Right, who actually reads someone else's trash and thinks it's a sign from the universe?

Well actually it's more like 30 if you know the trick to it...

Used to think any sealer was better than none, but that yellowing was a rude awakening I wouldn't wish on anyone. The water-based penetrating kind from a tile shop really does soak in and bead up water without changing the color at all. Your mileage may vary, but for grout you can see every day, I'd save myself the headache of fixing it later.

Have you checked if your beans are old enough to be fully degassed yet?

My neighbor did the same thing with a $20 air mattress pump last summer and it melted on the second use. That cheap inflator story fits right in with how people buy the lowest priced option on everything from phone chargers to garden hoses, not realizing the first failure always costs more than the upgrade would have. It is a pattern across almost every product category that the savings upfront just turn into hassle and replacement costs later.
