Saved my outdoor egg chair cushions!

I have the egg chairs Walmart sold for the last couple Summers and the white cushions had gotten quite dirty from being outside over the last few years. I was looking all over for replacement cushions and couldn't find anything that would be as good and decided to try this product and the pictures speak for themselves. I used one big bottle to clean two chairs worth of cushions. I have tried washing these with soap and power washers and have never been able to get them clean. I just sprayed the concentrate on let it sit for a couple minutes and then spray it off, repeated as necessary. Amazing product.

Best Cleaner I've Ever Bought..

My nephew turned me on to this. I had mold on the end of my home that ugly green stuff not black mold. I bought some and WOW just attached to my water hose and started spraying. The mold and dirt came off with having to do anything but spray with water. I use it all the time on my home and porch. It's well worth the buy.

Be aware.

I bought this gallon refill to fill the spray bottle that connects to the hose but found the spray bottle tops DO NOT come off. I checked this on line and the answer to "are 30 Second cleaners spray bottles refillable?" NO. Duh!!! Fortunately I had a similar spray bottle with a removable top so was able to finish my project. The actual 30 second fluid is very good but was so disappointed (and very frustrated) to find this con.
