T.R. Industries Metal Cleaners & Polishes
Professional-Grade Metal Care from T.R. Industries
When it comes to keeping metal surfaces gleaming — whether on an RV, a boat, a vehicle, or household appliances — few names carry the depth of expertise that T.R. Industries has built over more than five decades. Founded as a division of Granitize Products Inc. in the 1970s, T.R. Industries is a family-owned and privately-held company based in South Gate, California. That heritage of surface science is what sets their metal cleaners and polishes apart from generic shelf products.
Roots in Industrial Surface Treatment
T.R. Industries didn't start by chasing the consumer market — they earned their reputation working at the manufacturing level. T.R. Industries was originally founded to provide mold release products for manufacturers of fiberglass, reinforced plastic, and cultured marble products, and their complete line of professional-quality surface treatment products were designed to produce the best finish possible at maximum efficiency and minimum cost. In response to requests from automotive, marine, and recreational vehicle manufacturers, T.R. Industries then developed a product line of surface care products for continued maintenance after the sale. That industrial-first thinking means their metal cleaners and polishes are formulated with professional performance in mind — not just shelf appeal.
The Gel-Gloss Line: A Multi-Surface Metal Care Workhorse
The flagship product family most associated with T.R. Industries' metal cleaning and polishing capability is their Gel-Gloss line. Brass, chrome, stainless steel, wood, glass, leather, and man-made or natural stone surfaces can all be maintained with the Gel-Gloss product line. That cross-material versatility makes it a go-to for anyone maintaining a vehicle, RV, or boat with a variety of metal trim and hardware.
What makes Gel-Gloss particularly effective on metal is its formulation philosophy. It combines powerful cleaning agents with effective Carnauba waxes to produce the highest surface luster possible, removing water spots and polishing to shine and seal fiberglass and acrylic surfaces. The non-abrasive cleaning agents remove oxidation and light scratches while leaving a protective wax coating — critical for delicate chrome trim and polished stainless steel that can easily be damaged by harsh abrasives.
The Gel-Gloss No-Streek Glass & Metal Cleaner (available in 8 oz. and 19 oz. aerosol formats) extends the line into chrome and metallic glass surfaces. This cleaner is used to clean and polish glass, chrome, and metal surfaces. It is a professional-grade, one-of-a-kind foaming aerosol glass cleaner and polish guaranteed not to leave a streak.
Stainless Steel & Appliance Care
T.R. Industries also produces a dedicated S.S. & Appliance Cleaner under the Gel-Gloss umbrella, targeting the stainless steel surfaces found in kitchens, RV galleys, and marine cabins. These formulas address fingerprints, water marks, and oxidation — the everyday enemies of stainless steel — without stripping protective finishes. The Gel-Gloss line is excellent for RVs, tubs, showers, spas, basins, and stainless steel surfaces.
