P21S 13001B Auto Wash W/Sprayer, 1000 ml, White

I cleaned my car engine bay for the first time after driving this car for 3.5 years lolFirst of all and most important to cover the alternator, I used Walmart plastic bag to cover it. I kept spraying P21S for 2-3 minutes overall, and then let it for 1 minute(DONNOT LET IT MORE THAN OR LESS 1 MINUTE) I didn’t scrap anything, now the key here is you've got to rinse thoroughly don't be cheap with the water here you've got to get all that total auto wash off, remove the plastic bag fro the alternator if you covered it. I used the garden hose rinsing the product off, I used a leaf blower just to get the loose water you don’t have to worry about getting every bit off, finishing up with a rag wiping down the plastics especially the ones that have flat surfaces to get any remaining water. All that took no longer than 5 minutes. Finally, I took a drive for 10 minutes.

A little pricey but worth it in my opinion. Have used this to clean the engines on all of our vehicles and it does a good job. Pretty much just spray it on and a few minutes later rinse it off.

Expensive, but worth it. No other product comes close for cleaning up a neglected engine bay. You barely need to agitate it with a brush and it leaves no spots if you rinse very thoroughly. I love this stuff.

This product works pretty well. Used it to clean the engine bay of my 06' F-150. I let the engine get to ambient temperature and covered the alternator with a plastic bag. I then soaked the engine bay with the product and let it sit for one minute. I then hosed the entire area down with relatively low-pressure water. After rinsing down I removed the plastic bag from the alternator and immediately started the engine. After letting the engine warm up a bit, I drove the truck for about 20 minutes. After parking the truck, I inspected the job, and the engine was quite a bit cleaner. Note that on extremely heavy grease and oil built up areas will take a second dose in that area. All in all, I am pleased with the results.

Very skeptical. I was definitely happy I tried it. I didn’t believe the hype. Used as an engine cleaner on a 2016 Ford Explorer Police vehicle. The engine was….bad. You know how hard these vehicles run for years. Sprayed the cool engine with this, let sit for about 3 minutes. Took a garden hose and sprayed it all off. Absolutely worth every penny. The engine bay actually looks like it’s right out of the factory. And NO scrubbing or dressing. Spray it on. Hose it off. Takes you less than 10 mins. Wish I knew about this years ago….

I bought this to clean my engine in my 2020 Mustang GT. I misted it down with water from a hose, applied this from the included spray bottle, waited a few minutes, used a soft scrub brush on everything, then gently rinsed it down. Came out looking showroom new.

This is a life saver for not only cleaning but smell too. I hd an issue where the scent of rodent urine was inside my engine. I did everything to clean that engine but the smell was still there. Walking past my car, I can still smell it with the hood down. I was embarrassed whenever I took my car out because of it. I decided to try this out and this surprised me after everything I’ve tried. Not only was it easy and safe to use, but it clean EVERYTHING. My engine looks brand new and all the nasty smell was GONE. I don’t mind buying it again, this was WORTH the money. My engine no longer smells and it still runs fine too.

Great product Tried out on 2009 Ford Ranger followed instructions engine looks like new great product
