Hi Bruce, Yes customize sizes are welcomed. No special cleaners are necessary with our zinc tops. We seal them with a very durable metal sealer. Simply clean up with a mild detergent like dish soap, water, and a non-abrasive sponge/cloth. We do not see to brick and mortar. Everything is made in our Providence, RI workshop shop and displayed online. We can send you a zinc sample if you like so you can see the finish. They are 10X10 1.5" thick samples and give you a good sense of what the table top is like. You can call Houzz to request a sample or request one thru our website.

Thank you. I would like a sample--can I request one with this email?

Since is a public comment, I wouldn't want your info exposed. You can request it thru this linkSample Request Form
