I have been using The Lab Co's Laundry Sheets in recent times as a replacement for the strong smelling washing pods I began to find intolerable with a respiratory condition. As these changed my life - no exaggeration - I was keen to try their unscented Spot Stain Remover.I find I've only occasional need for a stain remover - so the relatively small size of this 150ml/5 fl oz spray bottle for me is about right. Spot Stain Remover is, understandably, far more effective on recent as opposed to dried in stains.What I again like about this product is that it's unscented. Gel pre-wash type stain removers can literally take my breath away. This one doesn't. Easy to use, you just spray it on the stain - no rubbing in - and leave for 5 minutes prior to washing. Plus this is biodegradable, vegan and cruelty free. There's no Use By date on this - one to keep in the cupboard then you have it when you need it.
