Cleaning Fender wells (liner under the fender)

[TNMIKE46]

I was just thinking here and thought about this question. Searched the forum and nothing comes up. What do you guys use to clean under the fenders.

I'm sure pressure washing will be one answer but I was wondering if anyone uses specific cleaners. Then after cleaned what do you use to make the plastic look like new.

Just wondering?!

Good question, I'm interested in what people will say. I usually just use AP cleaner, get a brush (I have the long handed one from Mothers), scrub and rinse. I use Meguiars Ultimate "Back-to-Black" for the dressing. Thinking of switching to the newer product from Meguiars that's in a spray form.

I detailed 3 vehicles this past weekend, and after 5 rare days of rain they were all thrashed inside the wheel wells especially.

I spray Megs D101 APC inside the wheel well, then I hit it with the Mothers Wheel Well Brush. If you’re interested in getting your wheel wells right, then I highly recommend this brush.



Once I rinse them clean, I spray them with Hyper Dressing @1:1
It self levels so there’s no need to wipe it down, just spray & walk away.

As far as that brush, it must be used correctly or it’ll frustrate you and you might end up hating it... It’s not rocket science, but it matters.

Start at the bottom of the wheel well with the brush, like this:



Sometimes you don’t or can’t make it all the way around, so start new on the other side, bottom to the top:



If you try to enter like this, you’ll fail nearly all the time and you’ll wind up hating wheel wells altogether... Not to mention you’ll probably wind up scratching your paint.



See how my wheel wells always look good? That’s because of the Hyper Dressing.

That brush works fine with that HUGE fender gap. Good luck using that on a sports car or a lowered vehicle.

This reminds me that I need to jack up my car, pull the wheels, and get in there for the upcoming Mopar show in early March.

I pretty much do what Eldorado does. Generally, I don't clean them, I just hit them with Meg's All-Season Dressing. Even when you clean them, you have tar remaining. That's problematic because the same stuff that dissolves tar also can potentially dissolve plastic. So I've lowered my expectations to "make it look good" rather than "make it perfect."

P.S. You can access most of the wheel well by using a jack, giving it a few pumps, and leaving the wheel on. Just use the jack to create some space for yourself.

I’m still looking for a satisfactory dressing for the wells that will put up with at least a little rain. Hate to dress them only to see the dressing just wash off.

Use a dishwashing aka toilet bowl brush.

What have you tried and @ what dilution?

[Bill D]

I’m currently using PERL at full dilution. In the past I’ve tried nearly every water based dressing. I don’t like oil based ones because they attract dust

On my wife’s F-150 I was putting Mc’Kee’s Tire Shine with Si02 on the tires and decided to hit the inner fenders with it. I was impressed. It lasted quite a while and made cleaning them much easier for a few weeks. A little off point but this product has really impressed me on tires. I bought it just so I would have a product I could put on quickly. I figured the Si02 was just a gimmick. I don’t know if it’s the Si02 or just the formula in general but I’ve been extremely pleased with this product. After I saw how it did on both the tires and inner fenders I bought a gallon.

If that product fares well in wet conditions I will consider it
