where do you buy those 14.1 oz. propane tanks…and can you use those 16 oz Coleman tanks.

What can I use? Tried vinyl cleaner, lysol etc.

So we decided to get a Weber grill but have questions about some of the differences between different models of Weber grills. I checked Weber’s website and they have no information about the following::
1. One type of grill has a “crossover” ignition, while the other type has an “electronic crossover” ignition. What’s a “crossover ignition” and what’s the difference between the two different types of ignitions?
2. One grill has porcelain enameled cooking grates, while the other has porcelain coated cast iron. When the grill has porcelain enameled cooking grates, what material does the porcelain enamel cover?
3. Is a sideburner worth the extra cost?
Thanks for the help.

Steaks at room temp before starting.
Season them well
Direct heat no cover
turn 180 deg after 3 min
in another 3 min flip over
after 3 min turn 180 deg
remove from heat in 3 min.
This gives them nice diamond grill pattern and MED steaks.
(Vary time to your taste. )

I can’t see spending $70 on grill grates for a grill. Is there a universal so to speak, replacement for a weber b series?
