Yes it would be ok. If I can hire someone off the street and give them very little training and they don't damage the furniture, any member regardless of knowledge or experience can use a power washer and not damage their furniture if they follow what I have written. Many of the workers I had, I had no real way of training them. They were illegal aliens and I couldn't speak Spanish. The bottom line is I would not strip furniture without a power washer. It cleans the residue of the remover off the furniture so much better than anything else. Any residue of remover can have adverse reactions with the new finish. Except for a little stain left most furniture comes as clean as a newly built piece of furniture that has had the grain raised with water. It doesn't roughen the wood, it just cleans it.
It's so easy that an illegal alien can do it.
You are entitled to your opinion, and there's no need to have a story to make your methods sound right. It's not a matter of who is right or wrong, and having to cover all the aspects of a method or procedure with what is in your opinion facts that prove you're correct, is really unnecessary.
You could just state your mind, and if someone doesn't agree with you...so what!! We don't all think or work alike, and have diverse backgrounds. Some methods may have evolved through trial and error, others may have been something "heard on the grapevine". At least with a choice, members have a few alternatives to try out. It keeps them busy, and serves as a learning experience.
Opinions are just that, and we all have our own. They don't constitute fact. You are entitled to yours. Your opinions about lacquer being too soft, or Minwax not retaining color, or methods for applying grain filler, or dislike for waterbase polyurethane...don't need to be explained to be construed as correct. There's always the option for responses to disagree, as what was stated may not have worked out the same for someone else. Those problems are worthwhile to discuss, as it may save someone time or money in the end.
