Today I was cleaning a white carpet that had a lot of small grease stains the size of droplets. The customer when questioned said it was juice spilled and walking across the areas. I treated the stains with a degreaser spotter. When I returned to the room for cleaning the individual stains had spread and had a bluish tint. I rinsed with an acid rinse, no luck. Then followed with just hot water extraction. Then followed up with browning, it was better but I could still see bluish tints in certain areas. Any suggestions?
