Dr. Bronners 371592 Sal Suds Cleaner Liquid 16 oz.

Anyone who mixes this with vinegar and water in a quart size spray bottle for bathroom cleaning: how much vinegar do you use?

Does this work well cleaning ovens or a gas stove-top? I'm looking for an alternative to the usual Easy-Off.

is this unscented or scented on its own? I know you can buy it scented or add you own oils to scent. But is this Sal Sud the unscented one?

Is this safe to use on travertine floors?
