3D Grand Blast Engine Degreaser – Heavy Duty Biodegradable Cleaner for Engines, Wheels, Exhausts & More – Fast-Acting, Non-Staining – Made in USA – 1 Gallon

Does what it says extremely well

Was pleasantly surprised to find that this product works really well. I have two marine diesel engines to de-grease before painting with years of crud and grime accumulated around the front of the engine. Baked on belt dust with oil that had weeped from the valve cover and around crankshaft seal. I have tried other water soluble de-greasers but found most of them to be ineffective. The 3D Grand Slam worked like a charm. I have used the product without diluting and sprayed it on with a simple spray bottle. Let it stand for 10-15mins then agitated with a soft bristle brush. Let it stand for a further 10 mins, a second spray down and then a good rinse with the water hose. I'm really happy with the results. I'll probably spray the engines with a good parts/brake cleaner to ensure there's no possibility of any surface issues (not sure if it's necessary, just me being cautious) then hit them with a high heat paint. I'll also use this in the bilge around the engine position where diesel and oil have sat for a very long time and judging by the results so far with the engines I'm sure this will be a success too.

I am really not one to write reviews but I feel like this is a must. I use this 100% (undiluted although the instructions say otherwise but I find undiluted works best) with a pressure sprayer to apply it to the engine and let it soak for about 1 minute or 2 followed by a pressure washer rinse and I have to say, this product leaves the engine SPOTLESS. The oil and grime literally melts away. No need to use a brush for help, although it does not hurt. I have washed very dirty engines before and sometimes I have to do 2 applications but thats it. In addition, it does not leave any residue or after smell. I highly recommend this product.

to be honest, I trying so many products it doesn’t work to well when i using this 3D Grand Slam Engine Degreaser it does help and save me so much time

This stuff is amazing! You put it on a grease spot and can immediately see the oil rising to the top. Works great on engines and concrete and asphalt. I use it professionally now for all my degreaser needs. It’s versatile, removes oil easy, not overly smelly, easy to wash away. Easy to use in sprayer bottle

I have this cut to 33% strength and it works. Yes you still have to scrape off the chunks and brush thick spots like any other degreaser. This is not some fantasy Ai product that you just throw in the general direction of grease and its magically spotless and even repainted. This is a real life quality degreaser that works well. I have used it on farm equipment, engine bays, and even my truck exterior. Did not harm my paint at 33% strength.
