The Rag CompanyUltra Black Sponge

Good sponge- sits well in hand. Seems to work well with ONR wash solution to effectively clean your car with no scratch issues. Not cheap, but you need to right tool to do this job.

Surprisingly small for the price, as others have said, you need the right tool for the job. Arrived in UK well ahead of the delivery estimate too, just in time for hosepipe ban!Having watched many YT videos - recommend the rag company - I tentatively used this with 5 litres of water and 4 capfuls of ONR wash and wax.I did pre-spray the panels first with some solution in a simple pump-sprayer. I then soaked the sponge in the bucket, partially squeezed it out, and then 'washed' a panel.Amazing performance.My car had done 1500 miles since the last wash 2 weeks ago, so was dusty and with dead flies etc. The sponge and ONR got this all off. Admittedly it took a couple of goes on some big dead bugs, but the whole car was cleaned very quickly. I washed 1-2 panels and dried them before moving-on, as it's super-hot right now. Sparkles and surface feels smooth and protected.The sponge and ONR feels very slippery on the surface, with no drag and no friction. I used a normal pressure, nothing special. On the black car it was really easy to compare the clean and unclean panels, and to watch the transformation.With one bucket of 5 litres, and the 4 capfuls, I had enough to wash both large SUVs at home.Dried with a large microfibre drying towel.For the wheels I used an old microfibre cloth at the end, so as not to dirty the sponge.Emptied the remaining solution onto the lawn - as per the OPT website !I've been valeting my cars for 40 years, and I'm super impressed with the Optimum range, and heartily recommend the sponge to go with it. It has to be the most environmentally friendly and economical approach to car cleaning. I'm sure this will be a different story in the winter, but for now, with a hosepipe ban, this product combo is unreal.

I have gihugant hands. This works perfectly for me. I have more control over this than the common red one. Would buy again.

Used this instead of multiple microfiber towels. No more turning over the microfiber towels multiple times, with this sponged just swipe on the paint, then clean in the bucket and wipe the paint dry with a MFT. Does save alot of time and cleans better.

Quality product. Does what it’s supposed to do.

I was very hesitant about switching to a wash sponge like this. I don't use it in every situation but if you get used to how to use it you can wash a vehicle very quickly with it. And the curves are very nice around body lines. Is thick enough to not create pressure points and cleans very easily.

Tried this on a few cars, including a dark color. Did a great job getting the surface clean, and rinsed freely with each squeeze into the bucket. Didn't notice any additional marring or swirls compared to a mitt wash.Really wish it was yellow/orange, or a light color. But for now I wash one panel, and flip it halfway, rinse and squeeze in the bucket, then into the soap bucket.Before this I would use several wash mitts with just 1 soap bucket. I'll continue to use wash mitts alongside this for things like door handles, tight spots etc, but for flat and curved surfaces so far it's a winner.In terms of laundry and storage, it's a wash since I'm using a 2nd water bucket but using less water and drying time. Very easy to clean/dry as well. Some rinsing and squeezing under water and it self cleans and you can squeeze most of the water out, then stand it up and let it dry overnight.Wish I had waited a few days to order it, now it's on Prime for 20 bucks with free shipping, I paid about 27 bucks but that's not the products fault.All in all, glad I bought this. Never been big on sponges for car washing, but this has already proven to be a safe way to do it with the new cell tech they have going on. This isn't your walmart or pep boys sponge! Only time will tell about durability, but for the price if I get a year out of it I'll be very happy. Another good product from The Rag Company.This would be 5 stars if it was a bright color that allowed me to more easily see soiling, and when it's truly rinsed clean.
