P&S IRS Foaming Auto Shampoo, Gallon

IRS, the red soap on the P&S Pro Series shelf, is a highly concentrated liquid car wash soap for hand or machine use. P&S rates the concentration at 128 to 1 and describes it as super sudsing and cherry scented, producing a thick long lasting lather with good rinsing qualities that does not leave streaks behind. The maker positions it as strong enough to lift heavy dirt while staying mild enough for every day washing, which is the balance most home washers actually want.

Dilute at the rated 128 to 1 into your wash bucket or into a machine feed. Rinse the car first, wash from the top down, and rinse thoroughly before drying. At that ratio a single gallon makes an enormous amount of wash water, which is why this size shows up in shops and in the garages of people who wash every weekend rather than twice a year.

The gallon is dispatched by the supplier. Sold through Shopify Collective and shipped to you directly by Pal Automotive in Piscataway, New Jersey, usually within one business day, with its own tracking. Not made or shipped by Sniff and Shift. Not eligible for our free local delivery. Read who they are on our Meet Pal Automotive page, and see the rest of the range in Car Wash Soap.

Wash day and dog bath day tend to collide, so our freeze dried dog treats are useful currency once the hose comes out.
