As an ex-professional carpet cleaner with experience using irons to get candle wax out of carpet, it'll work to get the bulk of it out, but you're going to still be left with some residue, wet looking wax stains, and color left behind. Especially on white fabric. And that was with using a professional candle wax removing solvent and then ironing it. I haven't tried the washing soda trick, so maybe iron out as much as you can and then throw it in the washing machine with washing soda while immediately after. Once you take it out of the washing machine, if there's still any waxy stain or color left behind, put it in a
bucket with
hot water and OxyClean for 24 - 48 hours. That's how I get my cotton dishtowels really white again. When they start looking dull, or get stained, I soak them in OxyClean and
hot water for 24 - 48 hours. If you have a
shower curtain that gets moldy on the bottom from not washing it often
enough, do the same thing, dip the bottom of the
shower curtain into a bucket of hot
water and OxyClean.
To avoid the wax issue again, put the candles on some kind of cloth placemat that you don't mind if it gets wax dripped on it. If anyone asks about the wax on the placemat, you can just smile and say,
"Yeah, but I can't bring myself to get rid of it. It reminds me of all the good times and good meals we've had by candlelight." Make it a memory instead of a mess. I'm kinda corny that way. But, I think we could
all use more corny in our lives.
