My kitchen bench top has these marks (see the picture) after putting a teapot on it for a few seconds.
Any solutions!
Thank you in advance 🙂

Oxalic acid, either in crystal form or as part of a pressure treated deck cleaner/brightner will chemically dissolve the stain. If you use the crystals, use all normal precautions for acids (eye, hand, clothing). You can sparingly apply with a small nylon artists brush. Try 5 min increments (5 on, wipe off, 10 on, wipe off) until the stain starts to disappear.
Once stain disappears, neutralize wood with borax diluted in water or bicarbonate of soda in water.
Replace color with dyes or pigment stains. I like Transtint for its ability to be blended and mixed with either water or alcohol. If you don't like the color direction, you can use bleach and start over.
Once happy with the color, seal it in with a dewaxed shellac. Then top coat with your favorite polyurethane. You may be able to blend the areas by shooting spray poly through a circular mask (5" hole in a 12x12 piece of cardboard, held 5-10 inches away from the floor) which will give you a graduated spray. Practice first.
Usually tops like that are built by fitting a base sheet (usually particle board for flatness and smoothness) and edging it with hardwood using miter joints. Then laminate is applied across the entire surface with contact cement. The laminate is then trimmed flush with a router, and a bevel or more detailed edge is routed into the hardwood and laminate simultaneously.
Stain (optional) and several coats of high-quality sealer finish the job. With this technique, virtually any shape is achievable with basic carpentry skills.

As already stated... sanding is the answer. Start with a course grit (small number, like 60) sand until the marks are gone. It's much easier if you can borrow or rent a "random orbit sander", many can be hooked up to a vacuum to control dust.
Sand the entire area... ideally the entire countertop, so you don't create low spots. Then work your way up (higher number grit) maybe 110, then 240 then 300 or so. At that point you ought to be able to seal it with some kind of penetrating oil... mineral oil even works fine. Look for "food safe" finishes at your local store.
