Bests & Worsts Reviews from Amazon

Bought this to clean windows of 3K sqft ranch AFTER applying Wet & Forget Roof & Downspout Cleaner. (expecting those products to splatter on the house & windows during application) You'll see in other ratings how people moan that this product does not leave windows "spotless" or anywhere close to hand-washing. They're partially correct. Stress PARTIALLY. If you're talking about a typical urban / suburban home with years of that filmy-urban-suburban build-up on windows and screens ( that soupy mix of auto exhaust combined with several mos per year of intense humidity ) ... And if you're tasked with cleaning high-up, 1/2-2nd story windows, paladian and/or transom windows? YOU REALLY CAN'T GO WRONG WITH THIS PRODUCT! In all likelihood, you won't see "spotless results." But you'll take a lot of dirt off. You'll notice a cleaner window overall. And you'll save A LOT of money not paying someone $500-$2K to clean the same windows. WHAT I LEARNED / AFTER A FEW HIT-OR-MISS BLUNDERS (costing me 2 packets of solution) 1. Prep-Work is EVERYTHING. Mix the solution with hot water at least 40-60 mins in advance (it doesn't mix very fast even with hot water!). 2. Set the solution aside while setting up hoses and any other necessities. (ex. Ladders if you're spraying higher than normal) Be sure that your water pressure isn't diminished by attaching smaller hoses after larger hoses. And test-spray how far you can spray BEFORE you start. 3. TAKE NOTE as to whether the water pressure is lower-than-average (Ex. Saturday or Sunday in Late Summer, when everyone is watering grass & washing cars = probably not the best time to apply product BECAUSE you cannot spray as far) 4. NOTE THE TIME OF DAY. I've sprayed the product at dusk on a hot, super humid evening. < NOT THE BEST IDEA because the windows would fog up with the AC being in the high 60's. You you’re your windows to be BONE DRY after you apply it. Otherwise, you might be spending $$$ on a do-over, getting less for your initial money spent. 5. Keeping the overall context in mind – and realizing that you’re cleaning years of build-up off screens AND windows… Half expect to redo the windows if you’re not 100% satisfied with the results. Considering the price paid, no product is going to remove YEARS of build-up COMBINED WITH very little physical exertion. 6. BIGTIME Grain-of-Sale on the Infomercial claims of “clean up to X number of windows per packet!” I found that –after going through 1 entire packet screwing things up – 1 packet can maybe do 7-10 windows max. But hopefully my advice above will save everyone the hassle that I encountered.
