Reddit mentions of The Rag Company (10-Pack) 16 in. x 16 in. Professional EDGELESS 365 GSM Premium 70/30 Blend Microfiber POLISHING, Wax Removal and AUTO Detailing Towels (16x16, Royal Blue)

The Costco ones are perfectly suitable for general use, They're about 350-360 GSM and as far as "cheap" towels go, they're a better bang for your buck than many others out there. That said, they're 80/20 blend, not 70/30. (I'm not sure where you saw 70/30? But unless they did some major tweaks recently, they're 80/20 like they've always been)

Those CG towels are extremely popular because of their price-point. They're 70/30 which puts them a notch above the Costco towels, but they're pretty much same GSM.

Our Spectrum towels are 70/30 blend and 420 GSM, which is why you see them costing a little more than the other two. (Not sure what you mean by small, though-- They're 16" x 16" just like the Costco towels)

If you want something from TRC more comparable in spec to your other choices, I'd steer you towards the Edgeless 365. It's 365 GSM as the name implies, with a 70/30 blend and an ultrasonic-cut border. (Which gives it the edge for detailing purposes-- Pun intended)

If you're looking for something cheaper, we also do Edgeless 300's and Edgeless 245's. But I find detailers tend to like the 365's best as an all-around useful towel.

Anyway, I'm sure any of these will suit your needs, I just wanted to make sure to weigh-in! :P

It's just the towels are too thin. ONR is perfectly safe even if your paint is heavily soiled, but you're spraying the car down before hand knocking off any loose debris so that's a plus. I'd rather use the towels that I bought from Walmart than the ones they sell on Amazon for cheap. Basically the Amazon microfibers are throwaway towels, used for interior, engine bay, and wheels. However I do use them to do spot paint correction. Things like putting some compound and getting rid of the scratches behind the door handle, using Meguiar's ScratchX and getting rid of minor scratches. I suggest getting the Eagle Edgeless from The Rag Company, in my opinion they're the best (even though I don't have them). I have the Creature Edgeless ones and they work just as great. Or if you're on a budget get these, I'm not sure what the equivalent name for these towels are on The Rag Company website, but they should be good too. Also I recommend getting a Nanoskin Sponge or you can get the mitt too. It's a clay alternative and lasts forever (make sure you don't let it face down or in the sun, my friend left his in the sun and it melted).

Edit: I just re-read your post and you know what's funny? I actually just cleaned the same exact car as yours today, but it was black!

okay so like the comment below 303 is simple and easy. I don"t use it much as its not readily available here in Toronto.

Things i do use:

For the dash board and any plastic inside the car i use:

OR

For the carpets i do 2 thing when i am in a hurry ill use:

https://www.amazon.com/Turtle-Wax-50572-Rubber-Cleaner/dp/B00PKE6NNY/ref=sr_1_12?ie=UTF8&qid=1487704985&sr=8-12&keywords=turtle+wax+interior+cleaner

Just spray some on the carpet and after a quick vacuum then do a good vacuum job this can take like 30 mins once you get the hang of it.

when i have time i use:

https://www.amazon.com/BISSELL-1400B-Multi-Purpose-Portable-Cleaner/dp/B0016HF5GK/ref=sr_1_2?ie=UTF8&qid=1487705069&sr=8-2&keywords=bissell+little+green

The second method is simple just follow the instructions it came with and this item usually goes on sale there are better ones that keep the water heated.

They also both give the car a nice smell after cleaning i don't have leather seats so i can say much about it.

as for windows there 2 steps i do as well:

I use

https://www.amazon.com/Invisible-Glass-Premium-Cleaner-91164/dp/B0007OWD2M/ref=sr_1_2?ie=UTF8&qid=1487705440&sr=8-2&keywords=invisible+glass

Then polish the exterior and where is no tint with

The second step is a bit tedious so if you are not comfortable stick with step 1.

The thing that also really good to have is good clothes for cleaning the more the better Micro fibre cloth's are the best.

and for glass:

After wiping the class with step one and then its dry i usually just follow up with a dry microfiber cloth to pick up any little dirt i left behind.

If i left anything behind let me know ill make a full post once summer comes around with maybe a video of sorts but there is alot of information also to r/autodetailing wiki post and sorry for the format if its not up to standards this is my first long post.

I went with The Rag Company Professional Edgeless towels in combination with a spray detailer to add a little lubrication while drying. Keep in mind, I'm still new to this, so I'm looking for suggestions as well. I've just read really good things about their microfiber towels.
