Hi everyone! I recently purchased two used loveseats. They are in excellent condition/were rarely used- except they were kept in a sun room and have a lot of fading. They are a beige/sand color and I much prefer the bleached areas. I don't know the exact material- I'm assuming a polyester blend of some kind. In the photo the sections that look stained or in shadow are the original color and the lighter color is where it was exposed to the sun. I am hoping to fade all of it. I have a good place on the deck where I can put them in full sun. I was wondering about using vinegar/lemon juice/hydrogen peroxide to accelerate the process? Any tips or tricks are welcome. Thank you!

Editing to add- the difference is not as dramtic as it appears in the photos. also it came with several coordinated throw pillows that i will not be keeping and can use for “experimenting” with options
