spilled oxycleaner

    spilled oxyclean on my travertine. now when those areas get wet looks like a water stain. when dry looks fine. when i sprayed sealer on, still looked like a water stain, but when the sealer dried it looked fine..so, do i just need a better sealer? it 's two pretty large areas...do i just get the slab rehoned and start over? (im using a spray sealer, apply 60seconds and wipe off kind) thanks!
