Great for Washing Without Scratching
I’ve been using the Optimum Big Red Sponge for a while now, and it’s been fantastic! It washes my car thoroughly, lifting dirt and grime without any issues. The best part is how gentle it is on my car’s paint—there’s no scratching, even with moderate dirt buildup. Whether I’m using it with a rinseless car wash or traditional soap, it works perfectly every time. The large size also makes the job quicker, and it feels sturdy and reliable. Highly recommend this sponge for anyone looking for a safe, effective way to wash their car!

wash in cold water cycle, store in a gal. size freezer bag
I have been using ONR to wash my car exclusively for over a year now. I was using shaggy, no binding microfiber towels to do the washing by soaking three of them in my pail and changing them out so each large panel was done with a fresh towel. I recently purchased the Big Red Sponge and I am very pleased with my purchase and its efficiency. I can wash the in less time (30 minutes or less) and the sponge actually cleans better than the towels. In SW Florida, dust and pollen are the problems us “Car guys” have to deal with, there are times that pollen falls in drifts! I live in a condominium park under an open shelter so without regular washing my black car looks “Dusty Yellow”. This sponge holds the ONR much better than the rags and holds that dust until it is replaced in the pail where it is released. I then use super soft microfiber towels to dry and polish the panel before moving on. I highly recommend this product if you are persnickety about your car’s appearance.

Expensive But Worth It - Great For Waterless Washes
I love this sponge - forget about the price for a moment - it works great with waterless washes or even with a basic contact bucket wash - holds the suds and when rinsed the dirt is gone

Great quality sponge for Rinseless wash
I like this Red Big Sponge (RBS). and would recommend anyone who needs to do rinseless wash. (I recently do rinseless wash every weekend with this product and N-914 Rinseless Wash) Will RBS scratch paint? In my experience, BRS with proper use of Rinseless wash solutions including pre-treatment could minimize the risk of scratch. At least, I do not see any major scratches on my paint. Apex Detail's YouTube video tested how various wash media possibly scratch paint. Any contact wash could possibly scratch, but the author concluded that BRS does a good job. Will dirt be really released from RBS? Personally, BRS does a good job to release dirt. When I washed BRS in a bucket with a grit guard, black stains on BRS (dirt) are relatively easily gone. Also, I found that test of Source Garage’s YouTube channel is great. He checked whether he can find any dirt or mud on BRS using a microscope after it is washed in a bucket. As a result, he concluded that BRS does a great job and most trapped dirt is released. How durable is it? How to clean and maintain it? So far, I found it quite durable. I used it every weekend for a month. BRS’s quality has not changed at all. After use, I just washed it with water and try my best to remove dirt. I found the Rag Company’s YouTube video helpful to learn how to maintain it.

Best Sponge with ONR
I am an avid Detailer who spends a lot of his weekends detailing cars since his 9-5 doesn't pay enough. Optimum Polymer Technologies and their Big Red Sponge and Optimum No Rinse has made my detailing process a whole lot faster, economical and cleaner! Following Yvan's waterless wash method, I was able to wash, clay and wax this BMW e36 M3 in a little over an hour! No swirls, scratches or fuss which makes me VERY happy. I would say the BMW had a months worth of dust, dirt and pollen on it since it sits outside all day 24/7. As long as you do one pass, flip over, do another pass and then rinse with ONR in a 5 gallon bucket with a grit guard. The big red sponge will not scratch or swirl your paint. Pro tip: With it being a new sponge, soaked it in a 5 gallon bucket filled with water over night be use.

Best sponge for rinseless
This sponge is pricey but works like no other. I've had a previous one for 2 years using it once a week for rinseless washes. It was getting worn so this new one is replacing it.

Excelente para hacer un lavado rinseless
Excelente esponja para lavar mi auto. La compre con un poco de duda, sobre todo porque nunca había usado una igual. Pero funciona de maravilla utilizando rinseless. No raya la pintura y es muy fácil liberar la suciedad al enjuagarla

The perfect accompaniment for ONR
"Thou shalt not wash car with sponge" is the most important of the Ten Commandments for detailing enthusiasts, but the Big Red Sponge (BRS) aims to change this perception. Based on my experience, it has. The BRS paired with Optimum No Rinse (ONR) has become my go-to maintenance wash method. It's quick, requires minimal kit, and most importantly is safe for paint. I was skeptical before, but now I'm a convert. All hail Optimum!
