The water for watering at Tsukuba Circuit was well water: Ion deposit measures

I wrote a while ago that my beloved black carrera (991.2 carrera) got very dirty after doing a steady circle at Tsukuba Circuit, and that dirt couldn't be removed at all by a normal car wash. ..

Since then, I've asked and investigated various things, so I'd like to write them down.

However, the content I will write this time is about September to October last year (I haven't been able to write it for a long time).

So, a little while ago, this time's content is a continuation of this story:

① Drift practice of Porsche 911 at an event hosted by Porsche Club Utsunomiya
② Bring back the Porsche 911 full of ion deposits that seems to have been made by well water

At this time, we would like to hear from the people who have done steady circle and open space training many times in the past, the Porsche Center people, the three coating companies, and the staff of Tsukuba Circuit. I did.

Thank you to everyone who talked to us.

I'm sorry that the black carrera got dirty and I was in a hurry too much, and at this time I was really in a hurry and heard various things ^ ^

I am really grateful to many people for their kindness and help.

What was the dirt this time

The first thing I wanted to know was, after all, "What is the dirt that does not come off at all? What is the cause?"

In conclusion, the dirt on the car this time is probably the so-called "ion deposit". Of course, this is just a guess.

However, when looking at the condition of the car and listening to the story, he said, "Maybe it's an ion deposit."

Still, it's true that every coating shop said, "I've never seen anything so terrible."

What's this dirt! It doesn't come off at all just by washing the car normally, and it remains in this dirty state! !!

What is an ion deposit?

Ion deposits are whitish stains that remain on the body when the water dries and the water droplets (impurities mixed in) remain on the body.

As a result of various investigations, it was found that this ion deposit is especially easy to get when using "well water", so this time I decided to check the water that my car had spilled.

The water that my black carrera was exposed to this time was the water sprinkled by a sprinkler at the Gymkhana field on the Tsukuba circuit.

The water sprinkled at Tsukuba Circuit is well water

Here, a surprising fact turns out.

What. The water sprinkled at Tsukuba Circuit was well water! Yeah? I'm not so surprised (laughs).

The water pumped up for the sprinkler is well water, and the water coming out of the faucets in the Gymkhana field is also well water except for the water in the administration building and the toilet (inside the administration building and the toilet). The water in the faucet is purified water).

However, it is also questionable here.

Because, in the past, I was doing the same steady circle with the water drawn from the same Tsukuba Circuit's water pumping place (the sprinkler is also the same yellow whale), but in the past so much The dirt was never removed.

Until now, even if the car was washed after a few days of being bathed in sprinkled water (well water), it had returned to a shiny state just by washing it with water.

I did the same on sunny and hot days, but until now it wasn't a problem.

Then why only this time?

This "why only this time?" Is really mysterious, and this is the most questionable point, but it is said that the well water for watering at Tsukuba Circuit is disinfected at the same rate (with chemicals) throughout the year. By the way, I couldn't think that there was more chlorine than usual because there was less disinfection only this time.

Only one point.

It was said that the person who refilled the sprinkler with water at the event I participated in this time said, "This time, the speed at which the water was pumped up was much faster than usual."

Oh. Is there any difference? !!

Hmmm, but no, what's the difference (laughs).

Well, no, but I'm sure well water ... Yes, maybe something has changed in the underground water vein (forced)! !!

I came here and the groundwater level fluctuation theory of Tsukuba Circuit broke out ... Only in me (laughs).

Is there a change in water quality due to fluctuations in the groundwater level? What? So, even with the same proportion of disinfection with chemicals as usual, did the water quality differ? What?

Yeah, that completely unreliable content, almost a lie 100%, so please go through (laughs).

I couldn't come to a conclusion, but I read about the groundwater veins and groundwater in the Tsukuba area (laughs)!

I was in a panic state when I couldn't get rid of the dirt on the black carrera and it would happen again every time in the future. Was ^^

How was the situation with the other cars

After that, how was the cars of everyone who participated together on this day ... I asked them various stories, but it seems that there were many people who had the same dirt on them. am.

It seems that there were many ... because they were all professionals who were accustomed to the steady circle and used the car that way ... "I don't care if it gets dirty in the first place?" (Lol).

Even if it is not so much, other people are already accustomed to saying, "Oh, if it gets dirty, I remove it with an acid cleaner" and "I'm polishing it because it contains an abrasive because it's not coated" ^^

I was helped in various ways by the advice from all of them, but there aren't many people like me who are about to die saying "I can't get rid of the dirt!" (Laughs).

In the first place, is it greedy to hope that "I use black carrera for square training such as a steady circle, but I want the car to be shiny normally"?

Still, I want Black Carrera to always be shiny. And I also want to practice steady circular turning with black carrera.

Of course, it doesn't matter if it gets dirty during training, but I want you to get it back shiny after washing.

Ah! I remembered here.

When I thought about it, my husband also participated in the same environment on that day. You should check the car at that time.

So, confirm.

My husband participated in Fairlady Z. Since the Z is already used exclusively for open space training and circuit driving, I always use the automatic car wash machine at the gas station to wash it quickly after training.

I washed it immediately after training this time as well, so I'm sure it's clean. Yeah, it looks beautiful ↓

While thinking, "No, no, but" I approached and took a closer look, how! !!

Wow.

It was dirty. So much. The same white stains as black carrera are perfect. This is just like an ion deposit.

Since the color of Z in my house is yellow, I think that if it was a black car, it would have been in a pure white state like a black carrera, just because you can not see the dirt unless you look carefully with appropriate light adjustment.

Because Z is also after allIf you wipe it with an acid cleaner in the same way, This is this. Do you understand?

The right side is wiped with a cleaner, and the left side is still. Actually, you can see how the whole thing was dirty white ↓

In the end, Z also cleaned up the whole and returned shiny ^ ^

It seems that when I was soaked in water as much as my husband and I on that day, it was so dirty that it turned white.

* It can be said that our car was the dirtiest because we probably ran the watered Gymkhana field for the longest time on this day.

After all, why did this happen only this time even though I was bathed in the well water of the same Tsukuba Circuit every time?

• "Mud, sand, tire scraps, and rarely oil" on the road surface may be mixed with the sprinkled water, so something was mixed up this time.
• The water that was bathed dried faster than usual due to the right temperature, humidity, and climate, and it stuck as if the well water had been left on the car body for a long time.
• There was a change in the quality of the groundwater in Tsukuba (← I'm still saying (laughs))

I came to the conclusion that I can only think of such things.

How to avoid leaving an ion deposit

The conclusion of this time is that the only way to deal with these problems is to "flow immediately".

It is important that the water (well water) is flushed before it dries, and even if the same well water is used for flushing / car washing, such ion deposits can be obtained simply by removing the water by immediately towel-drying. It seems that it is possible to avoid sticking to the point where it cannot be taken persistently.

Of course, if you wash it with well water, you should wash it again with water that is not well water, but for the time being, I think that the above measures can be taken immediately on site.

Well, what happened to my Porsche 911 that turned white at the end was that I had you polish it all over again and have it coated anew.

It's already shiny now ^^! (So I'm back in a good mood. Simple!)
