So, I've been using a wallpaper tray for about a year now to soak my wine thief, racking canes, autosiphon, airlocks, etc in to sanitize them. I would leave everything soaking in the tray so if I needed a wine thief to grab a gravity sample, everything would be sanitized and ready to go. It was uncovered, so after a while the starsan would be full of dead gnats and I'd have to replace the starsan regularly.
This worked fine until I abused the wallpaper tray once too often and it sprung a leak, so I headed to Home Depot to find another one to replace it and it turns out Home Depot does not carry wallpaper trays (I knew wallpaper was a dead form of decorating your home, but I thought the trays would still be available for some reason).
I could have gone to Sherwin Williams to get a tray, but I decided to walk around and look for an alternative. While wandering thru the garden area I stumbled across some plastic window box planters that were 24" long and did not have a hole drilled in the bottom. They did have a couple holes that were meant to be knocked out to let water drain out, but they were still sealed. They also come with a drip tray that I discovered fits nicely in the top of the planter and could act as a lid.
I ended up buying two planters so that they would be more stable nested inside each other. Also, the second planter acts as a safety backup in case the inner planter leaks. You'd probably be ok with one, but the planters are much more stable when you nest two of them and I want this to last a long time.
When I got them home, I decided to strengthen bottom areas that were meant to be knocked out by applying some JB weld to them (yes, I have to put JB weld on everything). This should prevent them from leaking in the future.
Below are pics of the finished product - the total cost for the 2 planters and drip tray lid was about $17, but I hope this will last much longer than a wallpaper tray. The only con about using the planters is that they are a couple inches too short to store my autosiphon in. I have to dip the autosiphon in one end at a time to sanitize it.
