I searched the forum for getting yellow off of steps. Tried the vitamin C tablet and it did turn white. I tried it on the skimmer too and in some places it turned white but in other spots it stayed beyond yellow and it just looks rusty. There is also a line just under the skimmer that looks like rust on the vinyl.
Anyone know what's up with that rust?
As for the yellow stains, do I have to treat all of the water or just kinda spot clean in places? Will whatever I treat with take care of the rust too?
