Snowfoam

Not entirely sure how to get in there , could be a wide chisel may go in the plastic slot. Unwind it.
Then finding the exact one.

May do more harm than good... nice suggestion though 👍

That's how you replace the o ring in the genuine karcher domestic lances/adapters. The yellow insert in the end will turn about 90 degrees, either with a wide blade screw driver, coin etc or with a narrow screw-driver into the slot in the side. Then insert can be popped out to reveal the o ring.

Well , the replacement snow foam nozzle arrived , brilliant - works well.
But I see the importance of keeping a car waxed , as I tried it on mother's really dirty Yaris.

Mother isn't fussed about her car, for her it's a tool to get her about - nothing more.

It's maintained but not cleaned , anyway...

Erm... sprayed it with a decent coating, probably 10 to 15mm thick.

Made a right mess 😂 and great fun , and it turned a few neighbours heads.

It probably softened the grime up , but then I was told not to bother ( tbh... it was almost freezing again by that point anyway )

So I quickly jet washed it down, cleared up and packed away.

Good wan, Charlie......I turn off at source and run it to empty hose too. Just remember Karchers are watter cooled, so dinnae run fur too long, ken......? Lol.

Yeah, there are some here that will say don't wet first and some others that I know do (like wot the instructions says on a lot of the snowfoam containers). I wet first too. There's bound to be incoming now.


Just a comment about water spotting. It of course really depends on your water supply, whether it's bore hole or river and/or what rock it's run through (i.e. hard or soft water).

e.g. you can let a car drip dry @ Big Kev's and it will look almost immaculate when dry.

Try doing that in parts of the English Midlands (high dissolved mineral content) and it will look dire, especially on darker paints (but I have been known to be a bit fussy).

(I actually have an ion exchange vessel, which I can put inline before the pressure washer, which I use as a final, short, quick rinse and that helps enormously - well I feel it does. It's also good for cleaning the house windows!).

Foam looks spot on to me.... Any thicker would remove wax any thinner it wouldn’t work very well....

Wetting the car first is something I would never do. We want the foam to dwell on the car not slip away down the drain before it’s done anything. Each to them own.

One of the key points is how good the finish is on individual cars. A well polished and waxed car will benefit massively to the end result.

No one has mentioned whether using hot or warm water. NEVER USE HOT WATER it comes with risks. But warm water and it doesn’t need to be that hot will increase cleaning power and results several fold.

The variations are endless. How good is the car ? How soft is the water or hard ? How good or bad is the product used ?

I have a hot and cold tap at the front of the garage and the water hot and cold is mixed to warm...... That is in my humble the biggest contributing factor.
