Worked for me
Seven years ago I decided to put some teflon impregnated white plastic strips cut used by some appliance installers to move heavy items and avoid marring floors. I cut one of these (had to bargan with the fellow who installed a new fridge at my home)into two long strips just wide to fit in the slot (track) that holds the hatch and about three inches shorter that those tracks. These are about 1/8 inch thick and quite slippery. I put a small glob of silicone sealant behind the aft end of each strip (about three inches forward of the aft end of the wood strips that secure the hatch) to keep it from sliding out when the hatch is opened. The result is no squeeks, smooth sliding, and easy cleaning. Cuts down the chance for wear. I should probably add that my hatch was starting to show some fairly heavy wear from the constant sliding friction before I did this. Since I remove the teak each winter, I clean each strip (and the tracks) completely in both the fall and spring. This has been sufficient.I rubbed a wax candle on the tracks to lubricate the hatch for a while before I ran into this slippery plastic. It did work, but I have been much happier with the "teflon slides."
