text: Oil does melt plastic.. augeo again does melt plastic .. I've not had any issues in the years of selling and neither of any of my customers.. I make sure mine are dry tho. Yes they don't last as long but I know there ok , I've used in all 4 my hoovers.
  
  I mix mine in 100g quantities as its easier and leave in tubs , take out when required , I couldn't tell u how much it makes 😂
