Have had to deal with a few spots lately, some identified as 'chain oil' in a mechanical workshop showroom, and other 'unknown' varieties in a rest home.
Have done the recommended treatment: vacuumed both ways, sponges,brushed in, vacuumed both ways, sponges,brushed in,...spot still showing... pre-spray,more sponges, brushed in, vacuumed both ways....whew! but sometimes are still left with a slight mark.
Should I be using the spot cleaner (which I have not used yet) do you think I would get a better result perhaps using it earlier?
I should comment that with some spots and using the above procedure I have had real success ... but not all the time.
Would appreciate your advice.
