Hi we installed the american oak timber benchtop from the kaboodle range and was advised by one of your team members to oil it with the 'bondall monocel timber benchtop oil' which we applied 3 coats with sanding and 24hr drying inbetween. It has given a smooth finish and good colour but after barely a week of installation has seen lots of black water stains that are now irreversible. Very annoying and hard to control around the sink area. is there something to resolve this please?
