mixing leather products?

[derek37]

I usually put my leather clnr/cond. in a small spray bottle. I used up the last in my bottle and was wondering if it would be alright to just add additional cleaner/condition of a different brand to the spray bottle instead of cleaning the bottle first.

Now i know it would be best to clean the bottle but if it wouldn't matter i'd rather not bother with.
what do you think?

Actually, I have no idea, but....
Anytime I change products in a container, I clean the container before putting in a different product.

I would wash it.
