Can mixing detergents be harmful?

I always do that (add one brand on top of another if I like this or that bottle better) and I’ve never had a problem.

I like to live on the edge.

I think detergents are ok to combine, but bleach with other cleaners can be toxic.

I don’t think there is anything dangerous about it. I sometimes mix laundry soap in the machine. I don’t usually do it in the bottle though.

@chyna Makes a good point about bleach though. Cleaners like bleach and soap scum and calcium removers should never be combined. Be careful with those spray type cleaning liquids.

By the way, in my original question – I meant Costco BRAND not Bland…..

If bleach is an ingreedient than be very carefull. It reacts with a lot like ammonia, rubbing alcohol, vinegar etc.. those combinations can be lethal releasing chlorine gas, chloroform and others. I’m sure dish soap and most laundary detergent is ok though. Just watch out for bleach.

Without knowing the exact ingredients and being a chemist, I doubt anyone could know, but I’m guessing it would be fine. Manufacturers know that people combine hand dish detergents together all the time,

In general, always research before you combine two chemicals that are unlikely to be used together (such as bleach and ammonia (produces a very toxic gas) or vinegar and hydrogen peroxide (produces a corrosive acid).

No they aren’t dangerous. All soap is made out of the same basic ingredients—alkaline substances and fats. (Fire ashes and animal drippings!)

Some dish soaps do contain chlorine, so caution is advisable.

NEVER mix bleach with ammonia because they don’t react well together!!!!!!

I often mix Dawn with the remnants of a generic dish detergent to save space & increase the efficiency of the cheap brand & I’ve NEVER had a problem!!! I have also mixed a named brand laundry detergent with an generic brand with success. Sill, I’m ALWAYS leery & pay attention while combining…just in case there’s a first time reaction!!!

I don’t see why it would be a problem. Wouldn’t they have it as “Caution” if it were. There is no mention of bleach, amonia etc. in the OP.
