Spike it makes a bottle of neutralizer and it works good. If you ever get spike it on your fiberglass like I did. White fiberglass interior and purple spike it is a bad combo. I found that when using the spike it to also use a magic eraser bar on the gel coat and it works awesome. just pour the neutralizer on your carpet and it will take the stain out. as for just general cleaning of my boat carpet I use a 50/50 mix of water and vinegar and use a water house to wash it out. I have always been told that a pressure washer hurts your carpet and can damage the glue adhesion. I hope this helps.
