We have white formica counter tops in our kitcchen and over the years (9),and have been all sorts of store bought cleaners,lately we have been using clorox clean-up,now we have yellowing spots that will not go away even after using bleach to get the stains out.Also the surface doesn't seem smooth to the touch,like it's gritty or rough.Any suggestions on cleaning and restoring our formica back to normal?
Thank you
Jay
