i am removing a rug from linoleum that has been there for a time. The linoleum is yellow. How do you get rid?
Answers:
I know exactly the stains you mean. It is tough to do. Here is the process:
Restoration of “yellowed” linoleum
This should be only undertaken by a floorcare professional or contact cleaning company. It is a two-stage system where the second stage is only used if the first stage has not been as successful as required. The second stage uses a method of increasing severity and is removing part of the discoloured surface. Pre-test prior to using either method on an inconspicuous yellow area prior to beginning the larger stain.
Stage I. Bleaching
Using domestic 3% bleach, dilute in 3 parts cold water (if using commercial 12% sodium hypochlorite dilute 1 to 10 parts water). Apply by flooding the floor so that it stays wet for at least 15 minutes (place plastic sheets or thick cardboard over your track through the house). If the stains appear to be lightening, repeat process. Double rinse with cold water when finished.
Stage II. Bleaching and Scouring
This is a more aggressive method that is removing the top surface of the linoleum that has yellowed as well as bleaching any penetrated subsurface stains. Apply bleach or sodium hypochlorite as in stage I. Apply AJAX scouring powder (must be with chlorine bleach) whilst scrubbing with a black pad. Keep heavily sprinkling AJAX into new areas, then move the machine across the floor, then down the floor. Triple rinse the slurry residue after hand scouring the edges where the machine can’t reach. Then dry the surface which will be slightly rougher and without the yellowing. Apply sealer / finish as described under Application.
I hope this helps.

If this linoleum is indeed very old, more than likely, at some point it has probably been waxed which will turn yellow over time. First, I would suggest getting a good quality wax stripper from the hardware store and follow directions. Next, follow that up with a good scrubbing using bleach and hot water. If you don't see any change, then you may have to resign yourself that the linoleum exposed to everyday traffic has simply changed color with time.
