Farecla Professional Rapid Stain Remover
PRICE: £13.50/500ml (£27/lt) Contact: www.farecla.com
This oxalic/citric acid mix is sold as a stage two product, ‘revive’, in a four-stage process that includes wash, revive, restore, and protect as stages. It’s intended to be painted on with a soft bristle brush, left for 10 minutes and then rinsed off. A purple, thick and gloopy gel, it spread out easily. The colour in the gel meant that it was easy to see the areas that had been treated. Some light staining was still present once it had been washed off, and this required a second application to remove.
