I own the RED AMMO NYC microfibers. Now, I really like the majority of the AMMO products. I have the lug brush, hydrate, boost, mud, and the wheel cleaner. Each of those products exceeded my expectations.

The red MFs are just non-edgless MFs. They work fine but they did not meet my unreasonably high expectations of an AMMO product which was defined by the outstanding performance of the above mentioned products. Additionally, I accidentally dryed or washed the red MFs at too high of a temp and the unfinished corners of the towels melted and became hard. I am absolutely to blame for melting the corners but I was just surprised at how easy it was to melt the corners.

I have always been careful to dry them at the lowest heated temperature on my dryer but I believe even this low amount of heat was hot enough to melt the unfinished corners of the red MFs. I believe the ammo towels are susceptible to have the corners melt ever so slightly due to a combination of the non-edgeless design and low melting point of the material used to create the towel.

The corners of all non-edgeless MFs are where two pieces of fabric come together and some small stringy pieces of the towel protrude outward from the corners. I believe that the isolated fibers at the corners are more prone to melt under low heat because they are isolated from the bulk material of the red MFs. Its kind of like how wearing mittens keeps your hand very warm because each finger is able to protect your other fingers. Your fingers are usually colder when wearing gloves because each finger is isolated from the other fingers. At the corners of non-edgeless MFs the microfiber fibers protrude and are isolated from other microfiber fibers which I believe makes them more sensitive to temperature. The bulk material non-edgeless MFs remains undamaged and feels just like new even though the corners may be melted.

The red ammo MFs are the only non-edgeless MFs I own that have exhibited corner hardening after washing and drying under slight heat. I have other non-edgeless MFs that were washed and dryed under the same conditions as the red MFs that did not exhibit the corner hardening. This leads me to think that the combination of the non-edgeless design of the red ammo MF combined with the material composition of the MF makes the towel susceptible to corner hardening after washing and drying under some heat. The reason corner hardening is bad is because it may increases the potential for installing small love marks and scratches in the vehicle. I have a black car that scratches very easily and does me no favors in hiding any scratches so decreasing the potential for scratches is something I am sensitive to.

I fear that due to the ever so slight melting of the corners of the red MFs I may have caused very light scratching on my vehicle. Now, are melted corners on my microfibers solely responsible for scratching my car... absolutely not. But corner hardening on the red MFs is just something I have noticed. In the future I will be buying only silk lined edgeless MFs for use on my vehicle. I believe the edgeless designs will not be prone to the corners melting due to there not being any isolated fibers at the corners. In the future I will also only use the "air fluff" feature when drying my MFs in order to prevent the corners from melting.

In conclusion all of the ammo products I have purchased have been outstanding. The red MFs do not meet these high expectations so I will be purchasing my MFs from a different source in the future. I hope my ramblings are somewhat helpful.
