I've been using Meguiar's Wheel Brightener for some time now, and having tried several other wheel cleaners, I can honestly say this is the best one I have tried. The reasons I like it so much are two fold: 1: VALUE. It comes in a 3.78 litre bottle which you dilute 4:1 (4 parts water to 1 part Wheel Brightener) giving you a total of 18.9 litres of wheel cleaner! 18.9 litres for approximately £30! Compare that to Meguiar's ready mixed Hot Rims Wheel & Tyre Cleaner which is £10 for 710ml, and you see what a bargain this is. 2: CLEANING POWER. You llitteraly spray it on, leave it 30 seconds or agitate with a brush, then rinse off, that's it. Your wheels are left gleaming. Yes it's an acid based cleaner so I would imagine it will strip any sealants / waxes you put on your wheels, but if you clean them once a week with this stuff, you won't need to seal / wax your wheels. It won't get the absolutely baked on bits of dust off, you'll need a separate product for that, but if you've got clean wheels and want something for cleaning them on regular basis, look no further. I have uploaded the below video to YouTube to show how effective this was in cleaning my alloys that I had purposely not cleaned for 4 weeks: https://youtu.be/1y8SVQLNFuM

Took all the muck muck off my rims after driving through construction site. I needed to use the brush along with this to get them clean but i do that most times. I think it is a good product for the price you pay.

Great Product..... Time Saver on the wheels!!!!

I finally tried this. I have read this has acid in it, and was afraid of it. If there is acid in this, it didn't hurt my hands when I used it, but the wheels look brand new. Buy this, you will really like it.

When you've got some heavy brake dust and yellow staining from neglect and/or winter use, nothing in the gentle "PH-balanced" category will work like this old-school stuff. Yes it's not ideal for your health and I wouldn't want to be using it day in & day out, but when used with some agitation with a wheel brush, the result is fantastic. And I don't have to be sparse with applying it because it's so economical when mixed 4:1. Highly recommend.

With the results you get from this and the price point, not sure how you would choose to go with anything else. The rims come out sparkling like not even a speck of dirt has ever touched them. Any rim I've used this on looks brand new afterwards (unless the rim has never been cleaned in many years - then thats another story).

It works well enough. It still took lost of elbow grease to get these 1992 wheels clean enough to repaint.

Great results ! A must for easy break dust removal.

This product is designed to get the brake dust off your wheels. It works very good. I lo ve meguiars products.

This product does not work as advertised. I get better results with a Brillo pad and a bottle of .99 dishsoap.

OMG this stuff is awesome,Not for use on Aluminum wheels but everything else it KICKS BUTT on! My new go to when wheels come in that are TRASHED.

even though this is not good for uncoated aluminum wheels I think its GREAT for those DD coated wheels. Takes off grime most other cleaners wont.

This wheel cleaner is the best i have ever used. it killed the brake dust and made my wheels shiny clean. it even removed rust from my brake disc. this is the BEST Wheel cleaner!!!!!

I've had a few people come to me asking what can be done to their wheels. They have tried other wheel cleaning products that havent been able to cut through the brake dust left on their wheels. The effort with light brushing and a minute of dwell time ends with the shine and cleanliness rivaling a new wheel.

If you have wheels that are BAD DIRTY, this is the stuff to use. None of the color changing products can touch some of the stuff this stuff will clean. Granted this cleaner is not safe for all wheels, but you aren't going to find one any better 9in cleaning ability) I don't think.

Dilute to your strength requirements. Works great! Took off brake dust that $25 bottles couldn't do. I mix two bottles. One weak and one strong. Good deal for a gallon that can dilute to make many gallons.

I dilute this product approximately 4:1 (I don't measure it out perfectly every time) and it works fantastically. Spray on, let it sit for a couple tens of seconds, brush it, and rinse. Works great on wheels, tires, wheelwells, undercarriage areas, and chrome. For less than $20/gallon, you can't go wrong.

First off, DO NOT GET THIS ON YOUR HANDS, or feet, or legs. If you do, wash it off quickly. Other than that if you have factory wheels you will not find a product that removes brake dust quicker. Super awesome on chrome, painted factory wheels, and clear coated aluminum. Spray, agitate, blast off. Note, will stain your driveway a little if not rinsed off. Dilution rate makes this uber cheap when compared to other cleaners. And I use it everytime I clean my BBS wheels (2x a week) with no problems.

While this product may be effective, it contains Ammonium Bifluoride which can have serious long term effects on your health. Please read up on this chemical before you consider using, e.g. here: http://www.carwash.com/article.asp?IndexID=6631269 . There are so many safe and effective alternatives today.

I bought this after hearing professional details refer to it all the time as the absolute best occasional wheel cleaner to get wheels back to pristine condition. Boy are they right! This is a product I use once a twice a year. As I understand it's not good to use frequently as it can eat away your wheel finish. However, it also completely melts dirt/tar/and brake dust no matter how baked on it is...is really is amazing. Spray on, run a wheel brush over your rims and rinse. Perfectly clean. No scrubbing or anything needed.

I used this mixed 4:1. I did a great job on my coated aluminum wheels. Meguiars suggest not to be used on uncoated aluminum. Read the cautions and use it. You love the results.

this product really works fast and will leave the worst looking wheels appear new again. it is a true spray on and rinse off product. please read cautions as this is a serious product and should only be used on the wheels that are deemed safe by Meguiars. for the serious detailer this is a real time saver. considering you can mix this 4:1, a little goes a long way.
