POR-15 Cleaner Degreaser (formerly marine-clean) cleans and degreases in one application without leaving residues, noxious fumes, or flammable solvents. No other cleaner works as fast or as well. It makes petroleum-based cleaners almost obsolete because POR-15 Cleaner Degreaser can be diluted with water up to 4 to 10 times its volume while remaining more potent than other cleaners. POR-15 Cleaner Degreaser removes grease, oil, mildew, algae, musty odors, soap films, wax. Use it to clean canvas, vinyl, nylon, holding tanks, grease traps, auto parts, and more.
Adhesion is important with most paints but has to be perfect for POR-15 Rust Preventive Coating to achieve its maximum effectiveness. A solvent wipe before painting didn't work with POR-15 Rust Preventive Coating; in the lab we found it did more harm than good by leaving a residue that didn't help with adhesion or appearance. We had to come up with a substance that would clean metal without leaving a residue. What we developed, POR-15 Cleaner Degreaser, contradicts all accepted theories about metal prep products: its water-based, not solvent-based and it cleans without leaving residues. In laboratory adhesion tests, our POR-15 Rust Preventive Coating using POR-15 Cleaner Degreaser first to clean the bare metal far exceeded every other prep product we found in the marketplace.
TIP: When applying to Aluminum or other alloys for clear coating, first test on an inconspicuous area for staining or discoloration. If staining or discoloration occurs, dilute Cleaner Degreaser 50% with water and retest.
Step 1: Clean it with POR-15 Cleaner Degreaser
“We used the POR-15 Cleaner Degreaser to remove any surface oils or other contaminants on the metal. After primer, the correct semi-gloss black paint from POR-15 was applied with a spray gun and compressor on all parts of the frame.”

Haven't used it yet. Received leaking, but still usable quantity. A replacement was sent, bit leaking, again. UPS driver said not to accept it, and he would send it back. Obviously , shipping must be a problem with these products, but this company is quick to replace any discrepancies. Thank you. As for the using the product, "the jury is out". I'll get back to you on that.
I have a moped that sat in a barn for 28 years with gas in the tank. Needless to say it was a tank of sludge. I put in a strong solution of one part water to one part degreaser. After 24 hours I drained a gallon of black liquid. I rinsed the tank and it was spotless inside. Very impressive product.
POR-15 Cleaner Degreaser should be diluted with hot water. Four parts water to one part Cleaner Degreaser (4:1) works well for most jobs; but may be diluted up to ten parts water to one part Cleaner Degreaser (10:1). After using Cleaner Degreaser rinse job thoroughly with water. Metal Surfaces cleaned with Cleaner Degreaser should always then be treated with POR-15 Metal Prep before painting.
Caution Cleaner Degreaser may stain alloy surfaces.
