            Rust:

          Treating rust stains is time-consu-
        
        
          ming, and requires patience. Hard-wearing,
        
        
          light-coloured fabrics and woollens can be
        
        
          treated with lemon juice, and then washed
        
        
          and rinsed thoroughly. Dark-coloured and
        
        
          delicate fabrics can first be treated with
        
        
          spirit of soap, then lemon juice, and finally
        
        
          dabbed with some pure spirits. A simpler
        
        
          way is to use a proprietary rust remover for
        
        
          fabrics. It is vital that rust stains are remo-
        
        
          ved as soon as possible, as leaving them
        
        
          for too long can cause permanent damage
        
        
          to the colours and fibres. Do not use chlori-
        
        
          ne bleach on rust marks!
        
        
          
            Resin:
          
        
        
          The best way of dealing with resin is
        
        
          to place the item in the freezer, then scrape
        
        
          the resin off and treat any lingering stain with
        
        
          alcohol, spirits, spirit of soap, turpentine or
        
        
          cream of tartar. Absorb residual moisture with
        
        
          blotting paper. Old dried on resin should be
        
        
          softened with butter to start with. The resin
        
        
          can then be scraped off carefully using the
        
        
          blade of a knife, and the remaining stain
        
        
          washed with spirit of soap.
