Hi, I'm Mike from 1AAuto. We've been selling auto parts for over 30 years.

What's up guys? Today we're gonna test what brake fluid is gonna do to your paint in these different time intervals. This vehicle is older, it doesn't have good wax on it. If you have a car with good wax on it, it's clean, wiping it off right away should not damage the paint. But we're gonna see what it does to this vehicle.

This is Dot 3 brake fluid. I'm just gonna suck a little bit out. Just drip it on here, and I'm gonna wipe it up right away. Just take a little cleaner, wipe it up. A little bit of soapy water, clean that up. And it looks good, nothing happened to the paint.

Now we're gonna put a drop on here. We'll do this five minutes, 10 minutes, 30 minutes, one hour, three hours and six hours.

So now it's been five minutes, we're gonna wipe off the five minute mark. Use some cleaner and a rag and wipe it off. It looks like it made some marks. The paint still looks okay, but the clear coat is probably ruined. If there was any clear coat on this car. The clear coat is definitely stained.

Now we're at 10 minutes, and we're gonna spray this. Try not to spray the other one off. Just using the soapy water cleaner, wipe it off. It looks like we definitely have a stain at 10 minutes. And the stain looks definitely worse than the one at five minutes, but not much worse.

All right, so now we're gonna wipe off our 30 minutes. Just spray a little more of our cleaner on here, wipe it off. It definitely stained it and it looks a little bit worse than the 10 minute.

Now we're at one hour. I'm gonna spray this section off and wipe it off. It looks like even more of the clear coat is coming off, it's stained.

Now we've let this sit three hours. We'll clean this one off, spray it with a little bit of soapy water, wipe it off.

Now we're gonna wipe off the six hour. As we can see, no matter which time it was the brake fluid has done damage. It looks like even after five minutes it has done damage. So the good thing to do is not get brake fluid on your paint.

After 30 minutes it's pretty much the same, it doesn't really look like it got much worse after six hours. But it looks like it's not a good idea to get brake fluid on your car.
