What can DS2 and Hydrox do?

[cookiemonster]

I have just received my first order of ds2 and hydrox. I have some questions.

1. Is the performance of these solutions affected by being exposed to the cold. I keep my solutions in my van overnight and it is getting very cold now?

2. What can I clean with these solutions and what not. Do they do upholstery with out colour bleed or risk of browning?

3. Can they be used as a spotter and can they be used with hwe cleaning as a prespray before being extracted?

4. If they can be used as a spotter will they remove urine and vomit or any sort of dye based stains?

Thanks
