at this time, however it will be available in the 5 liter at some future date. The word around the campfire is even the 1 liter will not be available in the USA for a few months.
I can wait even longer than that. My prediction is PN will quickly become the latest & greatest in the rinseless world and force some others to create similar products. Whether the others knew this was coming or were caught with their pants down is unknown. I assume there are people that are customers of BH were advised that something big would be coming. I saw a notice somewhere on the internet a month or two ago from Labrocosmetica that stated something big was coming from them soon but nothing specific.

Dang, I'm still over here thinking QEW was good enough.. heck even Mr. Clean works well in a pinch. Hopefully it does mean a lot of changes and I can score some more ONR for around $25/gallon.

I saw somewhere Idrosave on sale at a serious discount; my guess would be a new version or a replacement.

Here is a video from Jon that displays the dry mode.

Prewash- a cleaning agent that is applied to all external surfaces, allowed to dwell, it then lifts much of the dirt and then that cleaning agent along with the lifted dirt is rinsed away.
Presoak- either a foaming shampoo or a rinseless wash is sprayed to exterior surfaces and then one engages in a contact wash. The prespray is used as a lubricant for the contact wash and in the case of rinseless washes it encapsulates the surface dirt.

This is my understanding of the differences between the two terms.

Now you used 3 terms, prewash, presoak, and prespray. I don't really see a distinction--one of the distinctions you seem to be making with the "prewash" is it would seem that is for a conventional wash, where "the lifted dirt is rinsed away".

Pre-spray is for lubrication, pre-wash is for meaningful cleaning. I haven’t personally seen a rinseless clean like what BH demonstrated. They do nothing that just pressure washing would do on it’s own.

Yeah, ok, lubrication, but I think all this is splitting hairs (what else is new for a detailing forum). I have found that a "pre-spray" with a pump sprayer doesn't do anything for winter crud, although I would generally do it at 256:1, or sometimes at 128:1. What I have found is useful is to do what Optimus has been doing with his Ego sprayer, is to spray rinsless with my old Harbor Freight airless paint sprayer, popularized by that guy Scott from YouTube, or more recently with a garden sprayer that I have mentioned here in other threads.

In that case you can sort of blast the grit off the car with spray pressure, without using much liquid, before you contact wash...call that pre-spray, pre-rinse, pre-wash, pre-soak, pre-lube, pre-mature, whatever. I think we are making this all too complicated (what else is new for a forum), but I have come to the conclusion that pre-something is best practice vs. going straight to the paint with your rinseless media.

Found this as far as dilution ratios go on a non bh website.

Yow, that's a lot of warnings at the bottom. As Yakky alluded to, I don't think anyone ever worries about QEW (which they don't make anymore...do they?) or ONR drying on your paint.

Yes i use presoak & prespray interchangeably. Same thing. Which is either spraying rinseless on before contact wash or foaming neutral shampoo before a contact wash but most times i do a foaming prewash with a product like Primus before the shampoo wash. They really are different. The prewash is for cleaning. The presoak is more for lubrication but also for cleaning. Most rinseless washes make poor prewashes. Probably benefit more from the pressure washer than the rinseless.

These are how I see the various terms.

Pre-wash - Soap/detergent (not a rinse-less/normal soap ) that lifts/cleans in a touchless manner and is rinsed off with water (pressure or otherwise) before a normal wash/rinseless.

Pre-soak/pre-soray - Wash/rinseless that is applied to the paint immediately before a contact wash. Can be combined with a pre-wash for extra lubrication/safety etc. usually matches the wash detergent/rinseless being used. Also used on a zero rinse wash before a rinseless wash.

Influencer method - Pre wash with a high PH shampoo, rinse, pre-wash with an acidic shampoo, rinse, presoak with rinseless, rinseless wash, foam with PH7 shampoo, rinse, pre-spray with rinseless, clay, pre-soak with iron remover, clay again, rinse, waterspot remover, rinse, bead, polish with mostly oil, rinseless wipe, ceramic coat, coating fails, reapply water spot remover.

Pretty accurate! You should continue with their entire routine. My favorite is when they evaluate how a coating is doing after they top it with a spray wax/sealant.

I remember when someone here or at Autopia told us he got a year out of some sealant, which we thought was an awful long time for that product, and that it was still beading like crazy, so we asked what his maintenance regimen was, and he told us he washed every week and then used a spray wax...every week. So I asked if maybe it was the spray wax every week that was giving him the beading, and he said "no, it's the sealant".

Top up culture, it’s the reason any product has a positive review when it comes to durability. “I only topped it up twice in 6 months” is enough for a decent product to last on its own, let alone a coating.

$25.00 for a liter is actually pretty good IMO!

I'd still like to see how it does, breakdown wise, to Preludio alkaline or acidic because that's a hidden gem that doesn't seem to get mentioned by what, the 20 of left here, LOL

It's Parks car care that has Idrosave in the 250ml bottle for 43% off...and they are out of stock on the 1L and 5L, that's what made me think this...they are also sold out on the Preludio bundle that includes Idrosave, but they have Preludio in stock. However, no one else seems to have Idrosave on sale so maybe Parks just doesn't want to sell it anymore.

Well seeing as nobody here has this product in hand and now that I've had some time to think about it. If one has to get out a pressure washer or even a hose to rinse this product off in either dry mode or lift mode then one might as well use a good foaming prewash such as Touchless or Primus. Then if you already got your stuff out might not be much more to do a foaming contact wash with a soap.
After all it's a rinseless wash. A shampoo wash is always a safer/cleaner/better wash in my opinion. Not knocking the product as it may very well be the best cleaning rinseless wash to this point, but it's still a rinseless.

Looks like people here in the US are getting their hands on it, Fine Detailing has a YouTube on it.

You can buy it direct from bilt hamber. Just prepare to pucker up. It’s $130 for me, not including potential additional duty charges.

$130.00 for a liter bottle? Sorry but thats NFW. For that price it should be a 5 gallon can of rinseless.

I believe that's to have it shipped from England. As I said earlier in the thread, the price Carzilla had for a liter was $25 USD

Here is the Bilt-Hamber how-to-use guide for Phat Neut: https://bilthamber.com/wp-content/uploads/2026/05/Phat-Neut-how-to-use-guide.pdf

If I can say so, I think detailing has jumped the shark. This is the most complicated instructions for washing a car I've ever seen.

I think it's Yakky and others that have complained about the YouTube foam/rinse/foam/rinse/foam/rinse 14-bucket method. If I was new to this and decided "maybe I'd like to wash my own car" and I read that how-to guide, I'd be going straight to the tunnel wash.

When I came to detailing forums 22 years ago, I found out that I should ditch my car wash sponge and get a sheepskin mitt, add a rinse bucket with a grit guard, and dump my cotton terry drying towels for a waffle-weave microfiber.

Today it would seem a newbie needs a pressure washer, a foam cannon, a pump up sprayer, and the ability to discern whether their dirt level is sufficient for Dry-On® mode or if they can only use Lift-Mode®. Kind of takes all the fun out of it.

Here's the Phat Neut "quick reference table": https://bilthamber.com/wp-content/uploads/2026/05/Phat-Neut-Quick-Ref-Table.pdf

The normal rinseless wash dilution is 250:1, but there is an "extra lubrication" rinseless dilution at 200:1...which states "do not allow to dry".

In the Fine Detailing video he did let it dry on his test panel, and it didn't seem to damage anything, I think that was at the Dry-On® dilution.
