Neoglide
A branded closed-cell foam wash material from Kirikian Industries used on wraps, mitters, side brushes, and top brushes in place of cloth; it does not absorb water and needs lubrication so it glides rather than drags on the vehicle surface. Marketed as a safer, gentler friction medium and central to the "soft touch is safe" argument for friction washes. Also sold under "Ryko Neoglide" branding via retrofit kits, suggesting a historical Ryko relationship not fully clarified.
*Also known as: NeoGlide; foam cloth media (the generic category it belongs to).

Permacolor (Permacolor / Durasoft / Microplush)
A family of registered Sonny's trademarks for washing/drying/polishing curtains and strips - branded names for tunnel curtain/strip material (the fabric-like strips hung in wash bays to direct water/soap and buff the vehicle). Permacolor and Durasoft cover washing sheets/strips; Microplush names a plush/microfiber-style curtain material. Merged here because all three are the same goods class and are only variants of one another. "Permacolor" also appears in the CarWash College glossary as a near-synonym for no-fade cloth.

Soft-Touch
TERM WITH TWO CONFLICTING DEFINITIONS - both recorded. (1) Majority/manufacturer usage: a friction wash using gentle media (foam brushes, cloth strips, closed-cell foam like Neoglide), as opposed to touchless/touch-free. This is how AUTEC, Belanger ("Freestyler Soft-Touch"), D\&S ("IQ Soft Touch"), Istobal, and detailing trade press use it. (2) At least one industry-facing source (Car Wash Advisory's "Types of Car Washes") instead defines "soft-touch" as a synonym for touchless/no-contact. Treat reading (1) as the majority usage but verify which sense a given source means.
