I've just cleaned a rug that I picked up from a customer earlier in the week. When I collected it from him, it was already rolled up in his garage as he was having some flood restoration work done (the rugs were unaffected by the water damage).
I unrolled it to clean it, and there was a few marks on it, and it needed grooming & a clean.
I presprayed with pre-spray gold mixed with a tiny bit of oxibrite which was left in the sprayer from earlier in the afternoon.
When I stood back, a third of the rug down the side was considerably brighter than the rest. I was hoping it was the way the pile was lying and that it would go back to normal after grooming, but no such luck!
I cleaned it thoroughly, tried brushing it, but it's still noticably lighter down the one side.
I can't say hand on heart whether it was like this before spraying or not.
I've attached a pic, please take a look and let me know what you think - it's due to go back to the customer in a couple of days and he has 3 more for me to do.
It's a wool rug. Would you assume that this might possibly be sun bleaching?
