Great sponge, used ONR method and will be sponge again when needed.

I like to use these sponges to clean the lower rocker panel area of cars as they are typically very dirty and i do not want that dirt and grit in my good wash mitts. The sponge collects dirt very well, but also releases it pretty easily in your rinse bucket. However, they do take quite a few good rinses to get all of the soap back out before drying.

A lot softer than it looks in the picture, especially when its damp. Grouts are nice for corners and edges but they probably reduce the durability of the sponge. Its decently priced so having to buy more shouldn't be a big deal.

This thing is great. It holds gallons of water and suds. my truck was fairly dirty and the sponge cleaned up very well. I used it with two buckets and grit guards. Works great!!!

Works great. Holds lots of suds and water and is excellent with a grit guard.

When I got my first DI order I was intrigued, but skeptical about the sponge. I thought there was no way it would be better than the sheepskin wash mitts, but now I'm a convert. I still use the sheepskin mitt for tight areas(grilles, etc), but the sponge holds so much more water and suds its unbelievable! It releases contaminants easily and i never worry about not having enough suds.

LC Grout sponge is an ode to the old and new. Old sponge design that creates lots of suds and absorbant. New material of grount/foam that absorbs dirt without keeping anything at the top to marr your paint. I like how it create suds at a mere squeeze. You can split these sponges so they work like other higher priced foam wash tools. These might stain from Optimum No Rinse, the best way is to split wash it with regular car soap. These are extremely resilient if you abuse them around edges, etc.

To all of you who thought like I did that this is a regular sponge. It is far from and ordinary sponge, and does an excellent job makes cleaning so much easier.

Aggressive enough to remove dirt but gentle enough to not scratch paint. Design sheds contaminants well when used with a grit guard. Overall this is the best handwash sponge I have used to date

I was never one for using a sponge, until all of the true detailers (including this site) said it was the way to go. I picked myself up a couple of these guys, and they are great. Holds a good amount of solution and doesn't seem to scratch at all. Skeptic turned believer

Good-volume sponge and dirt flushes out relatively easily. Used it with Chemical Guys Citrus Wash & Gloss with good results.

one of my favorite sponge to wash the car. soft and releases dirt very well.

The Lake Country Blue Grout Sponge and Optimum ONR are like a match made in heaven. Only which the boys at DI would suggest to LC to manufacture a larger size of the sponge to facilitate cleaing of trucks, SUV's, etc.

Works great with ONR. It soaks up water really well and releases dirt very well.

Huge fan of sponges in general and despite a good design on this one I think it's too hard for my liking. Been using various popular VERY soft grout sponges and thought I'd give this a try but I worry it will marr softer paints

Easy to grip, holds lots of water/soap and releases the dirt well.

Really like this. My only problem is that I've used it for 3 washes, and it's almost completely torn in half.

Great sponge,great price works well. I'd highly reccomend it.

This sponge paired with ONR and a two bucket method with grit guard inserts is a great combination to get any car clean. I'll be purchasing these in bulk form now on.

I got rid of all my other microfiber mitts and sponges when I tried this. After a New England winter, my black vehicle was in the best shape ever using this sponge. Love it. Very safe for the finish and very easy to manage.

I would buy this again, but knowing full well that it will only last a couple of washes. The first one I had I twisted when I wrung it out and that ended up breaking the sponge in half. But if you're careful with it, it will certainly get the job done. All in all a good sponge, but I wouldn't say 'great'.

I usually use a mitt, but saw these sponges and decided to give them a try. I used this sponge with the 2-bucket method. After washing a really dirty car, my rinse bucket was filthy, the wash bucket was still clean. Great sponge.

Excellent sponge. Soft & releases dirt very well. A bit more expensive than the grout sponges you'll find at the home improvement store - but more convenient & has the slits (dirt release).

Use sponge for first time using ONR and it worked great. Very soft and the slices in it are genius.

i was very skeptical at first of grout sponges in general but after several uses i dont think i will ever wash with anything else.

Great wash media! I use it primarily for ONR-washes (90% of my washes)

Best sponge and may be my favorite wash tool. I prefer it to MF mitts I like the size and shape. For me it is not too thick. It retains soap better than anything I've ever used and makes beaucoup foam with a simple squeeze. Very easy to shed grit with Guard. I use pad cleaner spray periodically to keep as new. Buy several on sale. They wont disappoint IMO.

After reading reviews, I thought it was going to be laborious to use, but after using it with a solution of ONR, I absolutely love this thing. Fits great in my hand, I thought it looked big at first, but after using it I instantly changed my mind. The cross cut pattern also really helps out when releasing dirt from it, makes it a breeze. I highly recommend for ONR washing

Great for washing! I recommend two of them!

Nice sponge but too thick....I cut it down the middle to make it thinner....Now, I have 2 thinner sponges and they work great...

I have to agree with the review from 3/28/09, I used it this morning and it did a great job.

I used this sponge with some ONR and the 2-bucket method. It felt harder than I expected, but after washing a fairly dirty car, my rinse bucket was filthy, the wash bucket was still clean, and there were no swirls whatsoever in my paint. While I skeptical at first, this sponge did a GREAT job and is sturdy.

Good sponge. Used it to do some heavy washing and liked the results.

I think it felt a bit too heavy and big at first, but it works great and releases the dirt well. But it could be thinner.
