Description
Product Overview
Prosoco PRS-46015-01GALCS Engine Degreaser is a high‑performance, concentrated cleaning agent designed for automotive professionals and DIY enthusiasts. Packaged in a 1‑gallon container, the formula weighs 10 pounds and measures 5.75 × 5.75 × 12 inches, making it easy to store in a workshop. The product is water‑soluble, allowing dilution from 4 parts water to 200 parts for economical use. Its non‑chlorinated, non‑fluorinated composition eliminates the need for aggressive solvents such as ketone or benzene, providing a safer alternative while still delivering rapid grease and oil breakdown. The degreaser emulsifies a wide range of contaminants, including adhesives and paint residues, and can be applied with a brush or low‑pressure spray for versatile cleaning scenarios.
Usage

Designed for engine bays, transmission housings, valve covers, and other metal components, this degreaser excels in environments where heavy oil and carbon buildup are common. Dilute according to the desired strength—light cleaning tasks may use a 1:200 ratio, while stubborn grime benefits from a 1:4 mix. Apply with a brush for targeted spots or use a low‑pressure sprayer to cover larger surfaces. After a brief dwell time, the emulsified contaminants can be rinsed off with water, leaving a clean, residue‑free surface ready for inspection, painting, or re‑assembly. The low‑hazard formulation makes it suitable for indoor garage use without the need for extensive ventilation or protective gear beyond standard gloves and eye protection.

FAQ
How do I determine the correct dilution ratio?
For light cleaning, mix 1 part degreaser with 200 parts water (approximately 1 oz per gallon). For heavy buildup, use a stronger mix of 1 part degreaser to 4 parts water. Adjust based on the severity of the grime and test on a small area first.
Is this product safe for use on painted surfaces?
Yes, the water‑soluble formula is safe on most automotive paints when used as directed. Apply a diluted solution, allow a short dwell time, then rinse thoroughly with water to prevent any potential spotting.
Can I use this degreaser indoors?
Because the product is non‑flammable and low‑toxicity, it can be used in a well‑ventilated indoor garage. Standard personal protective equipment such as gloves and safety glasses is recommended.
What makes Prosoco Engine Degreaser different from other cleaners?
Its concentration reduces the volume needed per job, it contains no harsh solvents, and it is fully water‑soluble, making cleanup and disposal easier and more environmentally friendly.
How long should I let the degreaser dwell before rinsing?
Allow the product to work for 2‑5 minutes on light soils and up to 10 minutes on heavy deposits. Do not let it dry on the surface; rinse with water promptly after the dwell period.
