STP Carb Spray Cleaner 500 ml, Cleans and Protects Carburettors, Linkages and Automatic Chokes, Mechanical Car Cleaning Products, Made in the UK

I recently tried the STP Heavy Duty Car Brake Cleaner, and I have to say, it impressed me. The 500ml size is just right for tackling a few brake jobs. What I really liked about it was how easy it was to use. The spray nozzle provided a nice, even distribution, which made cleaning my brake components a breeze. I sprayed it on, let it sit for a moment, and wiped everything down—super satisfying to see all that grime just melt away! It’s great for getting rid of dust, dirt, and any leftover oil. After using it, my brakes definitely felt smoother, and I could tell the stopping power was improved. The scent is a bit strong—but hey, it’s a cleaner, so that was expected. Just make sure you're in a well-ventilated area when you use it. Overall, if you’re looking for a reliable brake cleaner, this one does the job well without breaking the bank. I would definitely recommend it to others who are DIY-ing their car maintenance!

Works very well and super price

After putting it to the test, it's clear that this product is a competent and reliable solution for routine engine cleaning, though it's important to approach its claims with realistic expectations. Packaging and First Impressions: The 500ml aerosol can is standard for such products, easy to handle and direct. The "Professional Series" branding suggests a more potent formula, hinting at its ability to penetrate and dissolve grime. Effectiveness and Performance: When it comes to its core function – removing oil residue and grime – the STP Engine Degreaser performs commendably. It effectively breaks down the common oily film, light grease, and surface dirt that accumulate on an engine over time. Spraying it on and allowing it to dwell for a few minutes before rinsing certainly makes a noticeable difference, leaving surfaces cleaner and looking tidier. However, it's crucial to manage expectations. While the product does clean, it's not a miracle spray. Those hoping for their engine to look factory-fresh or "brand new" after a single application – or even multiple – will likely be disappointed. Heavily baked-on carbon, deep stains, or significant discoloration that has accumulated over years will largely remain. For truly stubborn deposits, some manual agitation with a brush will still be necessary to achieve the best possible results. Claims vs. Reality (Heavy Dirt & Restoring Performance for a Smoother Engine): The claim of penetrating and dissolving "heavy dirt and deposits" holds true for oil and general road grime, but less so for deeply ingrained, caked-on gunk that has become part of the engine's surface texture. Regarding the promise to "Easily and Quickly Restore your Engine's Performance for a Smoother Engine," this is where the link is more indirect. A clean engine certainly allows for better heat dissipation, makes it easier to spot leaks or other issues, and facilitates maintenance. In this sense, a degreased engine contributes to optimal performance and can indirectly lead to a "smoother" running engine by enabling better diagnostic work and preventative maintenance. However, the degreaser itself doesn't directly enhance engine mechanics to make it run smoother in a performance sense, its role is purely cosmetic and facilitative. Safety and Application: A significant advantage of this degreaser is its safety around electrical components. This is a major concern when cleaning modern engine bays, and STP has clearly formulated this product with that in mind, providing peace of mind during application. Its aerosol format makes it relatively easy to apply to various nooks and crannies. Conclusion: The STP Engine Degreaser Professional Series 500ml is a solid and effective product for routine engine bay maintenance and the removal of common oil residue and surface grime. It's easy to use, and its safety around electricals is a genuine benefit. For those looking to keep their engine bay presentable and facilitate easier visual inspections, it's a worthwhile purchase. However, if your goal is a show-car level deep clean that resurrects an old, heavily soiled engine to its original glory, be prepared for additional elbow grease and perhaps a dedicated multi-step cleaning process. It's a highly capable cleaner for what it does, but remember: it cleans, it doesn't miraculously restore.

excellent quality, fast delivery, used several times and all works perfectly. Highly recomend this... many thanks..

Used on Honda mower that was hunting. I lo bought carb seals etc just incase. I removed filter housing and filter. Started mower on choke/ start. Started mower. Left to run for bit. Whilst running sprayed this into air intake in short bursts until it ran smooth (which was only a few shots. Switched choke to run and done again. Black sooty smoke from exhaust every time. Ran clean and no longer hunting 👍🏻

Excellent

I have used this product before and it is excellent.

Says what it does on the tin, very good for removing oil. Have used it on my lawn mower to clean carburettor. Will be buying it again, when it runs out as you don't need a lot.

all good
