Meguiars and all other on the shelf auto producs are substandard "avereage crap!" will not remove stains but rather discoulor leather! go to your local Horse sadle retailer and get:
effax® Leather-Cream-Soap
Effax Leather Balsam
Top notch, supiriour quality used by Ferari, AMG, Lambougini etc Car show detailers. It reguvinates soft and hard leather sadles from worn to new!! and is around $20 each for about 100 applications!
I even use it on our leather sofa! it's jaw dropping amazing!!!!!
