Thanks mate, I did some serious research for how to bring leather back to life, literally spent 1 hour a day on them for close to 2 weeks lol but still a great deal for the purchase price plus ~$80 in cleaning products. The leather sucks in close to 600 mL of the oil in 2 weeks haha
Rug doctor:
first time your hire
roughly $40-50 for 24 hours hire
+ $10 anti foam solution
+ $15-$20 for the fabric cleaner
Will get 2-3 hires out of the chemicals, so once you do it the first time, means it averages out to a few bucks in chemicals. One of those must do's once you know about the gross-ness of seats when combined with sweat/dirt/oils that accumulate over a year. These are weekly vacuumed seats haha. I first learnt this when someone spewed in my magna, so I hired this to fix it, and the water was close to black and I said I will always clean seats annually after this moment hahaha
Also a life saver when you have people over and they stain your carpet, particularly when I had house parties a few years back when the parentals went on a holiday haha
