P21S 13001R Auto Wash Refill, 1000 ml, Clear, 33.8 Fl Oz (Pack of 1)

Used this product on my Ford F250 engine. Works great. I bought a pump sprayer/foamer as recommended on a youtube video. Literally takes 5 minutes or less to clean your engine. Remember to cover your alternator first. Great product. You can also use it to clean the under carriage of your vehicle too.

Excellent cleaner for dirty engine on my car as well as removing brake dust from the wheels.

Easy to use

Best product on the market

I was looking for a way to clean the engine compartment on my classic car without having to scrub every nook and cranny. After watching many videos online this product was in most of them. I used it the day after receiving it and I am very pleased with the results. While it is a little more expensive that other products I can say that it did the trick. I followed the instructions and with nothing other than a rinse with nothing other than the hose it delivered a clean engine compartment. The best part is it did not require a lot of the product and left everything looking like it came from the factory.

Works on engine as advertised. No scrubbing sprayed on and sprayed off with cold water. Fantastic product.

Having watched several videos I was convinced this was for my dirty 2003 Blazer motor. I may have not applied it correctly or didn't let it sit long enough in order for the product to do it's magic...not sure. The engine looked somewhat better but far from clean. I recommend this product for newer engines, not old dirty and grease bitten engines like mine. Didn't mean to give such a negative view, when half the problem was probably due to my part. Anyway, have fun and thanks

I have for years hoped for a product to clean my engine with ease and hoping for good results. All of my hoping has been answered finally and completely. All I did was cover my alternator and did a small amount of brushing some really greasy and heavily soiled areas. The prep took me about 10 minutes. I then sprayed the product on all surfaces? Let it set for another 10 minutes and then sprayed it all off with my garden hose. I used my leaf blower to help the drying process and used an old towel to better dry it off. All together about 40 minutes total and I’m OCD at that. The end result was as new looking as it possibly be and I hadn’t broken a sweat. I am thoroughly satisfied with this amazing product.
