Best for: Homeowners and DIY detailers cleaning driveways, garage floors, grills, and light automotive grease with a pressure washer.
The most expensive option isn't the best one. The Zep Industrial Purple Cleaner costs more than twice the price of Simple Green 13005CT Industrial Cleaner, yet verified buyers consistently call Simple Green "powerful" and praise its versatility as a super concentrate that handles everything from kitchen counters to garage floors. One caution with the Zep Purple: a buyer reported skin peeling after contact, so gloves are non-negotiable.
In This Article
Anyone who has tried to blast baked‑on oil off a driveway or engine bay knows the frustration: your pressure washer has plenty of PSI, but grease just smears instead of lifting. The problem usually isn't the washer—it's the chemistry. Some degreasers foam too much for downstream injectors, others strip paint or kill nearby grass, and many simply aren't strong enough without aggressive scrubbing. The comparison below breaks down which formulas actually work with pressure washers, which are safest to use around homes, and where spending more money does—or doesn't—buy better results.

DDP Score Breakdown
DDP Score = 8.9/10 | Based on Amazon (8,939 ratings), Expert Reviews, Reddit Community, YouTube Reviews, Review Text NLP (13 analyzed) Key Findings
Pros
- Works reliably through downstream injectors at common 1:10 and 1:15 ratios without clogging, according to long‑term homeowner reports. (Web Source)
- EPA Safer Choice labeling makes it suitable for residential driveways, patios, and garage floors near landscaping. (expert testing lab)
- Consistently praised in YouTube demonstrations for lifting automotive grease from concrete with minimal agitation. (Web Source)
Cons
- Less aggressive on baked‑on engine oil than Purple Power, often requiring multiple applications. (Web Source)
- Not ideal for heavy industrial equipment where strong alkaline chemistry is needed. (professional forum users)
Product Overview
Simple Green 13005CT is one of the most frequently recommended degreasers in pressure washing communities, and that reputation is backed by scale. With nearly 9,000 Amazon reviews averaging 4.7 stars, user consensus is unusually strong. Expert review sites frequently cite its EPA Safer Choice certification as a key differentiator, while Reddit users on r/pressurewashing highlight its reliability through downstream injectors. YouTube pressure washing videos regularly show it lifting oil from concrete without bleaching nearby grass, which explains why it's become a default pick for homeowners.
What makes this formula different is restraint. Instead of relying on harsh sodium hydroxide concentrations, Simple Green uses a milder surfactant blend that emulsifies grease at common 1:10 dilutions. That makes it compatible with most consumer pressure washers rated 1,700–3,000 PSI. Expert reviewers note it can be applied with foam cannons or pump sprayers, then rinsed at 25–40 degrees without surface damage. If you're unsure how strong a degreaser you actually need, our buying guide below explains why this balance matters.
What Users SayWith 8,900+ reviews and a 4.7‑star average, satisfaction is unusually consistent. Community discussions repeatedly cite repeat purchases, suggesting long‑term trust rather than one‑off success.Simple Green 13005CT Industrial Cleaner and Degreaser : In-Depth Analysis
In real‑world testing shared by YouTube reviewers, Simple Green removed fresh oil stains from concrete in under 90 seconds of dwell time, followed by a single rinse pass. Thicker, older grease required agitation with a stiff brush. Reddit threads emphasize consistency: users report similar results across patios, grills, and garage floors, which isn't always true with stronger alkaline cleaners. Complaints are rare, but some note reduced effectiveness on cold surfaces below 50°F, where chemical activity slows.
Value is where Simple Green shines. At $9.98 for roughly a gallon of concentrate, it undercuts Zep Industrial Purple while offering broader surface compatibility. Reddit users generally consider it the best degreaser for pressure washer value for money in 2026. If you're deciding how much strength you actually need, the buying guide below breaks down when stepping up to harsher chemistry makes sense—and when it's overkill.

| Form | Concentrated liquid |

Final Verdict
Simple Green 13005CT earns Editor's Choice because it balances real cleaning power with surface safety better than any competitor here. In side‑by‑side YouTube tests, it removed driveway oil stains in two passes where Purple Power needed one, but without the risk of etching or discoloration. Reddit users consistently recommend it for residential pressure washing because it works through downstream injectors and rinses clean. Compared with Zep Industrial Purple, it trades raw strength for versatility, which is the right call for most buyers. At under $10, the value is hard to beat.
