Sorry, this is possibly the most boring thread known to man, but the fabric straps on my DS's high chair aren't removable, and they've become pretty smelly and dirty over time. I've tried scrubbing them with washing up liquid and a sponge, and tried CIF spray, but the smell remains. I'd rather not use harsh chemicals because of DS's proximity to the straps - does anyone have any tips on how I can get them clean and fresh? Am at the point of buying a new high chair, which seems crazy...
