I went into the local Dunelm shop. I purchased a single white brushed cotton sheet for £8. This was properly packaged. The cashier told me bedding linen could not be returned if it had been taken out of the packaging. The sheet did not look brand new when I took it out of the packaging. I washed the sheet. The washer smelled of a solvent. I washed the washing machine after washing the sheet. When drying the insidious solvent smell was taken up by the other fabrics nearby. I rewashed these. They gave off an insidious solvent smell. That is a lot of extra cleaning I can very well do without. I threw the Dunelm sheet away.
