Hey guys, I moved to my new home n got those bolt less metal racks with wooden planks for the bomb shelter abt 9 mths ago. Few mths ago realized that the wooden plans got really mouldy, so I wiped the planks clean. But recently I checked n found that the planks got really mouldy again! So I tried using bleach-based mould cleaner to clean the planks, but I'm still really worried that the mould will come back. I'm not sure if it is due to the wooden planks or because the bomb shelter is nex to the rarely used guest toilet. Would appreciate if anyone can advise if i should juz switch to metal planks? If yes, do those companies only sell the metal planks, or I muz buy an entire new set of racks? Thx!
