Married and purchased a few things. What to try first.

I'm married seven years and things have cooled off slightly. I want to use some things to get my wife's Lobito up a little. I purchased ad certo, adriotics turn up the heat, instant shine, and ammunition.

What should I try first and are there any other products I can try,
Also can you recommend something for her to use. I'm not gonna tell her at first unless I see results.

Also is there anything about adriotics products that I should know? It seems that there is some hatred toward them in this forum. I don't need to know anoint all the dirty laundry just if the products are the real deal.

Thanks Nicola
