For base protection while ironing liquids/sprays, powders or ultra-thin solids, teflon sheets are an excellent option. They conduct heat well, slide, last a while, but do not absorb.
Lint-free fiber towels/Fiberlene is durable, good heat conductor, absorbs, protects the base and also has a light abrasive/polishing ability.
Blue shop towels are more durable than paper towels and are thicker. They are poor heat conductors and you need more heat to achieve the same heat necessary to melt wax and absorb excess wax.
If you are trying to remove excess wax, I find it's far easier, quicker, fewer steps, and less material usage to:
1) Minimize how much wax you do apply
2) Immediately after ironing the wax, perform a 'light hot scrape' using moderate pressure to squeegee/scrape off the excess.
You only need a thin layer of wax and light scraping off the excess still leaves plenty of wax to cool and perform a final scrape and brushing.
