4315PS Cleaner (PURPLE POWER 32OZ)

This would be my 3rd bottle over the years as it is a very useful cleaner for really tough grease. This is a tad less powerful than full-strength oven cleaner therefore less abrasive. It is super powerful on old grease. I used it to clean up a 15 year old Weber grill and did not even have to wait much but a couple of m minutes before you see old brown/yellow/black grease disintegrate right before your eyes. I would recommend still wearing gloves though.

Works great for stubborn stains both on hard surfaces (like counter tops) and clothing stains.

Absolute best degreaser ever , helps keep my wheels and tires clean on my 2016 explorer

Very good product, just too good for everyday household cleaning

Great stuff. Used for years.

As I have gotten weaker and softer over the years, I have delegated responsibility for oil changes to the dealership. Unfortunately, my wife's car uses a recyclable crush washer for the oil drain plug, and multiple dealerships cannot seem to get it right. Thus, approximately 15-20 oil drips accumulated over the past 2 years, none bigger than a half-dollar size. More recently, I have been trying to catch potential drips with old pieces of cardboard. So today, with my kids and wife out at a birthday party, I pulled this product off the shelf and (mostly) followed the directions. I basically drenched about a 2 ft x 2 ft area with purple power, let it set for about 3 minutes, got inpatient, and took a stiff nylon brush to the area and scrubbed for about 5 minutes. I had the garage door open, and the instructions said not to let the product dry in, so I resprayed/reapplied a couple of times through the bubbles created by scrubbing. I then hosed the area off. I really couldn't tell how good of a job was done until I got my blower and blew off the water out of the garage. As the concrete dried, I could see about 85% of the area looking great. There were outlines of a few oil drips remaining, and I remember thinking that I was going to rate this product 4 out of 5 stars. Then, like a pitcher on a mound, I took my tennis shoe and starting "digging in" at the remaining 3 outlines of oil drops. And guess, what: It was like the oil outlines were just resting on top and my digging in motion got rid of them completely. Now, it is not pristine concrete, but I was not expecting it to be. I think I would describe the area now as having like dried rainwater from a car. It has a haze of dirtiness, but you can not tell that there had been 20 oil drip spots there. This product met all of my expectations, and thus 5 out of 5 stars.

Didn’t really remove stains from tire shine that they over did on my truck I’ll keep trying hope it starts to work better

Very effective product.
