How remove black tea stain

Bicarbonate of Soda

Got plenty of that. I'll give it a shot. Thnx, Jon. ;)

Bleach.

OK. I've tried bleach, oxi, bicarb, etc. All they do is bleach the stain white. Bicarb doesn't even do that. Problem is, the material leaves a glaze of stain which is still there, it's jes bleached white, so looks gone.

I've found not bleaching the stain and actually removing the thin patina of stain with mild abrasives to be a better solution. I use a dobie pad. I think my best defense is to not drink blk teas or even use my more valuble cups. ;)

Thanks fer the help. nb

I try to stay away from abrasives. By definition, they tend to scratch and if getting tea stains off a smooth surface is tough, then getting tea stains off an uneven, abraded surface is mission impossible.

Two abrasives I do use are -

Off the wall thought, make a paste of Biz (washing machine detergent) and water, then soak overnight . . . or longer. Apply elbow grease, then wash with very hot water and soap.

I use a paste of bicarb and dish washing liquid. the bicarb provides the mild abrasive without being to abrasive.
