Child ran off with a mug of cold tomatoe soup... bleurghh and poured it on fawn colloured carpet, borrowed my friends VAX last night and its got most of the stain out (yipee) BUT the water coming out of the dirty tank was revolting, I went over the whole carpet about 6 times til the water was nearly clear, but this morning it really smells musty and like febreeze smell. Will this fade? Should I bicarb the whole lot?
