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.

Works great and fast.

This is an excellent product. I use it to clean farm equipment and it works better than anything I’ve used before. Highly recommended.

Works amazing

Excellent a little goes a long way! Definitely worth my money.
