Well, I decided to try the "rinseless" to make my life a little easier. As a test product, I chose the Absolute.

In the end, it won me over, but with some observations:

- Most people recommend spraying the car (with the same mixture, that is 256:1) with a sprayer before washing, keep this in mind as well.

- I would only use it straight (spray-wash-dry) for light dirt (in which case the washing is extremely quick!), not after rain, etc.

- The above does not mean that it cannot be useful in other cases, where I have settled on a hybrid wash, that is:

1. Spray with a foam cannon with active foam and a quick rinse (without using hands, that is). This stage takes 5 minutes and removes all the "heavy" dirt.
2. Quick spray with a rinseless sprayer (2 minutes).
3. Hand wash.
4. Drying.

Compared to a classic wash, you still save a lot of time as you do not do the final rinse, which takes quite a bit of time because you have to ensure that all the soaps are rinsed off very well.

Optionally, between steps 1 and 2, you can also do a little by hand on the wheels with the active foam you applied, because the grime there will be hard to remove only with foam without contact.

- Although I liked the Absolute, my next purchase will probably be the DIY in a gallon package, which is currently just over €14 per liter. About the same price for Koch Chemie, which, however, does not have the best reviews so far.

- For washing, I tried the method with multiple cloths (which uses less product and is safer), but it is a hassle, I can't handle it. So I got a "rinseless" sponge (the one with the grooves) which is very quick. I got a Chinese one because I didn't want to spend almost €40 (!!!) that the branded ones ask for. It seems good so far, we'll see (basically to make sure it doesn't damage the paint, I mean, in terms of use and durability, it's just fine).

Excellent product, it does exactly what it promises.

It is better not to use it on a car that has gone off-road and is covered in mud.

I live in an apartment building without a garage, so I don't have access to water and electricity, and this particular cleaner has saved me.

This specific soap, as its name suggests, is for rinseless cleaning. However, this does not mean that you cannot use a pressure washer or hose for pre-rinsing.

In addition to exterior washing, it can be used as an interior/glass cleaner, clay lubricant, and quick detailer (for light cleaning, such as bird droppings). The ratios are indicated on the back of the bottle.

The ratio for washing is 256:1, meaning 256 parts water to 1 part of the liquid. The equivalent is 4ml per 1 liter.

Personally, I use 1 bucket with 8 liters of water and add 32ml of the soap.

The process I use is as follows:
-Spraying the car with a pressure sprayer (I put the sprayer inside the bucket with the mixture to take the water from there so that I don't have to adjust the ratios again) - You can also use a regular sprayer.
-We wait for 1-2 minutes for any dirt on the car's surface to loosen.
-Washing the car with a wash mitt (you can use multiple microfiber towels if you prefer, but you will have more towels to wash in the end. There is also a specific sponge that you can use, such as the Ultra Black Sponge / Legacy Sponge - I plan to buy one at some point).
-Drying the car or the panel I have washed with the help of a quick detailer for faster drying (drying aid).
-Wheels / tires.

Tips: For better homogenization of the liquid, use warm to hot water. I pour the liquid into a 500ml bottle with warm water and then pour it into the bucket with the rest of the water.

If there is sun/heat, then we do one panel at a time.
